Product Information
Full details
The Wood's Powr-Grip W4950 is a hand-actuated vacuum cup suction lifter designed for professionals who need to quickly and securely attach to smooth, non-porous flat surfaces. Its key benefit is providing a strong, temporary hold for lifting and moving materials like glass or tile, with a red-band indicator for easy suction monitoring. A potential caveat is its reliance on perfectly smooth, non-porous surfaces for optimal performance.

FAQs
What is the maximum weight capacity of the W4950?
The product description does not specify a maximum weight capacity. Always test suction thoroughly and use caution when lifting heavy objects. Refer to Wood's Powr-Grip for specific load ratings if available.
Can this suction cup be used on textured surfaces?
No, the W4950 is designed exclusively for smooth, non-porous flat surfaces. Textured surfaces will prevent a proper seal.
How do I know when to re-pump the vacuum?
The red-band indicator on the plunger will become visible when the vacuum level drops below the optimal point, indicating it's time to re-pump.
Is it safe to leave the suction cup attached for extended periods?
While the check valve helps maintain vacuum, it is recommended to monitor the red-band indicator regularly, especially for long-duration holds or critical lifts. Do not rely solely on the indicator without occasional visual checks.
What should I do if the plunger feels stiff?
Ensure the plunger mechanism is clean and free of debris. Light lubrication might be needed, but consult the manufacturer's guidelines. Avoid forcing a stiff plunger.
Does this lifter come with a warranty?
The product is eligible for the Powr-Grip Exchange Program, which suggests a warranty or replacement service. For specific warranty details, please contact Wood's Powr-Grip directly.
How do I clean the suction cup?
Wipe the rubber rim and surface with a clean, damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the rubber or create a slippery surface.
Troubleshooting
Suction cup will not hold vacuum
Ensure the surface is clean, smooth, and non-porous. Check the cup rim for any damage or debris. Ensure the plunger operates smoothly and the check valve is functioning correctly.
Red-band indicator does not show or retracts immediately
The plunger may not have been operated enough to create sufficient vacuum, or there is a leak. Re-operate the plunger and check for leaks around the cup edge. Ensure the surface is appropriate.
Release lever is difficult to operate
Ensure all vacuum has been released by operating the plunger fully in reverse if applicable or by holding the release lever down. Clean any debris from the lever mechanism.
Carrying case is damaged
Contact customer support for replacement options. The case is essential for protecting the lifter.
