	Other sizes and loads rating are available on request.
	Full load ratings definitions appear in SPECIFICATIONS

Features

All frames have been designed to positively key into the surrounding concrete slab (or mortar infill) and feature Mascot's "keylock" system of cast-in frame ties for maximum resistance to deflection.

NON-STANDARD FEATURES

	All framed gratings can be fitted with holding down bolts for the prevention of grate removal or pit access.
	Mascot's hold-down bolts (unless otherwise requested) are high tensile steel Allen bolts.
	If Required, some grates and frames can be supplied in a variety of cast metals including bronze, brass or aluminum. As tensile and compressive strengths vary between alloys, consult your local Mascot Sales Office to provide load rating estimates and costs.
	The provision of grates and frames cast into a concrete surround is also available on request. This includes all load ratings in both standard and "V-Drain" configuration.
	In certain cases, hinge pins can be fitted to allow easier access if regular pit entry is required.

GENERAL

Load ratings in accordance with the AS3996 where applicable.
Many sump and kerb entry grates have been created to withstand specific loads imposed
by other than legally roads registered vehicles, that is road construction machinery or commercial
passenger aircraft, etc.
Please consult with your nearest Mascot Sales Office for more details.
