The oyster coupler from Altrad Generation offers a hinged, snap-fit clamping solution for attaching sheeting rails and secondary scaffold tubes to installed standards where conventional couplers cannot be threaded over the tube end. The hinged shell design opens for placement over the tube and closes to form a secure clamp.
Available from Altrad Generation as part of the scaffold fittings range, oyster couplers work alongside scaffold band and plate, limpet clamps, and external hook couplers for complete sheeting and ancillary attachment solutions.

Frequently Asked Questions
Q. What is an oyster coupler?
A. An oyster coupler is a hinged clamping fitting that wraps around a scaffold tube and opens like an oyster shell for placement. It provides a rapid-fit tube clamp for attaching secondary components, sheeting rails, and ancillary tubes to scaffold standards without needing to thread the tube through the fitting.
Q. Where is an oyster coupler used on a scaffold?
A. Oyster couplers are used for attaching sheeting rails, safety mesh supports, and other secondary tubes to scaffold standards, particularly where the tube cannot be threaded through a conventional coupler due to obstruction. The hinge allows the clamp to open for placement over an installed tube.
Q. What tube diameter does an oyster coupler fit?
A. Altrad Generation oyster couplers are designed for 3.2mm and 4.0mm scaffold tube. Check the product specification for load rating and clamping torque requirements.
Q. Is an oyster coupler a structural fitting?
A. Oyster couplers are secondary fittings for sheeting rail and ancillary tube attachment. For structural scaffold connections, use drop forged double couplers or swivel couplers compliant with BS EN 74-1:2005.
