Loading Dock Seals: Seal the Gap Between Trailer and Building
Dock Seals are designed to close the gap between your facility and incoming trailers, helping protect employees, products, and building interiors from weather exposure, energy loss, and unwanted intrusions. An unsealed dock opening can create unsafe conditions, increase heating and cooling costs, and expose operations to dust, pests, and moisture. Dock seals provide a dependable solution by creating a controlled, secure loading environment.
Built for high-traffic dock operations, Dock Seals are engineered to withstand daily trailer impact, harsh weather, and temperature extremes. Their rugged construction helps reduce product damage during loading and unloading while improving safety, security, and overall dock efficiency.

Frequently Asked Questions
What's the difference between a dock seal and a dock shelter?
Dock seals use foam side pads and a head pad that compress against the trailer when it backs in, creating a tight seal — ideal for docks servicing consistent trailer sizes. Dock shelters enclose the perimeter of the trailer instead, allowing full, unobstructed access to the trailer opening and accommodating a wider range of trailer sizes. Our team can help you determine which is right for your dock.
What trailer sizes do dock seals fit?
The beveled side pads are designed to seal against standard trailer widths, reducing the effective door opening to approximately 7'4"–7'6". For docks that service taller trailers or a variety of trailer heights, an optional header curtain maintains the seal across different heights.
Should I choose 22 oz or 40 oz vinyl?
22 oz vinyl handles light to medium duty docks well. For medium to heavy traffic — multiple trailers per day, rough trailer conditions, or abrasive environments — 40 oz vinyl offers significantly better abrasion resistance and longer service life. Wear pleats can extend the life of either option on high-contact areas.
Do dock seals really reduce energy costs?
Yes. An unsealed dock opening leaks conditioned air every time a trailer is at the door. By closing the gap between trailer and building, dock seals help retain heated or cooled air, reduce HVAC load, and keep dust, pests, and moisture out of the building.
How do dock seals hold up to daily trailer impact?
Dock seals are built for compression — seamless construction reduces stress points, and the vinyl-wrapped foam pads are designed to absorb daily trailer contact. High-visibility yellow guide stripes also help drivers center the trailer, reducing off-center impacts that cause premature wear.
Need Help Choosing the Right Configuration?
Every dock is different. Our team can help you select the best model, options, and vinyl weight for your facility based on your trailer traffic, dock configuration, and environmental conditions.
