Cross Fittings — Kite Frame Connectors
Injection-molded cross fittings designed for kite frame construction and structural maker builds. These four-way connectors join tubes at the cross point — a critical junction in many kite frames. Available in four size combinations to match common tube diameters, with a 3mm spine rod running through all variants.
Available sizes (spine rod × spreader tube):
- 3mm × 4mm
- 3mm × 5mm
- 3mm × 6mm (currently out of stock)
- 3mm × 8mm
Why these cross fittings?
- Precision injection-molded for consistent fit, repeatable assembly and toughness
- Lightweight at 5–7g — adds negligible weight to the frame
- Four-way design locks spine and spreader tubes at 90° for clean, rigid joins
- Compatible with Exel pultruded carbon rods (3mm) and carbon or fiberglass tubes
- Ideal for scratch-built kites, replacement parts, and STEM kite project kits
Common uses: Stunt kite fittings, diamond kite spine/spreader joins, cellular kite frame junctions, and maker/STEM kite builds.
