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.

Mounting plates are used for mounting equipment up off the back of an enclosure. Steel Plates are all 3.3 mm (0.13”) thick hot dip galvanized
material. Aluminum plates are 3.3 mm (0.13”) thick material up to and including 304.8 x 304.8 mm (12 x 12”) size. All larger sizes are constructed
of 4.8 mm (0.19”) thick aluminum plate.
Select mounting plates based on inside length and width of box. Order as a separate item immediately following the catalog number of the
box as follows:
Example: Line 1 DTX-181204
Line 2 WYM-1812-1
For mounting plates in smaller boxes than listed, use similar catalog number logic. Example: A steel mounting plate for a DTX-040404 box
would be WYM-0404-1. Pricing will be based upon a WYM-0808-1 price.
