Product Specifications

Replacement Corner for Roll-Rite Extreme Duty Tarp Systems

Roll-Rite front-to-back tarping systems use bow tubes, corner connections, arms, and other structural components to position and support the tarp during operation.

The 76805 Extreme Duty corner casting provides a 90-degree connection within compatible tarp bow configurations.

This corner is specifically identified in Roll-Rite parts documentation for Extreme Duty bow assemblies.

For example, the Roll-Rite 76723 Extreme Duty Bow Set includes:

• 2 × Roll-Rite 76805: Extreme Duty 90° Corner Castings

• 2 × Roll-Rite 76814: Extreme Duty 6" Tarp Centering Flanges

• 1 × Roll-Rite 76875: Extreme Duty Wide Bow Top Tube, 103"

These references identify components used in the 76723 assembly. Each component is a separate part of the complete bow configuration.

This listing includes one 76805 corner casting only.

Why Replace a Damaged Tarp Bow Corner?

Commercial truck and trailer tarp systems are exposed to repeated deployment, road vibration, wind, weather, and occasional impacts.

Over time, a tarp bow corner may become cracked, bent, or damaged, affecting the alignment and operation of the tarp system.

Common reasons to inspect or replace a corner casting include:

• Cracked or broken corner casting

• Bent or misaligned tarp bow connection

• Damaged mounting points

• Excessive movement at the corner connection

• Damage from contact with obstacles

• Improper tarp bow alignment during deployment

Replacing a damaged corner casting can help restore the proper connection between compatible tarp bow components.

Inspect the surrounding bow tubes, fasteners, safety components, and mounting points before installation.
