Equalizer® Two Vacuum Cups - ESM911
Each Equalizer Vacuum Cup swivels up and down approximately 30° to fit radically contoured glass. Made of super strong, fiber-reinforced plastic with rubber gripping cups. Simply set the vacuum cups in place, seat them firmly against the glass, and push the thumb latches down to engage the vacuum. You can then comfortably and safely lift any piece of auto glass. Designed for automotive use, we do not recommend these for plate glass. Do not lift in excess of 75 pounds.
