Thermostat Protector for Public Areas

This clear polycarbonate cover shields small thermostats and energy sensors from vandalism, accidental damage and unauthorised tampering. The lockable design is intended for flush-mount installations where abuse is a recurring problem. Air-circulation holes in the frame let the protected device operate normally. An inner wall blocks access to dials and levers.

Spacer Options for Surface Mounting

Two spacer accessories, SUB-901 and SUB-905, convert the same cover for surface-mount use when a flush opening is not available. The choice of spacer changes the stand-off depth to suit different wall conditions. No additional software or mounting hardware is referenced in the specifications. The cover itself remains unchanged regardless of the spacer selected.

Model STI-9105 Identifies the Flush Version

The part number 9105 designates the flush-mount variant of this protector. Buyers needing the surface-mount configuration must order the appropriate spacer separately. The smoke-coloured alternative carries a different suffix and is not the item described here. Specify 9105 when the installation calls for a recessed fit.

Questions about this item

Will the polycarbonate cover need any replacement parts over time?

The cover is a single moulded polycarbonate shell with a built-in key lock; no consumable cartridges, filters or batteries are part of the design.

What stops the thermostat inside from overheating when the cover is locked all day?

Ventilation holes in the frame let air circulate freely around the thermostat so normal operation continues without heat build-up.

Does the clear polycarbonate yellow or warp after months of indoor use?

The 1/8" heavy-duty polycarbonate is formulated for indoor durability and resists yellowing and warping under normal room temperatures.
