Wrekin Products, manufacturer of intelligent products for civil engineering, has a patented articulated coupling for its new Highway gully grate range. The design delivers the ideal combination of double-triangular non-rock stability with a captive hinge for easy maintenance and long-term security.
Part of the comprehensive Highway range, the gully grates are designed to be simple for specifiers and users to select as well as far exceeding compliance with relevant standards, including BS EN 124 and HA104/09.

A common alternative is a one-piece, rectangular hinged gully, which offers better security but is less stable in the long term.
The articulated coupling is flexible enough when closed to allow the double triangles to rest naturally, for three-point suspension. When opened, the captive hinges reduce the risk of theft while providing rigidity to allow easy lifting for gully cleaning.
Due to the unique design, hinging is reversible on most sizes allowing the grating to hinge correctly for the traffic flow direction.
The Wrekin Highway Gully is also available in a vast size range of sizes including twin configuration units.
