S-420 Rigid Frame Dock Shelter by Serco


The Serco S-420 Series rigid frame dock shelter is designed to accommodate a wide variety of door and vehicle sizes, while providing full-width access to the back of the vehicle.

It features steel supports that protect the frame from off-center trailers, along with flexible fiberglass stays that ensure the head and side curtain pressure is maintained on the trailer body. Proper water drainage is ensured with the help of a head frame covered with translucent fiberglass with 2-inch side-to-side rake.
