This soft aluminum J-rail is used on Shasta trailers and many canned hams as a drip rail.
It mounts on the wall of the trailer covering up the roof edge that is folded down the wall a bit. The J-rail acts as a gutter. The roll formed profile is soft enough to bow as you install it.
Mill finish. Measures approximately 3/4" high and extends out from wall approximately 1/2".
Pre-punched 5/32" holes are approximately 3-1/2" apart. It should be mounted with stainless screws. We recommend placing a strip of butyl tape behind it and a bead of Trempro 635 as a finish bead along the top after installation.
It comes in 16-foot lengths which can be picked up at our Santa Fe, NM distribution center. But for shipping it must be cut in pieces so that no one piece is more than 94" long, so we send two 94" lengths and do not send the 4" remnant.
We recommend washing the residual tool oil from this roll formed part before installing. Expect some scratches in the material that can be sanded out.
SPECIAL SHIPPING RULES:
Due to its length, this item and other long items like it are shipped together in a PVC pipe to protect them from damage in transit. Unfortunately, at this time we are not able to ship these extrusions outside the United States and they must ship via FedEx.
