The H1 Series trailer roof rack set from Vantech is a single set of mounting uprights, bases and a single cross bar that mounts to the upper side of enclosed trailers. The mounting uprights and bases are machine-welded to keep a solid, water-tight seal.
A single roof bar is available from Vantech that is designed to fit to enclosed, pull-behind trailers. Whether its a small, pull-behind trailer for motorcycles, a regular enclosed box trailer, or a six-wheel gooseneck trailer, the range of cargo trailer roof racks fit nearly all enclosed trailer sizes. Cross bar widths are available in six lengths from as little as 42" up to 96". Durable steel side-roof racks are available to hold cargo up to 300 lbs.
The clearance height of the regular H1 trailer roof racks measure at 8-1/2". A taller version is available and measures in at 16". The 16" version allows users to not only use the upper side of the cross bar, but the bottom side as well. Conduit carriers and other materials can be hung from the bottom of the cross bars to double up on storage space.
Mounting bases are drilled into the side of the enclosed trailer and attached with an interior mounting plate. Gaskets are placed in between the mounting plates and trailer to prevent water leakage while the mounting uprights are capped with rubber to prevent wind noise. Drilling is required.
