Plastic Fixed Length Trailer Security Seals

Our range of truck and trailer fixed-length security seals or 'ring seals' (due to the fixed loop they form when sealed) are ideal for a range of transport operations - including road, rail and many other applications spanning across industry. Ring seals are also referred to as truck seals and trailer door seals, as their main purpose is for use as an anti-tamper security seal on HGV trailer door locking hasps and curtain sider buckles... for more information view our guide to truck security seals. Truck seals are also suitable as an indicative security solution for petrol / bulk food / liquid tankers and shipping containers. Our ring seals are designed to be easily applied and removed without the need for tools, as they are designed to break by hand with a sharp tug. We stock-hold most of our seals in the UK for a fast lead time, and can also offer customisation as required.
