The W4100 features a lightweight, rugged ABS handle that helps prevent user fatigue. It attaches rapidly to smooth, flat non-porous surfaces ranging from glass to metal. While in use, the CRL Wood's Powr-Grip® red-line indicator warns the user of any loss of vacuum. If the red line should appear during use, a special check valve allows re-pumping without loss of remaining vacuum so the user can continue working without having to reattach to the load. When the user is ready to release from the material being handled, a convenient valve lever enables the quick and complete release of the load.
Unlike other CRL Wood's Powr-Grip® hand-held vacuum cups, the W4100 comes with a distinctive blue pumping mechanism. This feature allows the user to discriminate between regular hand cups and the high-elevation vacuum cup at-a-glance, to assure that the right tool is being used for the job.
The W4100 is supplied with a protective carrying case. 8" (203 mm) diameter.
