KYM Square U-Joint

The KYM Industries Square U-Joint provides a flexible mechanical coupling for manual side-roll tarp systems on dump bodies, grain trailers, and agricultural haulers. Installed between the manual hand crank extension and the top tarp roll bar, it allows operators to transmit rotational force at offset angles when extending or retracting side-roll tarps from the ground.

Key Features

• Flexible Angular Operation: Flexes smoothly to transfer turning motion from hand cranks to roll axle pipes at varying operating angles.
• Non-Slip Square Drive: Features a 3/4″ inside diameter square socket to prevent rounding and slipping under high manual winding torque.
• Heavy-Duty Cast Steel: Durable metal construction resists bending, joint binding, and impact wear during daily field use.
• Corrosion-Resistant Finish: Protective coating guards against rust, rain, road spray, and agricultural chemical exposure.
