Dynabrade 11280 Contact Arm Assembly 1/4x18 in Belts

Product Description

The DYNABRADE 11280 is a contact arm assembly designed as a replacement component for Dynabrade abrasive belt tools. The contact arm serves as the structural interface between the tool body and the abrasive belt, guiding belt tracking and maintaining consistent surface contact during grinding or finishing operations. This assembly is sized specifically for use with 1/4 inch wide by 18 inch long abrasive belts. It is a standard replacement part installed by industrial maintenance technicians, tool repair specialists, and abrasive finishing professionals.

This contact arm assembly is intended for use in abrasive belt filing and finishing applications where narrow belts are required. Narrow belt tools in this configuration are commonly used for deburring, blending, and detail finishing on metal workpieces in fabrication, welding, and maintenance environments. The 1/4 inch by 18 inch belt size suits tight-radius and contour work where wider belts cannot reach.

Key Features

• Designed for 1/4 inch wide by 18 inch long abrasive belts
• Functions as the primary belt-guiding and contact interface on compatible Dynabrade belt tools
• OEM replacement assembly for maintaining tool performance and belt tracking accuracy
• Supports precise surface contact in deburring, blending, and finishing applications

Compatibility

Designed for use with Dynabrade abrasive belt tools that accept 1/4 inch (6 mm) wide by 18 inch (457 mm) long belts. Consult the Dynabrade parts diagram for your specific tool model to confirm fitment before installation.
