Yakima Load Stops/Canoe Bracket

Description

This is a set of (4) old school aluminum and rubber load stops / canoe brackets.  They probably date back to the late 1970s, but they were little used, because I sold the boat.  These have the plastic adapter for Yakima round bars, but if you have a different shaped bar, I bet you can get a plastic adapter to fit your bar and this base.
I bought them for a canoe, but there are lots of other uses.... lumber, ladders, other items you don't want sliding side to side.
The best place I've found for correct information is the Yakima fit site: https://pit.yakima.com/#Fits
