8 in Woods Powr-Grip Vacuum Cup With Metal Handle
C.R. LAURENCE W4950 CRL Wood"s Powr-Grip 8" Vacuum Cup. CRL proudly offers you our Cat. No. W4950, the most popular and safest model of CRL Wood"s hand held Vacuum Cups available on the market today. These specially designed, hand actuated cups operate on a pump system, and create a vacuum under the rubber pad. The pump"s plunger has a red-line to indicate vacuum level at all times. When it shows less than 100% vacuum, simply pump the plunger until you reach the original vacuum pressure without removing the cup from the glass. To release, just depress the release lever on the opposite end of the handle from the plunger. These cups come with a release valve guard to prevent accidental loss of vacuum. Cat. No. W4950 has an 8" (203 mm) diameter vacuum pad, and comes with a molded Carrying Case to protect the cup when not in use..
