The Quick Jam is a rock-solid door jammer made for quick, easy repairs. It's made from a strong 1.250-inch carbon fiber tube. The hook attachments are made from stainless steel. The Quick Jam has a push-button slide adjustment nut on each end. The attachment hooks extend thru the middle of a thick rubber bumper to avoid damage and tool marks to your customers' cars.
The Quick Jam is 11" between the hook to hold the door open at an optimal distance.
To use The Quick Jam simply hook the striker and slide the end piece snug, then insert the latch hook into the door and slide snug. Then, if needed, give a twist to both sliding adjustment nuts to desired tightness.
