MODEL: Donovan 1125250, 1125800

The Arm-Lok™ from Donovan Tarp Systems is a pneumatic tarp arm locking mechanism that uses your truck or trailer's air supply to automatically lock your tarp system's sidearm securely into place. Securing the tarp arm decreases wear and tear of your tarp system due to bouncing of the tarp arm during transit and increases the life of your tarp system.

The Truck Kit (Part # 1125250) has a complete pneumatic system powered by the truck’s air supply by connecting to existing in-cab air accessories or manifolds or by connecting directly to an air tank/reservoir. The Truck Kit locking mechanisms are opened and closed utilizing a two-position four-way pneumatic toggle valve inside the cab.


The Trailer Kit (Part # 1125800) has an electric over pneumatic system powered by the truck’s air supply by tapping into the trailer's air supply and operated by a solenoid valve. The Trailer Kit locking mechanisms are opened and closed utilizing a four-way electric solenoid valve operated by a toggle switch in the cab.

Ordered 2/22/26, installed2/23/26, had a gritty sound immediately, and should've asked for a replacement then but was just happy to be mobile again, 3/29/26 left me sitting on the side of the road popping starter fuses over and over... not a decent part especially since im now realizing there is zero warranty... do yourself a favor, read the reviews before you buy and dont put money in this sellers pocket
