Amron Inner-Lock Combo Box with Sound Powered Phone

The Amron International Model 3125 Inner-Lock Combo Box is a small, compact package that saves precious space in the Inner Lock. As part of Amron's "Easy as 1-2-3 System," Model 3125 allows you to set up your chamber communications, auxiliary and electrical wiring with ease, just as the name implies. This system is a complete "off the shelf," pre-tested chamber communication and wiring system for a double lock chamber. The system is designed for installation by non-electrical type personnel and requires only a crescent wrench and a screw driver. This eliminates the engineering and hunting for all the bits and pieces necessary to properly wire a chamber.

  • Talk-back Speaker and on/off switch
  • Sound powered phone and bracket
