B-LINE T4PLWNB – Frequently Asked Questions

1) Will the Eaton B-Line T4PLWNB wing knob keep my enclosure NEMA 4 rated?
Yes. The T4PLWNB is a Type 4 quarter-turn lock rated NEMA 4, so it is built to keep a washdown/hosedown enclosure sealed when the door is latched. It is also UL Listed. Use it on Type 4 enclosures; putting a non-Type 4 latch on a Type 4 box is the usual way an enclosure loses its rating.
2) Can you padlock the B-Line T4PLWNB wing knob latch?
That is the point of it. The T4PLWNB is the large pad lockable wing knob version, so the knob has a provision to accept a padlock shackle and can be locked out without a key or tool. Hand turn to open, padlock through it when you need the door secured against casual access.
3) Is this quarter-turn latch meant for a JIC or ground mount enclosure?
Both. The T4PLWNB falls in Eaton B-Line's Type 4 quarter-turn locks and latches for JIC and ground mount enclosures, and its mounting method is ground mount. If you are fitting a wall mount Type 4 box, check that the door prep matches the quarter-turn insert you already have.
4) Which enclosure panel size is the T4PLWNB associated with?
Eaton lists the T4PLWNB against a 42 inch by 30 inch panel. That is the enclosure size this Type 4 pad lockable wing knob is called out for, so it is the safe match if that is the box on your job.
5) Is the pad lockable wing knob the right choice, or should I use a keyed enclosure lock instead?
A wing knob quarter-turn like the T4PLWNB opens by hand, no key or tool, and takes a padlock when you want it secured. That suits maintenance access where technicians open the panel often and security is handled by the site's own padlock keying. If you need keyed access control or a single key across a facility, a keyed quarter-turn insert is the better call, since a padlock hasp means someone has to carry and manage the lock separately.
6) What is the exact part number to order this Eaton B-Line wing knob under?
Order it as B-Line T4PLWNB. That is the manufacturer part number for the Eaton B-Line Type 4 large pad lockable wing knob in black, and it is the only configuration offered under that number.
7) What size is the B-Line T4PLWNB latch and how much does it weigh?
The wing knob measures .75 x .75 x .625 inches and weighs .453 lb. Small enough that it adds nothing meaningful to door weight, but confirm your door cutout matches a quarter-turn prep before ordering.
8) What color is the Eaton B-Line T4PLWNB wing knob, and will it match my other enclosure hardware?
Black finish. If you are standardizing hardware across a run of Type 4 enclosures, the black wing knob is what B-Line supplies on this pad lockable version, so the fleet will match if you spec the same part on every door.
