The N1JLK is a key lock for N1J and N1W enclosures from the Type 1 Lock Kit range. The series ordering table lists it as fitting the N1J, N1W, CHKO, N1WF and SWB enclosure series, making it a practical way for contractors and facilities staff to secure indoor Type 1 enclosures against casual access.

The lock installs in place of the existing slotted latch, or in the cutout hole provided. Its cam position is reversible for other applications, and the lock kit maintains the enclosure's NEMA1 rating once installed.

The part drawing for the N1JLK shows 1.57 and 0.98 dimensions and an 85° angle across its top, front and side views. The lock ships in a bag with a shipping weight of 0.06 lbs (0.03 kg).

The N1JLK is REACH compliant and RoHS compliant and is identified by UPC 623980420011 and UNSPSC 39121321. Its short description is LOCK KIT FOR N1J. For 1420 and N1A series enclosures, the matching part in the same range is the 1427LKN1 NEMA 1 flush lock kit. Because this lock is listed for five enclosure series, one part number can cover a mixed installed base of N1J, N1W, CHKO, N1WF and SWB enclosures.
