WALCO V60 EH Retaining Screw Prefab Wall Connector

The WALCO V60 EH Retaining Screw Prefab Wall Connector is a concealed connection system designed for accurate and efficient joining of prefabricated timber walls, CLT wall panels, and light-frame building elements. The EH version uses an adjustable retaining screw, allowing the installer to fine-tune the screw position before engaging it into the compact hot-dip galvanized V-shaped bracket.

This adjustability helps correct small layout deviations and ensures smooth seating during assembly. Once aligned, the wall element slides into the bracket in a dovetail-like motion, forming a stable connection capable of transferring wind loads perpendicular to the insertion direction and providing reliable tension resistance.
