SMC Rappel Rack Assembly J Frame (or Open Racks) differ from U racks because they allow the user to adjust friction, while under load, by adding or removing bars. This unique feature results in greater control of the rate of descent. SMC J racks formed out of stainless-steel bar stock, and masterfully welded for exceptional strength and durability. These racks are longer and equipped with 6 bars which allow for a broad variation in the amount of friction created. The top bar, which receives the most wear, is larger and constructed from stainless steel and is equipped with a Tie-Off Bar to facilitate tie offs or quickly add extra friction. The remaining 5 bars are machined aluminum. Features and Benefits: Adjust friction by adding or removing bars while under load Brake bars are replaceable May be used as either a rappel or lowering device Does not twist rope, as can occur when using a Figure 8 type descender Meticulously welded eye May be used with single or double ropes of varying diameters Provides wide range of friction and control under varying weights and applications. Equipped with one stainless steel Tie-Off Bar and 5 Aluminum bars for extra friction and control Made in the USA Specifications Model #: NFPA14001 Material: Stainless Steel Frame & Tie-Off Bar, 5 Aluminum Brake Bars Finish: Polished Anodized Dimensions: 14.4" Long Weight: 29.2 oz (828g) NFPA1983 Certified
