From the Paloma brand these cylinder locks
are anti-drill, pick and corrosion-resistant. Coming in various lengths to
suit door thicknesses and applications with or without keys, they are made of
brass.
Consisting
of a lever handle, cylinder lock
and lock casing, this
combined make-up comprises the essential components of door hardware.
This enables
the operation of a door by providing a means to grasp and turn the handle,
engage the locking mechanism via the cylinder and secure the entire assembly
within the door frame.
