Deflector Panel Installations
for LTL Cargo Trucks and Semitrailers with exposed I-Beam or C-Channel Cross-members
For class 6-8 box truck and semitrailers with exposed cross-members, a set of panels attach directly to 3-4 inch tall cross-members (I-Beams or C-Channels) spaced around the industry standards 12-13 inches apart, directly in front of the headwind-exposed rear wheel set. (Please confirm your exposed cross-member configuration.)
Made of conventional trailer skirt thermoplastic in either black or white, Upper Wheel Deflectors properly installed can offer years of worry-free performance. And aluminum components together with zinc-coated clamps resist corrosion. A set of panels can be easily assembled and installed on a truck or semitrailer with exposed I-beams in 20-30 minutes. And the vertical position of the deflector panels can be adjusted for either the typical 5-6" top tire clearance on class six box trucks, or for the 3-4" typical tire clearance on most semitrailers.
I-Beam Clamped Installations: Using I-Beam Clamps
For I-beam cross-member installations, a first option includes zinc-plated I-beam clamps which attach directly to 3-4 inch tall I-beams spaced approximately 12 inches apart. Alternatively, a second option replaces beam clamps with a bolted arrangement. Each I-beam is drilled for a single 5/16" thru-hole for a bolted attachment of each panel assembly directly to the respective I-beam leg. This option includes I-beam leveling washers for a secure permanent attachment to the I-beam cross-members.
I-Beam Installations: Drilled & Bolted
For C-channel cross-member installations, clamped are not recommended. Instead, each C-channel is drilled for a 5/16" thru-hole for a bolted attachment of each panel assembly directly to the respective C-channel leg. This option includes ring washers for a secure permanent attachment to the C-channel cross-members.
