The Chief MAC-501B is an "in-wall" accessory for swing arm mounts. The MAC-501 recesses the low profile JWD swing arm mounts in the wall, making them almost flush (1/2" depth) with the wall in the closed position.
- A solid steel "in-wall" box provides secure installation.
- This accessory allows the swing arm to hide in the wall or extend up to 20".
- This mount is an upgrade from the MAC500, it now includes a RACO style junction box and is compatible with the JWDIW.
