Our range of plastic fixed-length security seals or ring seals are ideal for a range of transport operations - including road, rail and many other applications spanning across industry. These types of seals are called ring seals due to the fixed loop they form when secured. They are also called truck seals or trailer seals, as their main purpose is as a security seal on HGV trailer locking hasps or curtain sides buckles - they are also suitable as an indicative 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 - our trailer seals are designed to break by hand with a sharp tug. We stockhold most products for a fast lead time, and can also offer customisation as required.
