Surface Mount Base STI-9621

The Safety Technology International STI-9621 is a surface-mount base designed to shield motion detectors from vandalism and accidental damage. It serves installers and property owners who need durable protection for indoor or outdoor security devices. The open-back steel guard fits directly over compatible detectors to maintain sensor coverage while adding a physical barrier.

Included Mounting Hardware

Supplied mounting hardware allows the guard to be fixed to walls or ceilings without sourcing separate fasteners. The white coated steel construction resists corrosion and blends with light-coloured surfaces. This accessory changes the installation by adding a robust cage that does not obstruct the detector’s field of view.

9-Gauge Steel Cage Capacity

The 9-gauge coated steel wire withstands operating temperatures from -40 to 250 degrees Fahrenheit, making it suitable for harsh indoor and outdoor environments. The cage dimensions of 5 3/4 inches wide, 4 1/2 inches deep and 7 inches high accommodate standard motion detectors. It is not intended for oversized sensors or devices requiring a fully enclosed housing.

Questions about this item

Will the coated steel guard need repainting after outdoor exposure?

The white coating on the 9-gauge steel resists corrosion across the full -40 to 250 °F operating range, so repainting is not required under normal conditions.

What is the maximum ambient temperature the STI-9621 can withstand before the steel or coating degrades?

The guard is rated for continuous operation up to 250 °F, which is the upper limit of its cUL-listed temperature range.

Does the open-back steel cage trap heat around the motion detector during all-day operation?

The open-back design allows free airflow, so the detector runs at ambient temperature without added heat buildup inside the guard.
