A permanently
mounted lock with indicative
electronic sealing.

CryptaLock is a heavy duty slam
lock designed for roll-up shutter
doors and barn doors of trucks. Every time the locking bar
is closed, the doors and the load are made secure and a
random 4 digit electronic seal number is generated.
The seal number is retained and visible
by the mere touch of a button until CryptaLock is
opened. The last 50 seals and openings are recorded in the
electronic memory together with times and dates. The memory
is downloadable to a handheld PC.
