The configurator walks you through truck class, bed dimensions, and hauling material — then recommends the right semi-automatic system, the level of debris protection you need, and a compatible tarp. No electrical install, no guesswork.

All Pulltarps semi-automatic systems accept the same four tarp materials. Choose by hauling material, not by system.
Spring-assisted operation means there’s no motor to wire, no battery draw, and nothing to short out. Mount it, tension the spring, and go. It’s ideal for trucks without a 12V kit.
You get the same rugged Pulltarps hardware and tarp compatibility at a lower price than an automatic system. The Open 6000M and 9000M are our most economical ways to get a truck covered and compliant.
The operator deploys and retracts the tarp from the ground with a pull rope, so they never have to climb on the bed or step into traffic. Enjoy a safer crew and a faster turnaround than a hand cranked tarp.
Welded 12-gauge steel and galvanized housing options stand up to daily falling-debris punishment. Designed, machined, and assembled in the USA, with same-day parts shipping and a lifetime hardware warranty.
A semi-automatic tarp system uses a spring-loaded roller and a pull rope to cover a dump truck or trailer bed from the ground. The operator pulls the tarp out over the load, and the spring tension stored in the roller retracts it on the way back. There’s no electric motor and no in-cab switch, just spring assistance that does most of the work, so no one has to climb on the bed.
Automatic systems are electric and in-cab controlled — fastest to deploy, best for high-cycle Class 7–9 operations. Semi-automatic systems are spring-assisted and ground-operated with a pull rope — lower cost, no electrical install, and still no climbing. EZ-Fit kits are bolt-on solutions for smaller landscape and work trucks. See the full comparison.
No. Semi-automatic systems are entirely mechanical — spring tension does the work, so there’s no motor, no battery draw, and no 12V kit to install. That makes them a good fit for trucks where adding electrical isn’t practical or where you want the lowest-maintenance option.
When paired with a properly sized tarp, Pulltarps semi-automatic systems meet or exceed federal load-covering requirements and the load-covering rules in all 50 states. View state and federal tarping regulations.
Pick by falling-debris protection and bed length: the welded-steel SuperShield 9500M (up to 40ft) and 8500M (up to 18ft) for the harshest debris, the galvanized Steel Protector + (28ft) and Steel Protector (18ft) for balanced protection, and the open-frame Open 9000M (30ft) and 6000M (16ft) where debris isn’t a concern. Use the configurator to match a model to your exact truck.
