The 'Keystone' format of modular connectors is generally associated with RJ45 data and RJ12 telephony connectors, but many other types of connector can be offered in the same 'snap-in' style. Some types are available with coloured housings, for circuit identification.
Details of the modules available are in the list below.
RJ45 types are available as 'back-to-back' female-female couplers, or as tool-less or Krone-style sockets. 'Tool-less' sockets have IDC termination with butterfly-style levers to close the housing and make the termination. They are unshielded unless otherwise indicated in the description.
Fibre types are available with generic, unshuttered connectors or Senko, shuttered types.
Clip-in blanks are available to fill unused holes in panels.
Two ranges of 19 inch unpopulated 'Keystone' style connection panels are available. See Canford Connection Panels - Keystone fit, which are available in grey and black finishes, and match other types in the Canford connection panels range. Also see TUK Keystone Connection Panels, which offer a cost-effective design, available in black.
