Quick Overview

The R&B Leather Radio Strap is a load-bearing communication system worn diagonally across the torso that repositions a portable radio from an exposed belt to a protected undergarment position, enabling firefighters, EMS personnel, and rescue technicians to maintain radio readiness during IDLH operations.

The strap system is built around a 1.25-inch heavy-duty leather body, a nickel-plated positive-locking adjustment buckle, two scissor-gate scissor snaps that interface with D-rings on the radio case, and an integrated leather microphone loop positioned in the upper third of the strap. Each component serves a distinct function: the leather distributes load to reduce operator fatigue, the scissor snaps resist accidental release under dynamic stress, and the mic loop standardizes speaker microphone placement near the clavicle for consistent transmission during strenuous activity. This is a fielded system, not a convenience accessory.

The deployment protocol requires the radio to be worn beneath the turnout coat outer shell, with only the remote speaker microphone cord routed out through the neck opening or front flap. This configuration shields the radio body from thermal damage, moisture ingress, and impact while keeping the operator's duty belt clear for tools. The strap runs on the non-dominant side, with the top of the radio positioned below the armpit to preserve full range of motion under full PPE.

Readiness is maintained through a mandatory pre-shift inspection of the leather, hardware, and stitching before each use. Service life is condition-based, not time-based. Any strap showing burns, tears, failing hardware, or permanent chemical contamination must be removed from service and replaced immediately.

Field Application Steps

1. ATTACH RADIO TO CASE: Secure the portable radio in its case, then attach both nickel-plated scissor snaps to the upper and lower D-rings on the case. Verify that both snap gates are fully closed and positively locked before proceeding.

2. CONDUCT PRE-SHIFT INSPECTION: Visually and manually inspect the full length of the leather for cracks, cuts, abrasions, or chemical contamination, paying close attention to hardware attachment points. Actuate both scissor snaps multiple times to confirm free movement and positive lock, and check all stitching seams for fraying or unraveling threads.

3. PERFORM INITIAL SIZING WITHOUT PPE: Don the strap over your station shirt or thermal liner, running it diagonally across the torso. Position the radio case on the flank just above the hip on your non-dominant side to prevent interference with tools on the dominant side.

4. ADJUST STRAP LENGTH: Use the adjustment buckle to set the ride height so the top of the radio sits below the armpit. This clearance is required for full range of motion and must be confirmed again after PPE is donned.

5. DON LOWER PPE: Fully don turnout pants and boots before integrating the radio strap into the outer shell system.

6. DON RADIO STRAP OVER LINER: Place the fully configured strap system over your shoulder on top of the thermal liner or station shirt, with the radio seated on the non-dominant flank.

7. DON TURNOUT COAT OVER STRAP: Pull the turnout coat on over the strap so the strap body and radio are completely underneath the outer shell. This is the primary thermal and impact protection step and must not be skipped or reversed.

8. ROUTE SPEAKER MICROPHONE CORD: Before closing the coat, feed the remote speaker microphone cord up and out through the neck opening or front coat flap. Do not trap the cord under the outer shell.

9. SECURE MICROPHONE AT CLAVICLE: Clip the remote speaker microphone to the integrated leather mic loop or a coat mic tab. Target placement is near the clavicle for clear transmission without impeding head movement or SCBA mask seal integrity.

10. EXECUTE FINAL FIT CHECK: Perform a squat, a forward bend, and simulate a hose pull. The radio must not swing freely or restrict movement. Adjust strap length as needed, and consider the anti-sway strap accessory if additional stability is required for the assigned deployment.
