Standard Series -- (RLHTM - - - Series)
Made in a range of stock sizes for convenient adjustment around standard diameters (typically in OEM or other production assembly work).

Liner Series -- (RLHTM - - - L Series)
Identical with RLHTM series except that the single-piece band is extended underneath the adjustment slots to protect silicone or other soft-surface materials.

Multiples Sizes (RLHP - - - Series)



This special series of Hi-Torque clamps offers a greatly expanded working diameter range by adding extra perforations to the band: Eg. RLHP 4 covers working diameters normally covered by RLHTM-500, RLHTM-550 and RLHTM-600. Only 4 sizes covers working diameters from 1-1/4" (32 mm) to 9-1/8" (232 mm).
