Constant-Torque® Marine Worm Gear Clamps use a patented Belleville spring mechanism to automatically adjust the clamp diameter in response to changes in environmental and operational temperatures. The 9/16" wide Aero Seal design is for smaller diameters and is torque rated for 30-70in./lbs. The 5/8" wide Heavy Duty design is for larger diameters and is torque rated 50-125 in./lbs. Both designs are marine quality stainless steel, and are listed here for your convenience.
