The Axia Alloys billet fire extinguisher mount is a work of art. Its aircraft-grade 6061 aluminum and stainless steel components are precision machined for a perfect fit. All contact points are O-ringed so that it will not wear or rattle in even the most demanding off-road environment. Billet mount only; NO fire extinguished supplied. Mix and match any clamp sizes to mount any 3.25" extinguisher to any size tube. Note: Roll bar mounting clamps NOT included.
