The Key Clamp system is professionally engineered for maximum versatility and ease of use across industrial and commercial environments. To install, simply secure the fittings onto the standard 48.3mm tube using a hex key (Allen wrench) to instantly create a rigid joint with impressive stability and load capacity.

This innovative approach is suitable for permanent installations and temporary structures alike, such as scaffold tube clamps and queue management systems. Unlike traditional welding, these fittings are fully modular and reusable, allowing you to easily disassemble, modify, or relocate your structure as your needs evolve. We stock a comprehensive selection of components - including the 101D Short Tee, 125D 90Β° Elbow, 132D Railing Base Flange, and the 143D Handrail Bracket - covering every joint required for complex key clamp railing and safety applications.

1. What size tube do these fittings accept?

These fittings are designed to accept standard structural tube with an outside diameter (OD) of 48.3mm. This size is commonly known in the industry as Size 8 and is the same size used for standard scaffolding tubes. This ensures guaranteed compatibility and maximum load performance.

2. Do I need special tools or welding experience to assemble structures?

No. The entire system is designed for no-weld assembly. All you need is a standard hex key (Allen wrench) to tighten the grub screws (set screws) on the fittings. This allows for quick, safe, and clean assembly by anyone without specialised training or hot works permits.

3. How strong are the joints, and what kind of weight can they support?

When properly tightened, the fittings create extremely secure and rigid joints suitable for heavy-duty applications. They are robust enough to construct permanent safety features like handrails, guardrails, and industrial racking. The strength of the final structure is determined by the load rating of the tube, but the fitting joint itself provides exceptional axial and slip resistance.

4. Are these fittings suitable for permanent outdoor use?

Yes. All fittings are made from heavy-duty galvanized steel. This coating provides superior protection against rust, corrosion, and weathering, making them ideal for permanent external applications such as exterior safety railings, outdoor signage, and barriers in harsh industrial environments.

5. Can I dismantle and reuse the fittings if I need to change my structure?

Absolutely. A major benefit of the Key Clamp system is its full modularity and reusability. Unlike welded structures, you can easily loosen the grub screws with a hex key, dismantle the structure, and reuse all the fittings and tubing to build a completely new configuration elsewhere.
