Product Information
The SentryLock is a versatile, cost-effective pull-tight security seal designed to provide reliable tamper evidence across a wide range of industries and applications. Its practical design helps businesses protect goods, equipment and valuable assets while reducing the risk of loss, unauthorised access and interference during storage, handling and transportation.
Featuring a convenient pull-tight locking mechanism, the SentryLock allows the stem to be tightened around the item being secured, providing flexibility when sealing items of different sizes. Once inserted and tightened, the stem locks into position, helping prevent the seal from being loosened or removed without leaving visible evidence of tampering. This simple application process makes it suitable for routine security checks and high-volume sealing operations.
A key feature of the SentryLock is its acetal locking jaw, which enhances resistance to tampering and provides dependable locking performance. Similar to the AceLock seal, this locking mechanism is designed to help maintain the seal's integrity once applied.
Designed with affordability and versatility in mind, the SentryLock is suitable for businesses that require a dependable security seal across multiple operational areas. It can be used to secure bags, containers, boxes, equipment and other items where a visible indication of interference is important. Its straightforward design also supports efficient application by staff, helping minimise time spent on routine sealing tasks.
The SentryLock is available in a sustainable option incorporating at least 50% recycled materials and biodegradable additives, depending on the selected model. This provides an alternative for businesses seeking to incorporate more sustainable materials into their security and identification processes. Recycling is still recommended where appropriate, as the presence of biodegradable additives does not mean the seal should be disposed of in the environment.
Combining strength, tamper evidence and cost-effectiveness, the SentryLock is an ideal choice for businesses looking for a reliable general-purpose security seal for everyday use across logistics, warehousing, retail, transport and asset management.
