TarpMaster® Series electric tarp systems are pre-packaged with selected pre-assembled components designed to fit most industry standard dump trucks and trailers or pups up to 26 feet long. System variations are also available for belly dump trailers and specialty applications including bulk or grapple loader trucks. Tension spring capacity is determined by tarp length. Dump truck features such as cab guard length and height will affect tarp length and recommended options for a proper system fit. For an ultimate fit, we highly recommend you measure your truck or trailer using our How-to-Measure Guides found in our Document Library to calculate tarp length. Quality tarps by Roll·Rite® are available separately.
