T-REX Tape is formulated with durable, extra-thick, sun-resistant materials to work longer and hold stronger than other utility tapes, in all kinds of weather.

T-REX Tape can be used for simple around-the-house fixes or extreme industrial repairs on a work site.

T-REX Tape consists of three different layers: a double-thick adhesive bringing together a tough, thick polyethylene skin and a reinforced inner cloth layer using an advanced technology called co-extrusion. The aggressive adhesive is melted and pressed through a high-tensile, woven fabric and into the molten polyethylene skin using heat and pressure to lock the layers together. This is what gives T-REX Tape four times the staying power, three times the holding power and two times the bite compared to regular tapes.

This double-thick, super-aggressive adhesive allows the tape to offer superior hold on more surfaces than other ordinary tapes, including rougher and dirtier surfaces in a wide range of temperatures and humidity levels. T-REX Tape also is specifically designed with a thick sun-resistant skin which gives the tape its famed holding power—inside or outside.
