Friction tape (aka grip tape) used between the backglass and the metal lift channel of older Bally, Williams and Stern pinball machines.
If you have a loose fitting lift channel, using two 2" strips of this tape will tighten up said fitment. One 1-foot roll is enough product for approximately 3 backglass lift channels.
Comes in 1-foot sections; adding *1* to your cart will get you one 1-foot section, adding *2* to your cart will get you two 1-foot sections, etc.
