Flush connections between rails and fittings give structures a clean finished look. Use this framing for stair rails, work platforms, and workstations. Slide the rail over a fitting and tighten the included set screw—the fitting grips the rail from the inside.

Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Made of 316 stainless steel, this framing has excellent resistance to chemicals and salt water. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.

Half the weight of steel, this aluminum framing resists corrosion in wet environments. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.

To provide corrosion resistance in wet environments, this framing is galvanized. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.

No need for fasteners—friction holds this framing together. Use press-fit framing and fittings to assemble carts, enclosures, and partitions.

In addition to being lightweight and strong, this plastic framing is nonconductive with good resistance to chemicals and salt water. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Join the rail and fittings with PVC cement (not included) for a permanent bond or drill and connect with fasteners (not included).

Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Drill rails and connect fittings with the included hardware.

Build workstations, conveyors, and shelving for heavy loads. These clamp-on framing rails and fittings are the thickest and sturdiest in our offering. The fittings slide over the rails in one piece. Tighten their bolts to clamp them in place—no machining or welding required.
