Super Duty Shur-Lok®

With proper tension, the tarp stays tight no matter your length of trailers. The standard crank is direct drive 1:1 and lets you roll the tarp standing safely on the ground. An upgrade to electric is available, as are more SMARTrailer™ options.

Our standard easy-off tarp stops enable fast, easy tarp removal. An upgrade from our standard stretch cord return to our cable return features a non-stretch cable with a heavy-duty internal tension spring-and-pulley system.

The patented design of our Wil-Slip™ joint pull-out crank assembly allows crank arm and U-joint to slide forward, bypassing hinges and clearing rear doors. This upgrade, ideal for open-top vans, Convertahoppers, belted floor trailers and “barn door” trailers, uses deeper caps that, if aluminum, are made of a heavier alloy. All require a cap depth of 26 inches.

Shur-Co® offers a wide variety of tarp fabric choices. This year, we are pleased to introduce DiamondCore™, a premium fabric that provides added substance, increased endurance and unparalleled abrasion resistance. Unlike diamonds, no tarp lasts forever, but upgrading to DiamondCore™ offers you rock-solid quality backed by a 24-month warranty - the best in the industry. It is currently only available in black.
