The patented Degree system from SARGENT
provides the right level of security for each
opening in your facility. Three levels of ANSI/
BHMA Grade 1 protection, from patented
keyway to UL437 certified, secures every opening.
A common key for all three levels of security
enhances key control and simplifies administrative
procedures. Key blanks are controlled through
authorized distribution and geographical
protection is available. Available for mortise, rim,
component and Large Format Interchangeable
Core (LFIC) cylinders, SARGENT offers the
right Degree of protection for every door in
your facility.
Benefits
• Patent protection from unauthorized key
duplication through 2027
• New keyway family protects system integrity
from legacy systems
• Keys are significantly stronger than
competitive systems
• User-friendly design with minimal components
provides easy field service
• Availability in all existing SARGENT cylinder
types provides cost-effective upgrade for
SARGENT facilities
• Bump resistance for added protection
Degree Level 1 (DG1) features a utility patented
keyway and provides protection against bumping
for mortise, rim and component fixed cylinders.
These cylinders easily retrofit into existing
hardware and are appropriate for most
applications. The keys for DG1 can only open
DG1 cylinders.
Degree Level 2 (DG2) builds on the utility
patented keyway of DG1 and adds patented side
bar locking with unique angled bottom pins that
provide end users with geographical exclusivity.
Cylinders provide protection against bumping
and picking. Because of its superior key control
and patent protection until 2027, DG2 products
are recommended for use in conjunction with
DG3 for new installations or when retrofitting
systems, including large format interchangeable
core systems.
Degree Level 3 (DG3) combines the utility
patented keyway and side bar locking with
unique angled bottom pins that provide end
users with geographical exclusivity, and adds
certification to UL437. They are classified as high
security because of their superior resistance to
physical attack and protection against unauthorized
key duplication. Because of its superior key control,
patent protection until 2027, and physical
strength, we recommend DG3 products for new
high-security installations or when retrofitting
systems, including large format interchangeable
core systems. SARGENT also offers anti-vandal
and high security locksets that complement
DG3 cylinders for those openings most vulnerable
to attack.

Construction Master Keying
(21- Option)
Degree™ Key System Technical Manual
Construction Master Keying (Lost/Wafer Design) for DG1-, DG2- & DG3-
SARGENT Degree cylinders when master keyed are offered with the
convenience of construction keying when specified with the 21- option.
This is not recommended with DG3 key systems or any system where strict
key control and management is enforced.
Construction keying simplifies the process when the building gets turned
over. With this feature, the 21- cylinder is master keyed with a special
construction feature in one of the chambers. The plug is prepped in two
places along both sides of the same chamber containing the construction
feature. This allows the construction master key to be used during the
construction phases.
It is highly recommended that all construction keys are collected and
accounted for once the project is complete to protect the integrity of the
key system. This is not recommended with DG3 key systems or any system
where strict key control & management is enforced.
Wafer
New systems supplied with six construction master keys unless
otherwise specified. Orders to existing key systems that require
additional construction keys are to be specified and ordered separately.
Orders with 21- will have all change keys shipped separately from
hardware. Six construction master keys provided per system unless
otherwise specified.
The 21- is not available with hotel function cylinders or large format
interchangeable cores (6300 series). If construction keying is required
for LFIC, specify 64-DG- construction keyed cores.
As change key rotates,
construction wafer falls into
“donut” hole in the side of plug.
Only construction wafer will
fall due to hole through its center.

Reproduction in whole or in part without the express written permission of Sargent Manufacturing Company is prohibited.
To allow for easier key and cylinder identification, SARGENT offers permanent stamping of keys and/or optional cylinder concealed stamping with
industry standard alpha-numeric key set symbols.
All DG keys are stamped with key set symbol and “DO NOT DUPLICATE” as standard.
All DG master and control keys are stamped with the key set symbol and the key system register # cylinders as standard, (Item B) unless alternate
stamping is requested on the order.
Master level keys do not include bitting numbers. Master level keys include system register numbers stamped on the first line and the standard visual key
control designations on the second line (Item B).
Change keys have one line for up to 7 characters for key set stamping available for permanent Visual Key Control
• Key and cylinder identified by industry standard alpha-numeric keyset symbols
• Cylinder-slide stamping available on mortise, rim, LFIC and all bored cylinders except for 8-Line and 7600 (Items C, D, & E)
• Core side engraving available for 8-Line and 7600 (Item F)

Tamper Proof Packaging
Reproduction in whole or in part without the express written permission of Sargent Manufacturing Company is prohibited.
