Equalizer Visual Vacuum Plunger Cup - JVC192

Today, you see more technicians using vacuum cups to set a windshield than you saw just a few years ago. The most common thing you hear about vacuum cups amongst technicians is that they do not trust them. Well, you can trust these. The Equalizer® Visual Vacuum Plunger Cups are big: at 7" in diameter and each vacuum cup is rated at 90 pounds of lifting capacity. The handles are made of cast aluminum and are attached to the cup by high tensile strength bolts. All of that is great, but most important of all is the highly visible pump vacuum ring. As you pump the plunger to create the vacuum seal the red line disappears and, it warns you that it is loosing pressure when it reappears. Unlike many vacuums these are made for curved glass - yes there is a difference between a flat glass vacuum and a curved glass vacuum.
