B-LINE 25278 A – Frequently Asked Questions
1) What does the Eaton B-Line 25278 A latch key actually fit?
It is the triangle flush latch key for Eaton B-Line security latch kits used on Type 4 and Type 12/13 enclosures. If the flush latch on your enclosure door has a recessed triangular socket, this is the operator that turns it. It is a key only, not a complete latch assembly.
2) Will a triangle key work if my enclosure latch takes a square or hex insert?
No. The 25278 A is cut for a triangular socket only. A square, hex, or slotted flush latch needs the matching key for that shape, so check the socket in your latch before ordering.
3) Is the B-Line triangle latch key steel or plastic?
Steel. That matters for wash-down and industrial panel work, where a plastic key gets chewed up on a latch that is turned daily.
4) Is this B-Line enclosure latch key UL Listed?
Yes, the 25278 A carries a UL Listed marking, which helps when you are documenting accessories on a UL enclosure for an inspector or a plant standard.
5) Can I standardize one key across all my Type 12 control panels?
If the panels use B-Line triangle flush latches, one 25278 A key operates them all, so maintenance techs can carry a single key instead of a shape for every door. Order by model 25278 A when you need spares.
6) Does the 25278 A include the latch itself?
No. This is the key that operates a B-Line Type 4 / Type 12 security latch kit, not the latch, gasket, or door hardware. If the latch body is damaged you need the latch kit as well.
7) How big is the engaging end on the 25278 A latch key?
The working dimensions are given as .31 in height, .31 in length/depth and .25 in width, with a weight of .001 lb. Compare those against the socket in your flush latch if you are matching an older door.
