In-wall box for THINSTALL swing arms

The TA500 is a large in-wall enclosure that lets a THINSTALL swing arm sit flush with the finished wall. It supports displays from 30 to 58 inches and carries a maximum load of 125 lbs. Installers use it to hide the mount mechanism while keeping full articulation.

Check wall cavity and mount compatibility

Verify the cavity can accept the overall dimensions of 21.75 inches high by 34.00 inches wide by 3.96 inches deep. The box is designed only for TS525TU and TS325TU swing arms; other models will not fit. Confirm the wall structure can bear the combined weight of the box, arm and display.

Steel construction with integrated cable knock-outs

The black steel box includes large conduit and single-gang knock-outs for clean cable routing. A black trim kit covers the rough opening for a finished look. At 42 lbs shipping weight, the unit requires secure anchoring to studs or blocking during installation.

Questions about this item

What is included with the TA500 and what must be purchased separately?

The box includes the in-wall enclosure and a black trim kit. A compatible THINSTALL swing arm such as the TS525TU or TS325TU is required and sold separately.

Should I choose the TS525TU or TS325TU swing arm for this box?

Both models are listed as compatible. Select the arm that matches the screen size and feature set you need; the box accepts either.

How does the 125 lb weight capacity translate when the box is installed in a wall?

The 125 lb rating applies to the complete assembly when mounted to structural supports. The 42 lb shipping weight reflects the box and trim kit alone.
