Triangular Guideline Tape

What is Triangular Guideline Tape?

Triangular Guideline Tape (TGL) or "Type II Tape" is a mil spec tape where the cross-section of the tape is of a triangular shape, so that the edges are half as thick as the center.  The silicone tape is marked in the center with a guideline or centerline, so when the tape is wrapped around wire bundles and cables the user can more easily create a uniform wrap.  In this type ii format, the edges are 50% thinner than the middle, and as each successive layer is overlapped onto the previous wrap, the triangles interlock and created a smoother wrap. This uni-wrap style triangular cross-section allows for a smoother and more uniform insulation coating than rectangular format silicone tape.
