I have a Toyota 5000lbs. forklift and need fork extenders. My 48" long ones were ok if you only move pallets around, but we lift chassis and other odd items and needed the longer length to get all the way through the item for a safe lift or the extension to get out over an item. Initially, was going to make them, but with steel sky high, it was much cheaper to purchase them. I love these extensions, they are easy to take on and off, and work very well. I trust them and would recommend them to all.
