Arborist-specific: Climb Right aluminum spurs are lighter than steel climbers while maintaining high strength. Made by Spyder Manufacturing with a straight shank from tempered aluminum. The bottoms of the climbers are textured for better grip when walking on tree limbs. The gaffs are made in Spyder’s new Quick Change style, with a two-screw design that lets you switch or replace gaffs quickly. The top screw is fully threaded through the gaff, giving the operator a visual guarantee the gaff is completely tightened to the climbing stirrup. Climb Right aluminum spurs are made in the USA. Add your own straps and start climbing in these unique spurs. Will work with L Pads, T Pads, Super Climber Pads, Soft Cushion Wraps, or the new Ultra Light Pads, and universal straps.
