Car builders and fabricators, this Allstar Performance tube clamp is exactly what you need for mounting accessories to round tubing! The 1 inch inner diameter fits standard tubing perfectly, and the 2 inch wide design provides plenty of surface area for secure attachment. Made from 1/8 inch thick mild steel, these clamps are sturdy enough for most applications but still easy to work with. Each clamp comes with two 3/8 inch grade 8 bolts and nyloc nuts that stay put once tightened. The 2-piece design bolts around existing tubing without needing to cut or modify anything, making installation super simple. You can weld directly to the clamp plates for permanent mounts, or just bolt them on for removable applications. Perfect for adding mounts to roll cages, frame rails, or any round tubing in your project. The quality is typical Allstar - well-made with clean machining and consistent sizing. Whether you're building a race car, off-road rig, or just need to mount something to tubing, these clamps make the job way easier. They're affordable enough to keep several on hand for various projects too. If you're tired of rigging up makeshift mounting solutions, these professional tube clamps are totally worth having in your toolbox!
