H3R's fully adjustable fire extinguisher seat mounts install easily in most vehicles, attaching to the seat rail bolts or above the slider of the driver or front passenger seats. Not only does this put the extinguisher at your fingertips, but it avoids the need to drill mounting holes into your vehicle. Available in lightweight, durable aluminum construction this product accepts all H3R Performance fire extinguisher billet aluminum and standard brackets. Patent pending. Please note that mounting to seat rail bolts may restrict forward seat motion on certain vehicles. Mounting to seat slider (where possible) maximizes range of seat movement.
