Steel retaining strap (loop style*) prevents fork extensions from sliding off forks during use. Baked-in powder coat finish for added toughness. OSHA regulations require that extensions are no more than 150% of the existing fork length. (e.g. 48" existing forks, the fork extension should not exceed 72"). Maximum uniform capacity is 4,000 pounds evenly distributed per pair. To be used with Class 2 and Class 3 forks only.
