Coupler fittings for connecting structural tubes and components.
Structure Fittings Coupler Overview
Coupler fittings are used to join two vertical structural tubes when additional length is needed in the support framework. These fittings slide over matching galvanised tubes and are fixed in place using grub screws. The coupler enables modular extension and alignment without the need for welding or complex fabrication. Catalog references show standard models such as CL25, CL30, CL40, and CL50—indicating nominal bore (NB) sizes and their associated dimensions (H and H1). Because the fitting is slidable and adjustable, it supports flexible design modifications and makes field adjustments easier during installation or retrofitting.
Specifications
**Available Models & Dimensions**
| Cat.Ref. | NB (mm) | H (mm) | H1 (mm) | |—|—|—|—| | CL25 | 25 | 150 | 200 | | CL30 | 30 | 150 | 200 | | CL40 | 40 | 150 | 200 | | CL50 | 50 | 150 | 200 |
**Material & Finish**
– Generally cast iron construction, with optional stainless steel variants
– Slidable internal bore matching external tube diameter
– Fixed in place by grub screws once aligned
**Design Constraints & Notes**
– Coupler must match tube NB size for proper fit
– Overlapping length must be adequate to maintain rigidity under load
– Use in assemblies where vertical alignment and extension without stress on glass is critical
Applications
Coupler fittings are specifically useful in structural support systems where extension or seamless linkage of vertical members is required, such as:
– Extending the height of glass column supports by joining multiple tube lengths
– Facilitating modular upgrades in existing glass plant structures
– Adjustments during alignment and leveling without disassembly
– Situations demanding minimal thermal or mechanical stress on glass components
– Retrofit installations requiring flexible support adaptations
