The Wood's Powr-Grip N4950 is a hand-pumped vacuum cup built for lifting glass, polished stone slabs, and other smooth, non-porous flat surfaces. A durable metal handle drives the pump, a check valve holds vacuum between pumps, and a red-line indicator gives a visible warning if vacuum pressure drops. The cup ships with a protective carrying case and is eligible for the manufacturer's Hand Cup Exchange Program.

- Confirm the surface is smooth, non-porous, and free of dust, oil, or loose debris.
- Place the cup flat against the surface and pump the metal handle to draw vacuum.
- Watch the red-line indicator — if it becomes visible, re-pump the handle before lifting or continuing to carry the load.
- The check valve holds vacuum between pumps, so repumping does not release existing grip.
- Lift and move the load within the 125 lb (57 kg) rated capacity for a single cup.
- Release the valve lever to break vacuum once the load is set down.
- Store the cup in its carrying case when not in use.

It becomes visible when vacuum pressure drops, warning the operator to re-pump the handle before the grip weakens.
