Cross fittings for four-way connections in structural support systems.
Structure Fittings Cross Overview
Cross fittings (denoted X-series) provide a four-way intersection in the structural framework. They allow tubes to intersect in both orthogonal directions at a single junction point. These fittings slide onto matching galvanised tubes and are secured by grub screws. The cross fitting is especially useful where multiple frame members need to pass through the same junction. The cross fitting supports modular, scalable frame geometries without welding. It helps maintain alignment and load distribution in multi-axis support grids. The catalogue lists dimensional parameters (H and L) for various nominal bore sizes.

**Materials & Features**
– Cast iron standard, with optional stainless steel versions
– Internally bore-matched to tube outer diameter
– Grub screws for securing positioning once aligned
**Design Notes**
– Each direction should have sufficient tube overlap for structural continuity
– Use bracing to manage bending/torsional loads from multi-direction junctions
– In asymmetrical load cases, verify stress distribution to each leg
– Cross fitting provides flexibility for future frame expansion
Applications
Cross fittings are useful when:
– A support frame must branch in four directions simultaneously
– Intersection of main and cross bracing is needed in a grid layout
– Load paths must diverge symmetrically from a node
– Modular frame extensions are expected in multiple directions
– Continuous structural routing is needed without welding at junctions
