Building further on Crewsaver's leading reputation for cutting-edge technology - EXOLOK provides increased security for gas cylinders attached to lifejacket operating mechanisms. Simple yet innovative. EXOLOK holds a lifejacket cylinder securely in position and provides a clear indication if the cylinder moves, becomes unscrewed or is tampered with. Constructed from durable and lightweight materials, this simple yet highly effective design is unobtrusive while adding another protection level to the all-important firing system. Compatible with existing products and can be retrofitted to lifejackets with most UML and some Halkey Roberts (orange) or Halkey Roberts 840 (yellow) operating mechanisms.

Even for those operating in the most demanding environments, with an EXOLOK you can rest assured - your lifejacket protection is always locked in.
