Just right for SWAT teams, climbers, cavers, and sport rappelers, the slightly more compact design of the Rappel 8 offers superb control on smaller rope. Machined from a 12.5-mm (1/2-inch) aluminum plate and utilizing CMC’s superior proprietary finish for even longer wear resistance, the Rappel 8 contains almost twice the material of other small 8s, providing better heat dissipation. Because the Rappel 8 was optimized for use with NFPA Technical Use rope 9.5-11 mm (3/8-7/16 in), it is certified Technical Use.
