Overview
The H3R Performance BMR12B is a brushed dual clamp roll bar mount for 1-3/4 inch roll bars. It combines with band clamps for 2.5 lb fire extinguishers, and H3R describes its quick-release billet design as accepted by most race-sanctioning bodies and clubs.
Select the band clamp size before choosing between a flat surface mount and a roll bar mount, since the parts are meant to be paired.

Pairing mounts and clamps
A dual clamp mount grips the roll bar at two points, which spreads the load and keeps the extinguisher steady on rough terrain. The mount and band clamp work as a pair, so confirm both are the right size before you buy either one. Quick release designs are convenient, but they still need to lock firmly, so test the latch with the bottle loaded before every trip.
Billet parts are solid and resist bending, yet the bolts and clamp hardware can loosen under vibration. Check fasteners after the first few runs and before each event, and tighten them to the level the fastener requires. Replace any clamp with a cracked or worn lip. Keep the brushed finish clean and dry, and store a spare set of clamp hardware in the vehicle so a lost bolt does not leave the bottle unsecured.
