Key Clamp Single Swivel Socket – 33.7mm

Key Clamp Single Swivel Socket – 33.7mm

Create adjustable tube connections with our Key Clamp Single Swivel Socket, designed for use with 33.7mm outside diameter tube. This versatile 33.7mm key clamp single swivel socket allows one tube to pass continuously through the fitting while the end of a second tube connects via an adjustable swivel socket. The swivel provides approximately 85° of movement in either direction, making it ideal for handrails, guardrails, bracing and bespoke tubular structures where fixed-angle fittings are not suitable.

Manufactured from high-quality galvanised cast iron, this durable key clamp fitting provides excellent corrosion resistance for reliable indoor and outdoor use. The swivel mechanism allows the angle to be adjusted before tightening, providing installation flexibility while maintaining a strong mechanical connection.

Compatible with standard 33.7mm outside diameter tube, the fitting is secured using integrated socket grub screws, tightened with a standard Allen key. As part of a modular key clamp system, it enables adjustable tubular structures to be assembled, modified and extended without the need for welding.

This fitting is designed to connect the end of one tube to a continuous tube at an adjustable angle. If your application requires both tubes to terminate within the fitting, our 33.7mm Key Clamp Adjustable Elbow provides the appropriate alternative.
