5" Keel Roller with Adjustable Arms 300-017267-10

The EZ Loader 5" keel roller assembly 300-017267-10 includes a rubber roller, two adjustable galvanized steel mounting brackets, three bolts, and three locknuts. It is designed for compatible 3" wide trailer tongues, including 3" × 3" and 3" × 4" applications.

The adjustable mounting arms allow changes to roller height, position, and angle to suit the trailer's support arrangement. The rubber roller provides a rolling contact surface beneath the keel to help guide the boat during loading and unloading.

Adjustable Mounting Arms

This assembly uses two adjustable mounting arms to position the roller beneath the keel. The galvanized steel brackets provide corrosion resistance, while the rubber roller helps the keel move across the contact point during launching and retrieval.

Match the roller position to the boat and trailer manufacturer's support requirements. Correct adjustment should maintain suitable keel contact and clearance from the metal brackets and surrounding trailer components.

Fitment Before Ordering

• Confirm that your trailer tongue is 3" wide and matches the assembly's mounting arrangement.
• Compare the listed assembly dimensions, mounting locations, and available clearance with your existing setup.
• Check that the adjustment range places the roller correctly beneath the keel.
• Verify clearance around the hull, winch stand, coupler, wiring, and other nearby components.
• Match the complete assembly and mounting arrangement rather than choosing by roller size alone.

The listed dimensions describe the assembly and do not specify its maximum adjustment range. Final overall dimensions may vary with the mounting position.

Included Hardware

This assembly includes three bolts and three locknuts, along with the two adjustable brackets and roller. Compare the supplied hardware with your trailer's mounting requirements before installation.

Installation and Adjustment

Support the boat and trailer securely before removing or adjusting the assembly. Inspect the mounting area and surrounding components for damage or corrosion.

Follow the applicable manufacturer's installation and fastening instructions. After adjustment, confirm that the roller turns freely, contacts the keel correctly, and maintains suitable clearance throughout loading and unloading.
