Boat owners, if you're fixing or building a bimini top (that sun shade canopy on your boat), these jaw slides are crucial hardware. They're made from marine-grade 316 stainless steel, which is super resistant to saltwater corrosion – way better than plastic or nylon fittings that can crack. Each jaw slide has an internal diameter of 1 inch (25.8mm), so they fit standard 1-inch outer diameter round tubing perfectly. They've got two M6 screws on the side to really clamp down and secure the tube, plus a 1/4-inch bolt hole for a pin. They come in a pack of two, and you even get an L-shaped hex key for tightening the screws. They're polished to a nice finish, so they look good and work smoothly. Use them to connect tubes in your bimini frame. They're tough, built for harsh marine conditions, and a direct upgrade from flimsier materials. If you're doing boat maintenance or a DIY canopy project, these are reliable pieces you can count on. Just pair them with the right end caps (like their matching product B0B4FPSW5N) for a complete setup.
