Hanmecson , Model: PRO-V10, 10,000 lb 2 Post Auto Car Lift (4 Arms Only For Parts). This is for the 4 arms pictured ONLY that came off the above listed lift. Please see all 12 of my pictures for a better description. This is just for the 4 arms only and not the lift. The pictures of the lift and model are for Reference Only. The 1 pin that is pictured is not included with the arms. The hole where the pin fits in, is approx 1 1/2" in diameter x 6" tall. See my pictures of the 4 arms only that you will receive. The arms do have paint loss, grease and dirt on them. I have 2 sets available...
