## Summary description

Keystone mount adapter designed for use with ST simplex fiber adapters. Produced by Alantec (model MKA-ST-C) in black finish, it provides a compatible mounting interface for inserting an ST simplex adapter into a keystone-style wall plate or patch panel. Suited for fiber optic installations where ST simplex connectors must be mounted in standard keystone openings.

## Long description

The Alantec Keystone mount adapter for ST simplex adapter (black) provides a keystone-compatible mounting interface for ST simplex fiber optic adapters. It is designed to hold a standard ST simplex adapter securely within a keystone-style faceplate or patch panel opening, enabling installation of ST connectors where only keystone ports are available. The compact, low-profile form factor keeps the adapter flush with panels and wall plates, maintaining a neat installation appearance while providing reliable mechanical support for fiber connections.
Advantages
This keystone mount adapter ensures compatibility between ST simplex connectors and keystone-format panels without requiring modification to existing faceplates. The robust construction resists wear from repeated insertions and removals of ST plugs, and the black finish provides a discreet, professional look in mixed cabling environments. The adapter’s precise dimensions provide a secure fit in standard keystone openings, reducing play and maintaining optical connection alignment.

How to use
Insert the ST simplex adapter into the keystone mount adapter so that the adapter snaps into place.

Usage recommendations
Handle fiber connectors and adapters with care to avoid contaminating end faces; clean fiber end faces with appropriate tools before making connections.
