Ductile iron hinged double triangular gully grates
A revolutionary design by Wrekin gives the best solution for grate security and high safety for narrow wheel users.
This grate has the unique Wrekin Tri-Way system of captive hinges that combine with a double triangular seating to allow single unit opening with an anti-theft feature. The Wheel-Safe grate design prevents trapping of small narrow wheels in any direction. This gully grate gives safe passage for wheelchair and pushchair users when moving off a pavement and for cyclists on the road the grate prevents wheel trapping and wheel deflection.
Note that for Group 4 compliance grates must have four flanges, whereas Group 3 may have three. TriWay Wheel-Safe offers both Group 3 and Group 4 compliant grate versions.
