The Spann-Box® Type 1 ensures precise tension monitoring thanks to SenseGuard technology and features a compact, robust design for reliable performance and long service life. The 24/7 monitoring function triggers a real-time warning signal as soon as the chain moves outside the optimal tension range.

The profile width is 20 mm, and you can choose between a short or long housing. Inside, there are three springs whose spring force can be individually adjusted to "light" or "heavy" to ensure the ideal tension pressure for your specific application. We are happy to provide consultation if you require special versions tailored to your individual needs.
