Welcome to the Homepage of SIOTRA.

Our main product range can be found at www.studcollar.co.uk although we do supply additional items on EBAY. Simply type SIOTRA in the EBAY search box to find a selection of the quality products available from us.

We manufacture a range of products in the UK. These we believe to be the best in the world. Indeed, it has taken many years of research to finally supply the current versions of SUPERMAX and FLEX.

Should you wish to contact us, please forward an e-mail to info@siotra.co.uk
