Electronic sounders can be vandalised, stolen or smashed in a sports hall but the STI9615 and STI9617 Stoppers will prevent this. The white plastic-coated 9 gauge steel cage can be fitted inside or outside and will securely protect sounders of all sizes (check the interior dimensions further down the page to find the right size).

STI Stoppers should be fitted in any areas where the risk of abuse or damage is severe such as care homes, sports halls and warehouse loading bays. A huge range of steel Stoppers to fit detectors, emergency lights, clocks, motions sensors, CCTV and fluorescent lights is available on request by calling 0800 321 3145.

Suitable for schools, universities, care homes, sports halls and anywhere with a history of damage or abuse
