This versatile, pull tight seal provides double the security when sealing up your applications. Do not underestimate it, as, despite its small dimensions, it is very strong with a tensile strength of 18kgf.

This Fort Double Twin Lock Seal is made from Polypropylene plastic. This durable securing strap gives the seal enough strength to match different user applications.

With an easy to remove tear off feature, the breaking point of this seal is located at the ribs.

Laser Marking

This Fort Lock Seal is etched with permanent laser marking which offers the highest level of security for each application. A variation of markings can be engraved across this seal including barcodes, serial numbers, your company name or logo for identification purposes.

Up to 10 digits can be marked upon this seal, which is great, again, for security purposes as it cannot be removed or replaced without showing clear signs of tampering.
