An ATG tape adapter is used with ATG adhesive applicator guns. These ATG adapters allow you to use a narrower width refill roll in an ATG dispenser that's been designed for wider width rolls. ATG applicators and these adapters are used to apply Adhesive Transfer Gun (ATG) tape. Using an applicator gun allows easy application, and the applicator automatically winds up the tape's liner as it is used. This greatly simplifies the process of using ATG tape.
