But the peace of mind of knowing it's there in my classic car, and won't cause more damage to interior, paint, or electronics if I do need to use it (as compared to using a traditional chemical agent extinguisher), is worth the expense. The Extreme Duty mount works exactly as advertising. It's easy to attach to the seat-mounted bracket, and easy to access. I have mine mounted behind the driver seat. Nobody is ever in the rear seat, it's easy to access, and maintains a clean look. Review: Strong, sturdy, perfect fit for off-road rig fire extinguisher. - Great quality and rigid/sturdy. Definitely a snug fit and took a little finesse to get the bolts to line up perfectly on then extinguisher tank, but once it’s set it’s a permanent solution ## Features - Designed to meet MIL-STD-810G - Designed to withstand inertia loads in excess of 27G - Fire extinguisher quickly releases from bracket - Fire extinguisher cannot be accidentally disengaged from bracket - Pull-ring-to-release flag enhances visibility - Fiberglass reinforced nylon construction - Does not obscure fire extinguisher nameplate ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TO64GQ0 | | Best Sellers Rank | #687,654 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #364 in Fire Extinguisher Mounts & Brackets | | Brand | H3R Performance | | Brand Name | H3R Performance | | Color | Black | | Customer Reviews | 4.5 out of 5 stars 66 Reviews | | Finish Type | Powder Coated | | Finish Types | Powder Coated | | Global Trade Identification Number | 00856991001478 | | Included Components | Extreme Duty quick release bracket for 3.0" diam. cylinders | | Item Depth | 7.874 inches | | Manufacturer | H3R Performance | | Manufacturer Part Number | NB300 | | Material | Nylon | | Material Type | Nylon | | Model Number | NB300 | | Mounting Type | Wall Mount | | UPC | 856991001478 | | Unit Count | 1 Count | ## Product Details - **Color:** Black - **Brand:** H3R Performance - **Material:** Nylon - **Finish Type:** Powder Coated - **Unit Count:** 1 Count ## Images ![Extreme Duty Quick Release Bracket NB300 (for 2.5 lb H3R extinguishers) - Image 1](https://m.media-amazon.com/images/I/61NMoM399VL.jpg) ![Extreme Duty Quick Release Bracket NB300 (for 2.5 lb H3R extinguishers) - Image 2](https://m.media-amazon.com/images/I/31NSYlp0owL.jpg) ![Extreme Duty Quick Release Bracket NB300 (for 2.5 lb H3R extinguishers) - Image 3](https://m.media-amazon.com/images/I/31WzltURdIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the Cost -- Easy to Install & Looks Great! *by S***. on July 5, 2025* Thankfully have not needed to use the fire extinguisher.
