4 Bar U 型机架 - SMC

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.

• 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 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.
