Specification Sheet

Falcon offers two different construction key systems

depending on the size of and application within the project.

Both systems permit the installation and use of regular

door locks during construction, yet completely preserve the

security of the keying system for the building owner.

The Master, Grand Master and change keys are never with

the locks during the construction phase of a building. Only

the “construction” keys are sent to the jobsite. Where

the job permits we will use the “Lost Pin” system as our

standard system for construction keying. Larger or more

complicated jobs may require use of the “Blockokey®

System” for construction keying.

ÒDISPOSABLE CONSTRUCTIONÓ

INTERCHANGEABLE CORES

The disposable construction core (1408) is an inexpensive

alternative to interior keyed construction cores. This core

should be used on interior door applications or where

security on a site is not a concern. No keys need to be

issued. The disposable core is inserted in the lever or knob,

and is operated by a thumbturn, which retracts the latch

bolt. Use either brass or permanent construction cores on

exterior doors or secured areas when security is needed.

LOCKS WITH THE

ÒLOST PINÓ SYSTEM

Our “lost pin” construction system consists of one

construction pin and a shallow hole in the side of the plug.

All lock cylinders on a speciﬁ c project are operable by a

special “project key.” The building contractor may assign

all duplicates of this key to workers and subcontractors

as required. No regular change keys or master keys are

needed on the job, eliminating the possibility of subsequent

exposure from lost or stolen keys.

Construction Key Ð KB566

With the construction key in use the construction pin is

always in the cylinder plug, sitting on top of the bottom pin.

Master Key Ð KB578

With the master key inserted the construction pin is pushed

up into the cylinder housing. Rotating the master key to the

right drops the construction pin into the hole in the plug,

eliminating any future use of the construction key.
