For specification purposes, 6-pin Peaks products have seven active pin stacks and 7-pin Peaks products have
eight active pin stacks. Texts of product specifications are available upon request.
Mechanical Testing
Testing of 8900/6800 series cores has proven them to be superior to the 8800/3800 series cores. The modern
alloys used in the shells and sleeves of the 8900/6800 series have remarkable bearing properties. In addition,
Kaba employs a patented two step process of plating and cladding on all 8900/6800 and 8400/3400 sleeves and
shells that makes the surfaces of these components harder than conventional brass surfaces. Plugs for both
8900/6800 and 8800/3800 series are made of brass because of its machinability.
Peaks cores and cylinders exceed 500,000 cycles with no measurable wear on shells and sleeves. Keys, key-
ways and bottom pins show normal wear. When 8900/6800 series cores are cut open, tool marks remain visible in
the pin chambers.
Pull tests have been successfully completed on Peaks cores in Arrow, Best, KSP, Corbin Russwin and Yale hous-
ings. The 8900/6800 cores actually require more force than 8800/3800 series cores. This is due to the behavioral
characteristics of the metals. All brass tends to shear, while the alloys employed in the 8900/6800 tend to distend
but hold.
Environmental testing
The standard ASTM B117 salt spray (corrosion) test for trim is 200 hours. After over 300 hours, both control and
operating keys work in Peaks cores, even before lubrication. After lubrication, the cores feel like new. Chrome fin-
ish cores do not discolor. Brass finish cores may darken with exposure to the elements.
