The internal expanding joint is intended for joining two lengths of 42.4mm outside diameter tube, commonly used in handrail systems, guardrails and metal frameworks. Its design enables installation within the tube, creating a flush finish without external connectors.
This fitting is practical for both new installations and repair work, as it allows sections to be joined securely while maintaining smooth, uninterrupted lines. It is especially suited to jobs where visual appearance and eliminating snag points are important on site.
