The BMS MICRO-RACK was originally designed for the caving community and has become the device of choice for both expedition and recreational cavers in the US. These closed frame racks offer increased strength (see spec. above) and at the same time are almost one half the size of conventional open frame racks. The bars are fabricated from extra-heavy wall stainless steel tubing which yields unequaled resistance to abrasion. Under normal conditions they should supply a lifetime of use. Supplied with an extended top bar with pin (hyper-bar) the BMS Micro-Rack not only increases options for control of descent but also facilitates simple lock offs . The transition from locked off to descent or lower is smooth and easy.
BMS Micro-Racks are available in two frame lengths to accomodate a wide range of rope sizes and loads. They are also available with a second inverted hyper-bar below the top hyper-bar. This modification allows the user to take an additional wrap around the hyper-bars to further increase the load handling abilities of these devices. This modification has been widely accepted in the Fire and Search & Rescue communities as providing a compact and safe alternative to traditional 6 bar open frame racks.

A few individuals I trust and respect to teach me vertical caving recommended this rack as my first one. The advantages are it is lightweight, simple to operate, steel, and cheaper than a full-sized rack. I’ve dropped 3 pits (about 400 vertical feet so far) with it and only had two issues. (1) The instructions show a “soft lockoff” but were too rudimentary for me to visualize. Basically a loop of rope is passed through the bottom and looped around the hyperbar, which is super simple once you know how it’s done. It’s also challenging to do if (2) the rope is stiff or thick and crusted with dirt. On a clean rope rappelling was a breeze, but on a dirty rope I found it difficult to pass the rope through it. There isn’t much room to work with. As the other review stated I can’t imagine doing this with the short version. In any case it is light, compact, simple to operate, and more than capable of securing my trust and ensuring my safety.

I love my microrack. I"ve used one for rappeling underground for probably 10 years now. I bought a short frame version when I needed a WNS-unexposed replacement. I did not notice much difference but when I was teaching my children to rappel I found that they had a much harder time locking off a short frame microrack using caving rope that had become a bit stiff. Now with the long frame version they do just fine.
