Milbank PT48AL – Frequently Asked Questions

1) Can the Milbank PT48AL enclosure be installed outdoors?
Yes. The PT48AL carries a NEMA Type 3R rating, so it is built for outdoor wall mounting where rain, sleet and snow are a factor, and it has a drip shield top to shed water away from the cover seam. The steel body has a powder coat finish for corrosion resistance. It is wall mount only, not freestanding or pad mount.
2) What are the actual inside dimensions of the Milbank PT48AL enclosure box?
The PT48AL is a 36 x 8 x 12 inch enclosure: 36 inches high, 12 inches wide and 8 inches deep. That tall, narrow footprint suits a run of terminal blocks, a small distribution assembly or a gutter-style pull between devices on a wall where you do not have the width for a square box.
3) Does the Milbank PT48AL come with knockouts for conduit?
No knockouts. The PT48AL ships blank, so every conduit entry gets field-drilled or punched to suit your run. Plan on hole saws or a knockout punch set plus weatherproof hubs or sealing locknuts on the job, since any penetration you make in a Type 3R box has to be sealed to keep the rating.
4) Can the PT48AL enclosure be locked for a tenant or public area?
Yes. The cover has a padlocking provision, so you can add your own padlock to control access, which is what most property managers and utilities want on an exterior wall. The same front cover also carries a sealing provision, so a utility or inspector can apply a wire seal.
5) Is the Milbank PT48AL a hinged door enclosure or a screw cover?
It is a screw cover, not a hinged door. The spec lists one door with no hinge, so the whole front cover comes off when you open it. For frequent access at eye level that matters, since you have to hold or set down the cover; for a one-time termination or a rarely opened pull box it is the simpler, better sealed arrangement.
6) Will the Milbank PT48AL pass electrical inspection for a commercial job?
The PT48AL is UL Listed as an enclosure for mounting electrical equipment, and the Type 3R rating covers outdoor rain, sleet and snow exposure. It is welded steel, formed and spot welded for support. Any field-made conduit openings still need to be made and sealed per code for the rating to hold.
7) Does the Milbank PT48AL include receptacles or a backplate?
It has zero outlets, it is an empty enclosure for mounting your own electrical equipment. Budget separately for any inner panel, mounting hardware, conduit hubs and the devices themselves.
8) Will the gray finish on this Milbank enclosure match the other gear on my site?
The finish is ANSI 61 Gray powder coat, the standard light gray used across most switchgear, panelboards and industrial control enclosures, so it lines up visually with the rest of a typical electrical room or exterior equipment wall.
9) What is the Milbank part number for the 36x8x12 Type 3R screw cover enclosure?
The manufacturer part number is PT48AL. Quote that number to get the 36 x 8 x 12 inch Type 3R steel screw cover in ANSI 61 Gray with no knockouts.
