The Glassmend Deluxe windscreen repair kit contains all the accessories to do any repair, anywhere, anytime!
The system works using a unique simultaneous vacuum/pressure method. The vacuum pump draws the resin from the surface of the break externally, while the injector forces resin into the break from the point of impact.
This model also comes with the expander bridge for opening the crack up from inside the motor vehicle. It is a very handy accessory, it's like having another pair of hands.
The bridge can be used with or without the vacuum pump.
