This all stainless steel double wall constructed universal wall attachment kit provides of method of emitting the combustion exhaust out of your unoccupied generator enclosure for any 1-1/2” ID flexible steel tubing exhaust kits.

The through wall unit is designed for an approximately 4" thick wall.

The exterior exhaust pipe is 3" long with a slash cut end for prevention of weather penetration and a double wall section to pass through the enclosure wall. Interior attachment length of the 1-1/2” exhaust pipe is an approximately 1” long section.

The 5” X 5” mounting bracket has 4” X 4” hole spacing for 5/16" diameter bolts/screws/threaded rod attachment that you supply depending on application. It is formed with a 3/4" air gap to reduce the amount of contact area and also to provide an air gap for cooling between the bracket and the exterior wall. The bracket also has a series of holes on the outside to vent the space between the two walls of tubing. 

All internal facing seams are welded all round to reduce the chance of leakage.

Slotted mounting plates for the inside wall and a u-bolt clamp for flexible steel tubing is also supplied with this kit. 

The pipe can become extremely hot depending on the tubing length, generator size and workload. Provisions must be made to avoid contact with flammable or non-heat resistant materials when attaching to the wall of the enclosure.
