The extra heavy duty fork extensions are built to be strong with double walls on the side and full plate on the underside. A fast and efficient way of handling lightweight loads of bulk. The fork blade extensions are invaluable when it comes to loading or unloading material out of the back of pick-up trucks. The fork extensions slide over fork blades and are locked onto fork blades by tightening the two bolts located on the back of each fork extension. They are further restrained by a heel pin, which fits behind the existing fork blades.
