The Accessory Mount Extender Kit does just what it says it does: adds mounting space to the side of your Accessory Mount. The extra room allows you to mount lots of different lights, electronics, and other mountables. For anyone who likes to have a small blinking light alongside their main light, the Accessory Mount Extender Kit is key. The kit comes with a 15mm extender tube, fitted end cap, a longer stainless bolt and instructions. Get two to extend both ways and maximize your mounts! CNC machined in our shop in Portland, OR, USA.
