A standard extension follows the line of the trailer (curbside or roadside).
A wrap "turns the corner" around the front or rear of the trailer. It terminates on the opposite side.
The photo shows a "rear extension wrap" turning the corner on the lift gate end of a semi.
Standard canopies mount onto the Curbside or Roadside of the trailer.
A Roadside mount goes on the driver's side of the trailer, facing the street. Sometimes referred to as a street side mount.
A cantilevered style frame or canopy uses horizontal braces and creates unobstructed clearance under the canopy. This style typically does not have skirts. Also called a Suspended Canopy.
The frame rises above the trailer roof line before sloping to outer eave. Used when trailer is too short to provide proper slope for watershed. Available on Cantilevered and Fully Enclosed canopies.
Even short trailers such as goose-necks can accommodate our canopies. You simply add a "rise above" to create an elevated rear eave. The photo shows the "open frame" method (left end) and "tilt-up panel" method (right side).
An extension adds to the length of the canopy by extending past the trailer end(s).
The two most common styles are tapered (standard) and straight back rafter.
The tapered style has a diagonal rafter extending from the trailer to the outside corner. The straight back style follows the same slope as the main canopy.
Extensions can...
The frame projects horizontally (parallel to the ground) before sloping to the outer eave.
Used when trailer has tall doors or slide-outs that may need clearance before sloping.
