Kaba Peaks Preferred

Section 1 - 4
Introduction
Increment systems
A2 system: ten depths, numbered 0 to 9, shallow to deep, respectively. The increment of .0125" requires two
step progression. Choose a specific parity pattern by using either the odd or even bittings in any given posi-
tion. The preferred factory standard is A2 system.
A4 system: six depths, numbered 0 to 5, shallow to deep, respectively. The increment of .021" allows for one
step progression. Since there is no parity in A4, all key systems in any keyway are the same. Kaba strongly
suggests the use of A2 system whenever possible.
MACS : use 90 degree cutter
A2 System A4 System
140 MACS is 8–09, 90 are forbidden 140 MACS is 4–05, 50 are forbidden
150 MACS is 9–no forbidden combinations 150 MACS is 5–no forbidden combinations
Cut next to "peak"
A2 system: #7, 8 or 9 cuts next to the “peak”
require #1011 or equivalent cutter.
When master keying, progress this position last.
A4 system: #4 or 5 cuts next to the “peak”
require #1011 or equivalent cutter.
When master keying, progress this position last.

Pinning
The same pins are used for all cylinders and cores, except Corbin Russwin and Sargent large format inter-
changeable cores and the Universal 8400-xx-1095/1099 and 3400-xx-1095/1099 key-in-knobs, which require
the J or K series bottom pins. Non-original pins will not work properly in Kaba products and their use
voids product warranty.
All products are top loaded. Capped small format interchangeable cores require the correct capping block
(140 or 150). Spring covers are installed with a staking tool and fixture. Combinated conventional cylinders
may be rekeyed by removing the spring cover or by using a Peaks follower tool and setup key.
Lubrication
Poxylube, a dry spray, is the factory recommended lubricant.
Key Blanks
1. Only keys bearing your unique, factory stamped, Key Blank ID number may be duplicated.
2. Key blanks may not be sold, lent, or given away.
3. Return of key blanks, for any reason, must be made directly to Kaba or to any of the parties as outlined in
your contract.
Core marking
Do not stamp the face of the core as the patent pin chamber may collapse. Kaba strongly discourages Visual
Key Control (VKC) for security reasons. Concealed Key Control (CKC), such as marking the side of the core
with a fine point magic marker, is recommended, and is the factory standard. See section 3–1 for complete
marking instructions.
