Testex Press-O-Film Tape Extra-Coarse is designed to be used for a range of 1.5 - 4.5 mils.
Testex Press-O-Film Tape consists of foam with a non-compressible backing. The foam side is rubbed into the surface providing a permanent mold of the profile. The Elcometer 124 Thickness Gauge is then used to measure the peak-to-valley height.
