USF 6550 Series Cast Iron Frames
Frames are supplied in 2′ lengths. These frames have tabs and holes to attach sections together during forming. The 2′ length allows more flexibility in applications such as, short runs or where there is a crown in the road that must be followed. These frames are available with steel end plate, if required. The USF 6560 cast iron frames are also used when grates are required to be bolted to frames. The 2′ sections make the bolted set more manageable during handling. Security and tamper resistant bolting applications are available. Contact your sales or customer service representative for more information.
