Type DTX boxes must have a minimum of 3-1/2 full threads at all conduit entrances. The “Max. Conduit Size” listed herein indicates the maximum drilled and
tapped conduit entrance which can be machined into the four unbossed sides of a given box to provide these 3-1/2 full threads. If larger conduit openings
than those listed herein are required, bosses can be supplied by us at an additional cost to provide the minimum 3-1/2 full thread requirement. In addition to
the minimum 3-1/2 full thread requirement, the length of thread at conduit entrances must also be at least 1/4”. A 3/8” conduit entrance therefore requires a
minimum of a 6.4 mm (0.25”) wall thickness. For aluminum box and cover, add suffix —A.
