Structure Fittings – Double Tee
Double tee fittings for multiple branching connections in structural systems.
Structure Fittings Double Tee Overview
Double Tee fittings allow branching in two opposite directions from a central tube, effectively forming a “T” in both directions. They slide onto matching galvanised tubes and are secured by grub screws. The modular design allows complex branching without welded joints. Catalog entries include DT25, DT30, DT40, DT50 with specific dimensions for H and L. These fittings are useful in structural grids or lattice supports where symmetrical branching is required.
Specifications
**Catalog Models & Dimensions**
| Cat.Ref. | NB (mm) | H (mm) | L (mm) | |—|—|—|—| | DT25 | 25 | 50 | 55 | | DT30 | 30 | 65 | 70 | | DT40 | 40 | 70 | 80 | | DT50 | 50 | 85 | 95 |
**Material & Design**
– Typically cast iron, optional stainless steel versions
– Internal bore dimension to fit over tube external diameter
– Locked into position with grub screws
**Design Guidelines**
– Ensure the central insertion depth is sufficient for each branch
– Confirm that branching does not impose undue torsion or load imbalance
– Use in conjunction with structural bracing to support bending
– Appropriate for symmetrical frame architectures requiring dual branch support
Applications
Double Tee fittings are suited for structural frameworks needing dual branching, including:
– Symmetrical support grids branching in opposite directions
– Load distribution across two branches from a central member
– Complex frame intersections in glass plant infrastructure
– Modular reconfiguration where two arms must diverge from one tube
– Structural paths that require mirrored branching while maintaining rigidity
