U形架在与J形架相反的方向上使用，因为在框架的弯曲区域，“腿” 总是指向远离用户的位置，将支架夹在线束或锚上。 U形架不会像J形架那样通过掉落或增加杆来促进摩擦变化，并且U形架绝不应使用少于4个杆。 SMC设计的4 bar u型机架的好处是具有两个相对的系杆。这为更快的捆绑方法提供了机会 (用户可以像使用船夹板一样在2个销钉之间编织绳索)，并且用户可以在更短更轻的系统上具有更多 “微调” 的摩擦可能性。

附加信息

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.
