Trip Bumper Drive Pro Plows (PAIR of 22686). Sold in pairs, only fits Drive Pro Moldboards. Fits onto a piece of metal 1/4" thick, 1-3/4" wide, 3" long overall. I am sure it could have other uses as well, not even plow related. Which is why dimensions are provided, and a picture of one installed on a piece of scrap steel for reference only.
