Cylindrical rollers are offered in 7, 10, 15, 20, 30, 36, 41 and 50 mm lengths to measure tapes, bands, films and similar materials. Roller length should not exceed 2x the width of the material being measured. Tension Ranges: Refer to DX2 Data Sheet. NOTE 1: Starting point of low-range instruments will be higher than DX2. NOTE 2: Models using 50 mm roller lengths are supplied with a special heavy-duty bracket and use the DXX model designation. Finger Support: We recommend mounting a finger support for higher tension ranges 
Note:This model does not include a material thickness compensator 
Features
Dual-flanged outer guide rollers with various widths for better filament guide (single-flanged rollers optional, recommendable if the material being measured is wider than the tape roller) Tape rollers with contact surface from 7 mm up to 50 mm are available Roller shifting mechanism ensure easy acquisition of the running material
