COMSEC Ancillaries

Driven by industry requests for more reliable components, less expensive solutions, and niche requirements, our COMSEC Ancillaries ensure your security devices have reliable power and can mount into standard IT racks.

Includes hardware (bolts & washers) required to retain COMSEC devices
Supports mounting most SUB-U appliances


Our unique COMSEC device shelving solutions enable you to rigidly mount various Type 1 COMSEC devices within a standard 1U or 2U IT rack space. They support the retention of several vendors’ COMSEC products, allowing large organizations to inventory a single shelf for several products or applications.

The COMSEC Uni-Shelf supports the following devices:

  • (2) General Dynamics KG-175D
  • (2) General Dynamics KG-175F
  • (2) General Dynamics KG-175G
  • (2) Viasat KG-250 (2 total)
  • (3) Viasat KG-250X (3 total)
  • (3) Viasat KG-250XS (3 total)
  • Most SUB-U appliances


The 2U tall variant of the COMSEC Uni-Shelf works the same as the 1U version. It is available for applications requiring additional clearance and rigidity. It also prevents a user from mounting another item directly above the COMSEC devices. The 2U shelf is compatible with the IAS quick release tray kit for General Dynamics’ KG-175D.

We also offer the option of full extension slide rails for the COMSEC Uni-Shelf that allows you to access the back of your gear from the front of the rack.
