During the assembly process, high density polyurethane foam is injected in between the exterior side skin and the interior lining panels, securely bonding them together into a composite structure that out-performs existing technology and provides for easier component repair. With a 4000D-X Composite™, each of the wall components (exterior side skin, logistic posts or interior lining panels) can be easily replaced individually, and localized cuts and tears in either the interior or exterior panels will not affect the structural integrity of the trailer as in traditional composite plate trailers.

Our .019" thick 80,000 psi galvanized steel interior lining panels are pre-painted white for greater light reflection, allowing fork truck drivers to see better, reducing interior damage. The lining panels are "squeeze" riveted to both the outer skin and side posts to form a snag-free, high-strength composite panel providing greater durability. The fully recessed fasteners won’t work loose or contact your cargo.

All exterior side skins are .040" aluminum, just like refrigerated trailers which use the strength of the bonded foam to the interior lining panels to absorb and distribute the side wall stresses. Torture track tested to the equivalent of 2 lifetimes at Utility’s own real-world test track assures durability under extreme conditions.

Our 80,000 psi galvanized steel logistics posts were designed and torture track tested for maximum strength and durability. Their patented Snag-Free™ design provides 101" of inside width and features a recessed area for structural fasteners that keeps them away from your cargo, eliminating snagging damage. Standard spacing of the logistic posts is 12", 16" and 24" centers which increases your cargo securement versatility. Type "A" logistic slots are located at either 8" or 4" vertical centers, depending on model.

A foam-backed, low-profile 80,000 psi high-tensile galvanized steel wearband provides added impact protection, strength, and stiffness.

Reducing maintenance costs and increasing trade values are the primary reasons for Utility’s standard stainless steel rear door frame, including buckplate, corner posts and header. For resistance to dock impact damage, the stainless-steel buckplate features a 3/8" thick lower "bang" bar and light protection bars. Utility’s unique stainless steel rear door frame design provides an industry leading door opening height of 110-1/2" for maximum forklift clearance.

For maximum strength and durability, the integral 27" deep diamond plate threshold is fully welded to both the buckplate and the 24" deep side gussets. The integral threshold eliminates the rotting of floor boards under an "overlay" style threshold plate and provides superior durability and strength. The threshold is supported by two 5-1/8" deep steel channel crossmembers that are welded to the slider sub-frame and the bottom of the threshold plate. Utility’s high-strength dock bumper is fully integrated into the rear threshold assembly and complies with U.S. Department of Transportation (D.O.T.) and Canadian requirements.

The industry’s leading supplier, Hendrickson® provides our standard VanTraax® air ride suspension. Designed to provide load protection as well as driver comfort, the VanTraax integrated axle mounting design reduces fatigue stress on the axles and increases service life. Hendrickson’s Quik-Draw® pin release mechanism is an included standard making re-positioning the slider easier for the driver.

Our hardwood flooring planks are pre-undercoated for 100% coverage to extend floor life, and a weatherproof sealant is applied between every floorboard seam, full length of the floor, to keep the payload dry. For superior strength, the 80K, pre-coated steel crossmembers are attached to the bottom rails with four 3/8" squeezed rivets. Utility-designed gaskets are installed between the outside mounted air and electrical troughs and the bottom rails for added protection from moisture leaks.

For greater strength and lower tare weight, Utility’s uniquely designed aerospace-style wingplates feature collared holes and embossed ribs. Additional durability is provided by formed channel "X" braces. Web stiffeners between front and rear pairs of crossmembers are designed to absorb uncoupling impact.

The entire king pin assembly is 100% coated both inside and out, with a "self-healing" rust-preventive coating for superior resistance to today’s road deicing chemicals. For increased pick up strength, the approach plate is turned up the front wall a full 12" and is supported by six formed, high-tensile steel channels with legs pointed down to give (12) points of contact to the approach plate. Full-length end plates are used to secure the king pin assembly to the bottom rails with 3/8" diameter squeezed stainless steel rivets.

The extruded aluminum, 4-3/4" radius corner posts provide square loading space for full length loads and also lower maintenance costs. Steel "tees" and vertical steel reinforcing end plates are welded to the 12" high approach plate between the (4) 2" deep hat section front wall posts to prevent front wall post damage caused by pallet impacts.

Utility’s uniquely engineered roof structure features a bi-directionally tensioned .040" aluminum roof skin with diagonal reinforcing plates at all four corners and full-length edge-capping strips to prevent moisture entry. The roof skin is supported by epoxy-bonded, 1" deep, anti-snag roof bows. The roof skin is mechanically "crimped" around the top rail edges as an additional safeguard against moisture entry into the cargo area.

The Stemco Platinum Performance wheel end system includes Guardian® HP oil seals, PRO-TORQ® spindle nuts and Integrated Sentinel® hubcaps. The entire system is warranted for five years and covers both parts and labor.

Bendix braking components including spring brake chambers, automatic slack adjusters, SR-5™ Relay Valve and TAB-6 ABS are standard equipment on all 4000D-X Composite™ trailers. Bendix products provide the operator with outstanding performance, and high reliability from matched parts that compliment many new tractors equipped with Bendix components. The simple upgrade to a TAB-6 advanced braking system with roll stability is now a lower cost option that can significantly improve fleet safety.

For easy access, simpler maintenance and less downtime, the gladhands and nose box are externally mounted. The modular, Utility designed, internally grounded main harness is warranted for 10 years. The harness features all soldered connections versus crimped connections and provides 100% plug-in connectors. LED upper clearance lights and stop-turn-tail lights provide up to 10,000 hrs of trouble free service. Lower rear side clearance lights are recessed under the bottom rail to reduce damage and maintenance costs.

Need more interior light? Translucent roof skin from Kemlite is available for increased visibility.

Our 1/2" thick composite panels are available in either PPW aluminum or Stainless outer skins. Both offer greater durability and less maintenance.

Available for both single axle doubles and dual axle vans, reinforced for maximum durability and longer life.

A wide range of roll up doors are available from all manufacturers.

Utility Trailer pioneered the development of lower glare stainless steel rear door panels without sacrificing style and looks. Available on ply-metal doors only.

Utility’s 16,000 lb. capacity all-aluminum, heavy-duty floor provides greater payload capacity and lower tare weight.

For added impact protection, strength and stiffness, this wearband is 10 times stiffer than the base wearband. ID width is reduced by 3/8".

The wide track system is optimal for weight reduction and is available with single-wide base tires and 6" wider air spring centers for greater stability and improved tracking.
