Dimensions in inches (LxWxH): 9.7 x 9.7 x 3.3 Review: Thankfully have not needed to use the fire extinguisher. 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: 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 - Package Dimensions: 7.874 cms (L) x 16.256 cms (W) x 7.874 cms (H) - Product Type: Battery - Package Quantity: 1 - Country Of Origin: China ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TO64GQ0 | | Brand | H3R Performance | | Customer Reviews | 4.4 4.4 out of 5 stars (62) | | Date First Available | 28 Mar. 2015 | | Item Weight | 522 g | | Item model number | NB300 | | Manufacturer | H3R Performance | | Manufacturer part number | NB300 | | Model | NB300 | | OEM Part Number | NB300 | ## Product Details - **Colour:** Black - **Brand:** H3R Performance - **Material:** Nylon - **Finish type:** Black - **Manufacturer:** H3R Performance ## Images ![NB300 Quick Release Bracket (Extreme Duty) - Image 1](https://m.media-amazon.com/images/I/61NMoM399VL.jpg) ![NB300 Quick Release Bracket (Extreme Duty) - Image 2](https://m.media-amazon.com/images/I/31NSYlp0owL.jpg) ![NB300 Quick Release Bracket (Extreme Duty) - Image 3](https://m.media-amazon.com/images/I/31WzltURdIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***. on 5 July 2025* Thankfully have not needed to use the fire extinguisher.
