The mount is designed to be mounted directly on a roll cage with hose clamps, the optional billet clamps or flat mounted using the predrilled countersunk holes. The small yet sturdy unit is designed to work with a variety of extinguishers via hose clamps or the custom billet clamps available for a 2.5lb extinguisher (3″ diameter) The release pin lanyard will attach on the base hose clamp, the 1.75 billet-mounting clamp or the bolt that would surface mount. Pull the pin, unit swivels apart for fire extinguisher removal. 7″ long 1″ wide 1 1/4″ from mounting surface to mounting surface.
