Pair of Aluminum ramp plates - previously used with my pickup trucks to transport mowers and snowblowers using 2x8's as ramps. Missing one carriage bolt (bolts are "square neck", 3/8 " x 2 1/4"......probably a good idea to replace all 4 when you purchase the 2x8's) . Plates are in excellent condition. I don't see this style plate on any websites in 2026. They are more costly to manufacture than the "Z-type" plates being sold today. (16f)
