Two ways to lock in.
CATLOK PRO
Built for professional connections.
CATLOK PRO is the interlocking coupler for the environments where a dropped connection costs real money: server racks, structured cabling, camera runs, conference rooms, and every line pulled through a raceway or ceiling tray. The reinforced housing and internal stop-and-ramp geometry are designed for repeated cycles, dense installs, and the abuse of a working pull.
CATLOK CORE

Gaming rigs, home offices, streaming setups, security cameras, and every cable that counts. CATLOK CORE brings the same patented interlock to the connections behind your desk and around your house, so the plug that always works loose finally stays put. Low-profile, tool-free, and locked in seconds.
Wherever the cable goes, the lock goes too.

More than a connection.

An installer problem. A better solution.
CATLOK was developed in response to a common challenge in the field: Ethernet connections that can be accidentally disconnected. The solution was a new approach to the traditional inline Ethernet coupler—one designed not only to connect cables, but to help secure the connection.
