The Leister™ Triac creates a permanent weld between two pieces of vinyl. Simply cut a piece of material to overlap the damaged area. Heat the vinyl between the two pieces and exert constant pressure with the wide band roller. The finished repair is virtually invisible when using a matching material. The Leister™ Triac features an adjustable temperature control and is powered by 110 volts. Leister™ tools are guaranteed for 12 months against electrical or mechanical failure caused by defective material or workmanship, provided the failure is not the result of misuse.
