Construction/Contractors

                            Construction master cylinder

Mul-T-Lock has developed a new-concept High Security
construction master cylinder, that provides construction
contractors with maximum convenience, while ensuring peace
of mind for new property owners.

Contractors using the new product enjoy control of all
apartments on the construction site - or even on several sites -
with one master key.

Each cylinder in the system also has an owner key, provided
to the owner when he/she moves into the apartment.

At this time a technician turns a special change key in the
cylinder, disabling the contractor’s master key. This procedure
is not reversible.

This creative new solution is fully contained in the cylinder
itself and requires no supplementary devices.
