Omega Technologies OMDD1F Offset Double-Ended Low Profile Step-Socket Roller Ratchet®, 5-Hex is a unique and time-saving tool that installs 5 sizes of Hi-Lok® or Hi-Lite® collars and contains 7/32”, 1/4”, 5/16”, 11/32”, and 3/8” hex sizes all in one tool. Omega Technologies OMDD Series Wrenches cover most -5, -6, -8, -10, and -12 collars. Omega Technologies Roller Ratchets® were designed as a response for the need of small ratchet wrenches that could be used in tight areas where the swing of the handle was limited by obstructions, and to have a ratchet or tool that would work with very little handle movement. Roller Ratchets® satisfies both of those requirements.
