Superior Main Beam. Lower Maintenance.
The two-piece, welded main beam design eliminates
the need for mechanical fasteners by welding on the
neutral axis of the main beam where bending stress is
minimal. Unlike bolted designs, this main beam doesn’t
have fasteners, which eventually loosen, requiring
additional maintenance over its lifetime.

Less Weight. More Freight.
Floor crossmembers weld to the main beam, side rail,
and floor to form a super stiff structure, eliminating the
need for knee braces for a lighter weight trailer and
less maintenance.

Greater Flexibility. More Loaded Miles.
The Lock-Rite™ multi-position tie down system offers
flexibility to either tie down narrow loads to the center
of the trailer or to the outside siderails. This patentpending design also allows the use of either straps or
chains to secure loads. In addition, this flatbed comes
standard with five additional stub crossmembers to
support steel coil hauls. An optional full-length coil
package is available.

Better Highway Visibility.
The enhanced visibility lighting system offers three stop/
tail/turn lights and five dual-function side marker lights.
The side marker lights also function as turn signals for
improved motorist visibility. In addition, the one-piece,
tubular bumper includes an extruded grip surface.
