SMC NFPA 6 Bar U-Rack Assembly

If you want to start a heated debate among Rappel Rack aficionados just ask the group what style is best, J Racks or U Racks? Both share benefits such as providing the largest range of friction control with a variety of ropes, being great as either a lowering device or on rappel, not twisting ropes and so on. The benefit that people most often attribute to the U Rack over the J Rack is greater strength. This is a fallacy, despite being the common understanding, as the system fails when the rope brakes rather than the device breaking. As a result, both types of racks achieve similar ratings.

U Racks are used in the opposite orientation as J Racks in that the rack is clipped to the harness or anchor at the bend area of the frame with the “legs” pointing away from the user. The U Rack does not facilitate varying of friction by dropping or adding bars as the J Rack does and the U Rack should never be used with less than 4 bars. The 6 Bar version utilizes a single stainless steel Tie-Off Bar and 5 aluminum Brake Bars.

    Features and Benefits:
  • SMC U-Rack assemblies are the only such U-Racks which are UL Certified to the current NFPA standards.
  • U-Rack may be used as either a rappel or lowering device.
  • U-Rack provides for the even distribution of weight between both sides of the rack.
  • U-Rack does not twist rope as can occur when using a Figure 8 type descender.
  • U-Rack may be used with single or double ropes of varying diameters.
  • Different length racks provide wide range of friction and control under varying weights and applications.
  • User may adjust friction by simply wrapping rope around the Tie-Off Bar(s).
  • Stainless steel rack material provides greater strength, reliability and long lasting service.
  • Tie-Off Bars are tubular stainless steel for longer life.
  • Brake Bars are available as aluminum or stainless steel and come in a variety of styles and sizes.
  • Racks & bars may be purchased separately so that the user may have a greater range of set-up configurations tailored to meet their individual needs for non-NFPA applications and as replacement parts.
