AEV’s 3” Tube Accessory Mount provides a flat and secure mounting surface for attaching a variety of accessories such as auxiliary driving lights or an antenna, to any 3” OD tube. Even though these clamps were designed primarily for installing our 7000 Series LED Off-Road Lights on our JK and HD Ram* Front Bumpers, they can also be used any brush guard with 3” OD tubing and are compatible with both single and double sheer light hardware.AEV Accessory Mounts are manufactured out of an extremely durable, glass-filled nylon material, ensuring these clamps will look good for years to come, regardless of what corner of the world you live in or travel. Installation is very simple, requiring only a single hex key or Allen wrench. AEV Accessory Mounts are sold individually and proudly made in the USA. OFF-ROAD LIGHTS SOLD SEPARATELY.
