The central sleeve is fixed onto the main pipe, while the other sockets connect pipe ends. By tightening the screws, a secure and rigid joint is formed—no welding required.
This design allows:
Fast installation
Easy repositioning
Simple disassembly for system modification
Installation Steps
1. Prepare the Tubes
Cut the steel tubes to the required length and ensure the ends are clean, smooth, and free from burrs.
2. Position the Fittings
Slide the key clamp fittings onto the tubes and align them according to the desired structure or layout.
3. Tighten the Set Screws
Using a standard Allen key, tighten the set screws to securely clamp the fittings onto the tubes.
4. Final Adjustment & Inspection
Check alignment, make any necessary adjustments, and ensure all screws are fully tightened for a safe and stable structure.
