Aſter lubrication, the cores worked like new. Keying Specs If you are familiar with SFIC A2 or A4 systems, Peaks will be a breeze. SFIC is done almost exactly the same way, al- though the pin stacks are larger in fixed cylinders due to plug variations and shell dimensions. Beware of the BPs! The SFIC bottom pins for Kaba Peaks are .003” shorter than with traditional SFIC pins. Manufacturers advise that you use the OEM pin kit, especially for bottom pins. Because the increment is so close to the tolerance variation, cores may not operate or be extremely difficult to operate. Combinating Peaks Preferred — Easy as Cake!

This information is im- portant to the institutional locksmith, especially when considering products that provide key control for specified periods. Additionally, since SFIC is so prevalent, little adjustment is needed to use this product line and take advantage of its immense offerings for retrofitting existing hardware within a facility.
