BMS Rescue Racks

The BMS Rescue Racks

are designed for the professional rope rescue user. Constructed entirely of high strength stainless steel these racks standup to the harshest of conditions. The closed frame yields a device many times stronger than it's open frame counterparts and the extra heavy tubular stainless steel bars stand up to severe abrasion. These characteristics yield a descent control device with a service life many times longer than their competitors. Offered in two frame lengths with either four or six bars, both of which easily accommodate two 1/2" ropes. Top bars are of the double hyper-bar design which provides added load control options and simple and secure lock offs for either 1 or 2 ropes allowing independent control over both ropes. A slight variation on the 4 bar Rescue-Rack uses a second double hyper-bar in place of the third bar. This allows the operator to add extra wraps around the hyper-bars to increase friction to maintain control under demanding rescue conditions. All models are easily locked off by passing a bight of rope through the frame and looping it over the hyper-bar.

BMS Micro-Racks

From left to right:  1. Dual Hyper-Bar Long Frame,  2. Dual Hyper-Bar Short Frame,  3. Single Hyper-Bar Long Frame,  4. Single Hyper-Bar Short Frame

BMS Micro-Racks

were originally designed for the caving community and have become the device of choice for both expedition and recreational cavers in the US.  These closed frame racks offer increased strength (see spec. below) and at the same time are almost 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 (see Rigging Configurations below).  The transition from locked off to descent or lower is smooth and easy. BMS Micro-Racks are available in two frame lengths (specs below) to accommodate a wide range of rope sizes and loads.  They are also available with a second inverted hyper-bar below the top hyper-bar (see picture above).  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.

  • New Super Tough Urethane Rollers
  • Corrosion Proof Aluminum and Stainless Steel Components
  • Permanently Lubricated Axels With Teflon Grease
  • Easily Secured In Place with 8mm Accessory Cord

When inverted (rollers down) can be used to move backboards/litters and other materials more easily in confined spaces (4 Roller unit recommended for stability).

Used by Fire Departments as hose rollers to ease movement of hoses through structure openings reducing drag and easing deployment (4 Roller unit recommended).


2 Axel Unit(one roller/axel) :  13.5” L x 6” W x 3.5” H Weight:  1 lb. 14 oz. (0.85 kg.)

300 lb. capacity when used in inverted position (rollers down).

BMS Cata-Roller II

BMS Cata-Roller II

Edge Roller For Two Tensioned Lines

The new BMS Cata-Roller II allows users edge protection for two lines under tension.  The concept originated with an inquiry from Hubert Biggers of ACTSAFE needing a system that would allow two tensioned ropes to move independently from each another over an edge.  Users of Twin Tensioned Lines* will find the Cata-Roller II greatly simplifies rigging while yielding superior edge protection.  This is accomplished by having two independent rollers on each Cata-Roller Axle.

  • New Super Tough Urethane Rollers
  • Corrosion Proof Aluminum and Stainless Steel Components
  • Permanently Lubricated Axels With Teflon Grease
  • Easily Secured In Place with 8mm Accessory Cord


2 Axle Unit (2 rollers/axle):  13.5” L x 7” W x 3.5 H” Weight:  1 lb. 13 oz.

4 Axle Unit (2 rollers/axle):  25.5” L x 7” W x 3.5 H” Weight:  3 lb. 10 oz.

*Belay and Main Lines are both kept under tension to avoid any slack in the system should a component fail allowing the rescue load to drop a minimal distance.  Our Belay-Spools offer an easy solution by easily maintaining tension on two ropes further simplifying rigging requirements.
