7.5' Wide Enclosed Construction Trailers

the Superior Strength & Style of Our 7.5' Contractor Trailers.

Our 7.5′ wide all aluminum construction and jobsite trailers have quickly become a hit with builders and contractors! Perfect for those of you who don’t want an 8′ wide trailer but find the 7′ wide version a little too narrow; the 90″ interior width seems to have struck a happy medium. All of our construction trailers are built on fully welded heavy duty all aluminum frames to make sure they’re ready for your day-to-day operations so you and your crew can get to work.

All of our trailers have screwless sides to make sure your lettering or graphics look their best and consider adding roof racks and the front ladder for the ultimate in versatility.

All this with the same great standard features you’d expect from PROLine: side access door, choice of rear ramp door or cargo doors, aluminum stoneguard on the front, LED lights, multiple interior lights, tongue jack, and rugged 3/8″ finished interior walls are just some of the standard features on our all aluminum construction trailers.

Rugged Aluminum Frame

Our aluminum trailers are built to last, starting with rugged main tubes and fully welded joints. We know what types of roads our trailers are dragged over when they leave our facility and our trailers are ready for them.

Quality Trailer Parts

A strong frame is only as good as the components to support it. This is why we use only the best of parts on our aluminum trailers like galvanized Dexter torsion axles, high quality radial tires, LED lighting, and self-adjusting brakes.

2.5x Stronger Roof

Our roofs are built with rugged 1″×2″ aluminum tubes on 16″ centers. That means a roof nearly 2.5 times stronger than many other trailers on the market. We tend to get a lot of snow in New Hampshire, our trailers are ready for it.

Attention To Detail

Every trailer we build is checked and double checked before it leaves our shop. We want to make sure our trailers are looking their best with screws lining up, lines cut straight, doors installed tight, and every trim screw properly located.
