The mating undercut/draw cut butt joints of covers within each row provide adequate strength and stability without the need for cross supports over the opening
There is no limit to the width number of rows that can be used
Covers can be removed for partial or complete access to the opening as required
Ductile Iron Gratings
Modular design – runs are built from a range of standard grates and bolted frame sections to suit any required length
Unrestricted trench access – grates can be removed individually for partial or complete access to the trench
Hydraulic efficiency – grate openings have been designed to prevent the ingress of large harmful debris whilst allowing smaller unobjectionable material to pass through without clogging the grate
Strength and durability – made from ductile iron grade 500/10 for superior strength to weight ratio
Stability under load – frame bar design ensures stable, permanent keying of frame in surrounding concrete
