Features
- No welding. Bolts tightened with an Allen key lock the joint in place, with no welding or specialist tools.
- Reusable. Undo the bolts and the frame comes apart, so the fitting can be used again in the next display or stand.
- Two finishes. Galvanised suits outdoor use and semi-outdoor commercial settings. Matt black e-coat is for indoor furniture and displays where appearance matters.
- Not for safety rails. Square fittings are not suitable for safety applications such as handrails or guardrails, whatever the fitting name. For those, use round tube with key clamp fittings.
