FRAME TYPES
We recognize that all job sites are different and require varioius options.
To accommodate this we offer two types of frames
TRENCH GRATE SOLUTIONS
USF 6560 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.
BOLT
USF 6800 SERIES STEEL FRAMES
Frames are supplied in 10' lengths.
These frames are ideal for forming on long runs of
trench. Frames are shipped in sets with a spreader
bar welded to angles to give proper width for
required grate. Stud anchors are included to tie into
reinforcing. These frames have tabs and holes to
bolt sections together during forming. Precut final
lenghts and turns are available. Frames can be
supplied with painted or galvanized finish. These
frames are available with steel end plate, if required.
