Mortex 90‑RJCRWN‑AL OEM Roof Jack Crown Assembly The 90‑RJCRWN‑AL is the factory aluminum crown used on Mortex roof‑jack vent systems for manufactured‑housing gas furnaces. This crown provides proper combustion‑air intake and exhaust termination while protecting the vent system from rain, debris, and weather intrusion. Built from corrosion‑resistant aluminum for long service life, it installs directly onto compatible Mortex roof‑jack bases with no modification required.
Ideal replacement when the original crown is missing, damaged, rusted, or no longer sealing correctly.
