Product overview

The 14DCA-WS is the wall strap for 14" DuraVent DuraChimney II chimney, the system listed for the Majestic Ashland 50 wood fireplace. It supports the chimney at regular intervals along an exterior wall. It is a venting support part, not a fireplace.

DuraVent's catalog states wall straps are required every 8 ft on the exterior of the building only.
