Structure Fittings Coupler

The Coupler is a premium structural fitting designed to connect vertical tubes in modular frameworks. These high-strength fittings allow for seamless tube extension without welding or complex fabrication. Ideal for construction, industrial scaffolding, laboratory setups, and pipeline support, our couplers provide adjustable alignment, durability, and easy installation.

Key Highlights:

• Modular Tube Connection – Extend vertical structural tubes effortlessly
• Adjustable & Slidable Design – Ensures precise alignment and flexible configurations
• Durable Material Options – Cast Iron & Stainless Steel variants available
• Grub Screw Fixation – Secure and stable under heavy loads
• Standardized Models – CL25, CL30, CL40, CL50 for NB 25mm to 50mm

How Does a Coupler Work? Step-by-Step Process

1. Select Matching Tubes – Choose vertical tubes matching the nominal bore (NB) size of the coupler.
2. Slide Coupler Over Tube – The internal bore of the coupler slides easily over the external diameter of the tube.
3. Align & Adjust – Ensure proper vertical alignment for the extension or support framework.
4. Secure with Grub Screws – Tighten grub screws to fix the coupler firmly in place.
5. Extend Framework – Slide additional tubes through the coupler to achieve desired modular extension.
6. Inspect & Finalize – Check alignment, rigidity, and load distribution before final use.

Frequently Asked Questions (FAQs)

Q1: What materials are available for couplers?
A: Couplers are available in cast iron (standard) and stainless steel (optional for corrosion resistance).

Q2: How do I select the correct coupler size?
A: Match the nominal bore (NB) of the coupler with the external diameter of your tube for a secure fit.

Q3: Can couplers be used for retrofitting existing structures?
A: Yes, the slidable and adjustable design makes it perfect for retrofits and field modifications.

Q4: Do I need welding for installation?
A: No welding is required; the grub screw fixation ensures a secure and stable connection.
