Description

STI STI-9115 Thermostat Protector Dome Tamper Screws and Bit

Overview

The STI-9115 is a polycarbonate dome protector designed to prevent unauthorized adjustment and tampering of thermostats in commercial and institutional settings. The unit ships complete with tamper-resistant screws and matching bit, securing the dome to the mounting frame and blocking access to temperature selector discs and controls without deliberate removal of the hardware.

Compatibility

The STI-9115 works with standard wall-mounted thermostats where dome-style protection fits the installation footprint. It is part of the STI thermostat protector family (which includes the STI-9110 and STI-9100S models) and accepts the supplied tamper screw set. Verify mounting frame dimensions before ordering to confirm fit.

Installation Notes

Installation is straightforward for both recessed and surface-mount applications. The frame includes air circulation holes to allow thermostats to sense ambient temperature without obstruction — a wall interior barrier prevents direct object insertion while maintaining sensor function. The dome mounts with the supplied tamper screws and bit; surface-mount installations may use optional spacers for standoff clearance. No special tools beyond the provided bit are required.

  • 1x Polycarbonate dome protector (STI-9115)
  • 1x Set of tamper-resistant screws
