The C3SC12128GY is a 12 x 12 x 8 in (305 x 305 x 203 mm) square-faced junction box from the C3SC Series, built with a heavy duty screw cover for electricians, panel builders and OEM engineers who need a sealed wiring box, junction box, terminal box or pull box. It is designed for indoor or outdoor applications where it will be subject to windblown dust or rain.

Seams are smooth and continuously welded, and the box is supplied without knockouts, cutouts or holes, so you place entries exactly where your layout needs them. The enclosure and cover carry an ANSI 61 gray powder coating inside and outside.

The cover is secured by captivated stainless steel screws that thread into sealed wells, and a seamless poured-in-place gasket seals the opening. Per the drawing, the door measures 12.19 x 12.19 in, the opening is 10.63 x 10.63 in, the clear space available on the door is 11.50 x 11.50 in, and the usable depth is 7.86 in.
