Installation of double-cylinder locks for maximum security

Double-cylinder locks require keys on both sides, preventing anyone from opening the door from the inside through windows, cracks, or nearby openings. They are perfect for glass doors, interior grilles, or exposed entrances. Their design ensures complete access control and prevents tampering from either the inside or outside.

They provide superior security in residences where minimizing the risk of intrusion is desired.

Types of double cylinder locks:

A) European double cylinder (trunk lock, profile)

B) American double cylinder (dead bolt, mortise lock)

C) Double reinforced anti-bumping cylinder (dead bolt)
