B-LINE 7MT1SLK – Frequently Asked Questions

1) Can I swap a quarter-turn latch on my enclosure door for this B-Line insert?
Yes. The 7MT1SLK is built so latch inserts interchange with quarter-turn latches, so it drops into the same insert position rather than needing a new door cutout.
2) Is this insert suitable for an outdoor or washdown electrical enclosure?
No. The 7MT1SLK is rated NEMA 1, which is indoor, general-purpose protection against incidental dust and contact only. For wet, outdoor, or hosedown locations you need an insert designed for a NEMA 3R, 4, or 4X enclosure instead.
3) Is the B-Line 7MT1SLK insert UL Listed for use in a panel enclosure?
UL Listed, yes. That matters on institutional and inspected work where every component in the enclosure door has to carry a listing.
4) What exactly am I getting with part number 7MT1SLK, the whole latch or just the insert?
You're getting the insert itself, the 7mm square security insert that goes into the latch, not a complete handle or latch assembly. It falls in Eaton B-Line's lock, latch and handle line for Type 1 panel enclosures. If your door has no latch body yet, order the latch as well.
5) We want to stop tenants opening indoor control panels by hand. Does this solve it?
That's what the insert is for. Replacing a plain quarter-turn with the 7mm square insert means the door only opens with a matching 7mm square key, keeping unqualified hands out of indoor NEMA 1 panels. Use the same insert across a building and one key serves every panel.
