Rear Impact Guards
DOT-compliant rear impact guards are engineered to absorb impact and enhance safety during rear-end collisions. Their robust construction provides dependable protection without adding unnecessary weight.
Corner Caps
Heavy-duty aluminum corner caps protect high-impact areas from dock damage while maintaining the trailer’s structural integrity and clean appearance. Designed for longevity, they help reduce maintenance costs over the life of the trailer.
Top Slide Rails
Reinforced top slide rails add critical strength along the roofline and provide secure mounting points for roof components. They help maintain trailer squareness and durability in demanding over-the-road use.
Side Panels and Flat Sheets
Smooth, durable side panels and flat sheets offer excellent cargo protection and an ideal surface for graphics or fleet branding. Built for rigidity, they resist dents and flex under load.
Solid Oak Interior Flooring
Solid oak interior flooring delivers exceptional strength and wear resistance for forklifts and heavy cargo. It’s a proven choice for maximizing floor life in high-cycle operations.
Bottom Slide Rails
Bottom slide rails reinforce the lower structure of the trailer, protecting against road debris and dock contact. They also contribute to overall frame strength and long-term durability.
King Pin Lock
The king pin lock system is built for secure, reliable coupling with the tractor. Precision-machined for strength and consistency, it ensures confident hookups and safe miles ahead.
Roof Panels and Roof Bows
High-quality roof panels paired with precision-engineered roof bows deliver superior load support and weather resistance. This design minimizes leaks while standing up to snow load and daily stress.
