Sink cutout accuracy is one of the most unforgiving aspects of stone countertop fabrication. A sink opening that is off by even a few millimeters produces visible gaps at the mounting clips, misaligned faucet holes, or worse—a completed countertop that requires costly rework before installation can proceed. The Aardwolf CTTS Sinkloc system was engineered specifically to eliminate this category of error by providing a physical, reusable template for the exact sink model being cut, verified against the actual sink before the stone is touched.

What Is the Aardwolf CTTS Sinkloc System?
The Aardwolf CTTS Sinkloc is a precision sink templating system that allows fabricators to create accurate, reusable templates for undermount, flush-mount, and drop-in sinks directly from the physical sink itself rather than relying on printed dimension sheets from the manufacturer. The system uses adjustable template components that conform to the specific sink being templated, capturing the exact opening geometry in a rigid template that can be used immediately for CNC programming or bridge saw cutting and stored for future use when the same sink model is ordered again.
Traditional sink templating using cardboard, plywood, or foam sheet requires cutting and fitting a template piece by piece against the sink, which introduces accumulated measurement and cutting errors that can add up to several millimeters of deviation from the true sink opening geometry. The Aardwolf CTTS Sinkloc eliminates this error-accumulation process by providing a systematic, adjustable template framework that positions against fixed reference points on the sink itself, ensuring that the resulting template represents the actual sink geometry rather than a hand-crafted approximation of it.
The system is designed for the realities of a production fabrication environment. The template components are durable, dimensionally stable, and easy to set up and break down efficiently. Once a template is created for a specific sink model, it can be stored and retrieved for any future job using the same sink, eliminating the time spent re-templating a sink that has been used dozens of times in the shop. For high-volume shops processing multiple kitchen and bathroom projects per week with a recurring catalog of sink models, the time savings from template reuse across a full year of production add up to a measurable improvement in shop throughput and profitability.
Compatible Sink Types and Applications
The Aardwolf CTTS Sinkloc system is compatible with the full range of sink types encountered in residential and commercial stone fabrication. Undermount rectangular and square sinks—the most common format in contemporary kitchen and bathroom design—are the primary application for which the system is optimized. The template captures the exact internal dimension of the undermount opening as defined by the sink lip geometry, ensuring that the stone opening matches the sink mounting surface precisely across the full perimeter.
Undermount D-shaped and oval sinks used in bathroom vanity applications are also handled by the Sinkloc system. These irregular curve profiles are among the most difficult to template accurately using traditional hand-cut methods, because small errors in the curve geometry accumulate into visible gaps between the stone and the sink rim that are immediately apparent once the sink is set. The Sinkloc system traces the actual curve of the sink mounting surface, producing a template that captures the true geometry regardless of how irregular or non-standard the curve profile may be.
For flush-mount and zero-reveal installations where the stone surface and the sink rim must be at exactly the same height across the full mounting perimeter, the accuracy of the opening template is even more critical than for standard undermount work because any deviation in the opening geometry produces a visible high or low point at the stone-to-sink transition. The Sinkloc system supports these precision applications by providing the dimensional accuracy needed to achieve the zero-reveal result that clients and designers specify with increasing frequency in high-end residential and hospitality projects.
Apron-front and farmhouse sink installations present their own templating challenges because the sink opening must coordinate with the cabinet rough opening geometry, the sink apron face position, and the countertop overhang dimension simultaneously. While primarily a countertop opening system rather than a cabinet rough-opening layout tool, the Sinkloc system provides the accurate countertop opening template component of this multi-dimension coordination challenge and is compatible with the full range of apron and farmhouse sink formats encountered in contemporary residential fabrication work.

Setting Up the Sinkloc System
Setting up the Aardwolf CTTS Sinkloc for a new sink model begins by placing the physical sink in a stable position on the work surface with the mounting rim facing up. The Sinkloc template components are positioned against the sink mounting surface at the reference points specified in the system instructions, and the adjustable arms are set to conform to the sink opening geometry at the inside edge of the mounting lip. The components are then locked in position, and the template is verified by checking that each reference point maintains consistent contact with the sink surface at the correct registration depth.
Once the template components are confirmed in position, the template outline is transferred to the template substrate—typically a rigid sheet material that can be directly mounted to the CNC router bed or used as a router guide for bridge saw cutting. The transfer process is designed to be fast and accurate, completing the full template creation in a fraction of the time required to hand-cut and fit a traditional cardboard or plywood template. For shops using digital templating systems, the Sinkloc geometry can also serve as the physical verification reference for a digitally-created sink opening file, confirming that the digital dimensions match the actual physical sink before cutting begins.
Verification of the completed template against the physical sink is a built-in step in the Sinkloc workflow that eliminates the class of errors that occur when a fabricator cuts from a template without a final check against the actual sink. Place the completed template back over the sink mounting rim and confirm that the template opening aligns with the sink lip geometry across the full perimeter before proceeding to the stone. This confirmation step takes less than two minutes and is the final insurance against the template error that, once cut in stone, is expensive to fix.
Integration with CNC and Bridge Saw Workflows
The Aardwolf CTTS Sinkloc system is compatible with both CNC router workflows and manual bridge saw workflows, making it useful across the full spectrum of shop equipment configurations. For CNC shops, the Sinkloc template serves as the physical verification reference that the CNC file dimensions have been correctly entered before production cutting begins. Running a paper or tape outline of the CNC file over the actual template and checking the alignment provides a fast sanity check that catches data entry errors before they produce a miscut opening in an expensive slab.
For manual bridge saw shops where sink openings are cut by hand, the Sinkloc template is used directly as a cutting guide, providing the accurate outline for the plunge cuts and curved routing operations that produce the finished sink opening. The accuracy of the Sinkloc-derived template is consistently better than a hand-drawn template traced from a manufacturer dimension sheet, because it is derived from the physical sink rather than from printed dimensions that may not reflect the manufacturing tolerance variation of a specific production batch.
Why Shops Invest in the Aardwolf CTTS Sinkloc
The business case for the Aardwolf CTTS Sinkloc comes down to error prevention and time savings across a production shop running multiple projects per week. A single rework event on a kitchen countertop with a miscut sink opening—whether that means remaking the top, grinding and patching the opening, or negotiating with the client over a visible imperfection—costs significantly more than the purchase price of the Sinkloc system. Shops that price this cost-avoidance correctly recognize the Sinkloc as a low-risk, high-return investment in production quality rather than a discretionary tool purchase.
The template reuse value accumulates rapidly in any shop with a recurring catalog of sink models. Once a Sinkloc template exists for a popular kitchen or bathroom sink, every subsequent job using that sink benefits from the template without any additional setup time. Over a year of production, this accumulated time saving across dozens or hundreds of jobs represents a meaningful improvement in shop capacity and profitability. The quality consistency benefit—every sink opening cut from a verified Sinkloc template matches the sink precisely—also reduces the quality variation that creates unpredictable installation-day fitting adjustments that slow crews and frustrate clients.

Aardwolf products are engineered specifically for the fabrication environment and carry the quality standards that professional shops demand for tools they rely on every day.
Training New Employees with a Standardized System
One of the less-discussed benefits of the Aardwolf CTTS Sinkloc system is its role in standardizing the sink templating process across a shop with multiple crew members at different experience levels. Without a standardized system, sink templating quality varies significantly depending on who performs the task—an experienced fabricator who has internalized the best practices will produce a consistently better result than a newer crew member working from informal guidance about how to trace and cut a cardboard template. The Sinkloc system codifies the best practice into the tool itself, providing a defined setup procedure that produces consistent results regardless of the operator experience level.
Training a new employee to use the Sinkloc system takes significantly less time than training them to produce reliable hand-cut templates, because the system guides the operator through the correct setup procedure rather than relying on accumulated judgment about how to position and trace a template accurately. The result is that new crew members become productive on sink templating tasks more quickly, and the quality gap between new and experienced operators on this specific task is substantially reduced. For shops with crew turnover or with seasonal volume fluctuations that require temporary staff additions, this training efficiency benefit translates directly into maintained production quality during staffing transitions.
Documentation of the template creation process is also simpler when using a systematic tool like the Sinkloc. The setup parameters for any template—the sink model, the registration depth settings, the date of creation, and the operator name—can be recorded in a simple log that provides traceability if a template needs to be verified or recreated in the future. This documentation habit is consistent with the quality management expectations of commercial and institutional clients who require traceability records for fabrication processes on their projects.
Comparing the Sinkloc to Alternative Templating Methods
The alternative methods for creating sink opening templates—hand-cut cardboard, plywood router templates, foam sheet tracing, and direct digital measurement—each have tradeoffs compared to the Sinkloc system. Hand-cut cardboard templates are inexpensive to produce but fragile, prone to accumulated cutting errors, and single-use. Plywood router templates are durable but time-intensive to produce accurately from scratch. Foam sheet tracing is fast but imprecise, particularly for curved sink profiles. Direct digital measurement using a probe or caliper requires accurate data entry into the CNC software and does not provide a physical verification reference against the actual sink before cutting.
The Sinkloc system combines the physical verification accuracy of a tool-derived template with the efficiency of a repeatable setup process and the durability of a reusable product that outlasts cardboard and foam alternatives by years of regular shop use. For shops that have experienced even one expensive rework event from a miscut sink opening, the comparison to alternatives makes a clear case for investing in a system that systematically prevents this category of error.
