Tie Down Engineering 86419 Black 5 Inch PVC Ribbed Wobble Roller Kit, 7/8 In and 1-1/8 In Shafts

The Tie Down Engineering 86419 is a black, 5 inch PVC ribbed wobble roller kit built to center and support a boat's hull as it is loaded onto or launched from a trailer. The ribbed surface of the roller is designed to grip the hull more securely than a smooth roller, helping reduce slippage during loading and unloading, while the roller's cushioned, wobble-style construction absorbs shock and impact so the hull is not scuffed or dented against trailer hardware. Because a wobble roller pivots and conforms to the shape of the hull as the boat moves across it, this roller set is especially useful for shallow launch ramps and low-water conditions where fixed trailer bunks are harder to use.

This kit is intended as a replacement roller set for a trailer that already has a wobble roller assembly installed; it is not a complete roller arm or bracket assembly. It fits shafts of 7/8 inch and 1-1/8 inch, and the kit includes two washers, two bushings (sized for each shaft diameter), and two hog rings needed to mount the roller. The 86419 is the black colorway of this 5 inch roller; the same roller is also offered in an amber finish under a different part number.
