Product Information
The SentryLock is a versatile pull-tight tamper-evident security seal designed to deliver reliable performance across a wide range of industries. Its adjustable design allows for a tight, secure fit on different applications, while its robust construction provides higher breaking strength than comparable seals without compromising on cost-effectiveness. This makes it an ideal choice for organisations seeking dependable security on a budget.
At the core of the SentryLock is a durable acetal locking jaw, similar to that used in the AceLock range, which offers enhanced resistance to tampering, including heat-based interference. Once applied, the seal cannot be loosened or removed without visible damage, ensuring clear evidence of any unauthorised access. The smooth strap and user-friendly locking mechanism allow for quick, tool-free application, making it suitable for high-volume or fast-paced environments.
As part of B-Sealed’s commitment to sustainability, the SentryLock is available in an eco-conscious range, including options manufactured with at least 50 percent recycled materials and versions incorporating biodegradable additives. These alternatives offer the same reliable performance while helping reduce environmental impact. Recycling remains the preferred disposal method wherever possible.
