Product Information

The SentryLock is a pull-tight tamper-evident security seal that offers multipurpose use in various industries to minimise losses. Its design ensures a higher breaking strength compared to similar seals while remaining cost-effective. The acetal locking jaw, similar to the AceLock seal, enhances security against tampering.

B-Sealed now offers sustainable range of products, including security seals made from at least 50% recycled materials, and biodegradable additives.

B-Sealed always recommend our customers dispose all our plastic seals properly after use in recycle bins, first and foremost.
