B-LINE WMHK-04 – Frequently Asked Questions

1) What is the B-Line WMHK-04 used for on an electrical enclosure?
The WMHK-04 is a lock latch and handle insert for Eaton B-Line Type 4 and Type 12 premier wall-mount enclosures. It is the handle assembly that goes into the enclosure door, and it is an interchangeable padlock, key-lock and no-lock handle, so the same insert covers all three securing methods rather than you buying a separate handle style per door.
2) Does the WMHK-04 enclosure handle lock with a key, or do I need a padlock?
Either. The insert is key-locking, and it is also built to take a padlock, with a no-lock option if the door does not need securing. That means one part number covers a plant where some panels are keyed and others are padlocked for lockout.
3) Is the B-Line WMHK-04 handle insert UL Listed?
Yes, the WMHK-04 handle and lock latch carries a UL Listed marking, which matters if the enclosure it goes on has to hold its Type 4 or Type 12 rating on an inspected install.
4) What size is the WMHK-04 handle insert, and will it clear the cutout on my panel door?
The insert measures 2.499 in by 2.175 in by .989 in and weighs .39 lb. Check those three numbers against the existing handle opening in your door before ordering, since it is sized for the Eaton B-Line premier Type 4 and Type 12 wall-mount enclosure prep.
5) Can I use the WMHK-04 on a washdown or oil-tight enclosure?
Yes, within its rated families. It is made for premier enclosures rated Type 4 (hosedown and driving rain) and Type 12 (dust, dirt and dripping non-corrosive liquids), so it suits washdown and oily industrial areas where the enclosure itself carries those ratings.
6) I need to standardize enclosure handles across a facility with mixed padlocked and keyed panels. Does one part cover it?
One part does cover it. Because the WMHK-04 is an interchangeable padlock, key-lock and no-lock handle, MRO stores can carry a single insert for every premier Type 4 and Type 12 wall-mount enclosure on site instead of stocking three variations.
7) What is the exact manufacturer part number for this Eaton B-Line enclosure handle?
The manufacturer part number is WMHK-04, sold under the Eaton B-Line series as a lock latch and handle insert. It is a single configuration, so there are no finish or size options to specify when you order.
