FE Series fork extensions by Vestil feature all-welded steel construction with baked-in powder-coated finish and offer a uniform capacity of 4000 lb. Their FE-4, FE-5 & FE-6 Series have cast steel tips and FE-7 & FE-8 Series have tapered cut front end. They are used for providing extra support needed to lift long / large objects with a forklift. These units are available loop style extensions that have steel retaining straps to prevent them from sliding off forks during use and pin style extensions that have pins to be reinserted behind the heel of the fork to secure them with the fork. These extensions are made for use with Class 2 & 3 forks only and are designed in compliance with OSHA regulations (extensions should be no more than 150% of the existing fork length). Raptor Supplies offers a complete range of FE-4, FE-5, FE-6, FE-7 & FE-8 Series fork extensions in loop & pin style.
