Arlington Industries' Box
Arlington Industries’ FN101FX single-gang, nongasketed vapor box for devices features a nail-on installation to stud in new construction. It protects against air infiltration and is made of plastic. It fits single 1/2- or 5/8-in. drywall. It does not include gaskets, but it meet requirements of NEMA OS-4 when the installer caulks around NM cable.
