B-LINE T4LDLB – Frequently Asked Questions

1) Will the Eaton B-Line T4LDLB latch keep a NEMA 4 enclosure watertight?
Yes. The T4LDLB quarter-turn latch is rated NEMA 4, so it is built to hold the gasket seal on a hose-down or wash-down enclosure rather than just a dry indoor box. It is also UL Listed. If your enclosure is only a NEMA 1 indoor box, this is more latch than the opening needs, but it will still work.
2) What kind of latch is the B-Line T4LDLB and how does it open?
It is a Type 4 large slotted latch, part of Eaton's B-Line locks, latches, inserts and handles line for enclosure doors. You turn it a quarter turn with a slotted driver or coin-style tool, not with a key or a handle. If you need keyed security on the door, this is the wrong insert for you.
3) Does the T4LDLB fit a JIC or ground-mount enclosure door?
Both. Eaton lists the T4LDLB under Type 4 quarter-turn locks and latches for JIC and ground mount, with ground as the stated mounting method. That covers the free-standing and pad-mounted enclosures electricians see outdoors as well as JIC-style industrial boxes.
4) What part number do I order for this Eaton B-Line quarter-turn latch?
Order it as Eaton B-Line T4LDLB. That is the manufacturer part number and the only configuration in the series for this black Type 4 large slotted latch.
5) What color is the Eaton B-Line T4LDLB latch?
Black. If you are standardizing hardware across a run of enclosures and the rest of your doors carry black inserts, this matches; there is one model on offer, T4LDLB, so there is no alternate finish to specify.
6) Which enclosure size is the T4LDLB latch referenced to?
Eaton references it to a 36 in x 30 in panel. That is the enclosure it is catalogued against, so it suits full-size door panels rather than small junction boxes.
