High Strength Fork Extensions are lighter weight, but just as strong as standard but heavier fork extensions. The high strength material provides extra support needed to lift large heavy objects with a fork lift. A 3/16" thickness and included lifting handle for simple placement of the extension onto the lifting fork. These models are almost 40% lighter than standard fork extensions. 4,000 pound capacity is evenly distributed per pair. A powder coat finish is included to diminish scraps and minimize abrasion during use. Baked-in powder coat finish for added toughness.
