Product Overview

The m2® Ratcheting Medical Tourniquet® (RMT) introduced a fundamentally different approach to tourniquet design when it launched in 2002. Where windlass tourniquets require the operator to twist a rod and lock it in place — a process that can be imprecise under stress — the RMT's ratcheting buckle-and-ladder-strap system applies pressure in discrete, micro-adjustable increments with each ratchet click. The self-locking mechanism means the device cannot loosen inadvertently once deployed: there is no windlass to slip, no velcro to fail, and no separate locking step required. This design earned the RMT recognition in a 2025 systematic review published in Advances in Simulation, which noted that ratcheting strap tourniquets performed among the best for lay-responder application success, with the RMT showing performance comparable to or slightly exceeding the CAT in limited trials.

The 1.5" Tactical RMT is the smallest and most compact variant in the m2® product line, designed specifically for military and law enforcement carry. At 4.75" × 1.5" × 2" packaged and just 2.9 oz, it fits directly into standard-issue tourniquet carriers used by U.S. military personnel without modification. The 0.75" ratcheting buckle and short ladder strap pair with 1.5" military-spec webbing. Application instructions are printed directly on the webbing, ensuring correct technique is accessible to any user without external references — a critical design feature for law enforcement agencies or workplaces that may have personnel with limited trauma training.

The RMT system can be applied with one hand and does not require the fine motor precision associated with initial windlass rod placement. In peer-reviewed comparisons involving lay responders (non-medical personnel), ratcheting tourniquets consistently outperformed windlass designs in first-attempt success rates. For operators who prioritize the widest possible band for pressure distribution, the M2 RMT 2" Wide variant provides the same proven mechanism with a 2" band — particularly effective for larger limb circumferences.

How to Apply

1. Slide or wrap the RMT around the affected limb, positioning 2–3 inches above the wound site.

2. Thread the webbing through the ratcheting buckle — the buckle will engage the ladder strap teeth on each increment.

3. Pull the free end of the strap to tighten; the ratchet clicks confirm each increment of added pressure.

4. Continue ratcheting until bleeding stops — the system is self-locking and will not loosen once set.

5. Mark application time on the device and communicate to receiving medical personnel.

Comparison Context

Compared to the C-A-T® Gen 7 and SOF-T®, the RMT's ratchet mechanism eliminates windlass-rod slippage as a failure mode and enables micro-adjustable pressure delivery that windlass tourniquets cannot replicate. The tradeoff is a slightly different application technique that benefits from regular training. For operators already trained on windlass devices, the learning curve is minimal. The 1.5" Tactical version is the lightest and most compact RMT, ideal for covert carry or situations where kit weight and volume are premium concerns.
