Sargent 130051SIZE2 Size 2 Master Pin

Product Description

The SARGENT 130051SIZE2 is a Size 2 master pin used in pin tumbler lock cylinders as part of a master keying system. Master pins are small cylindrical components inserted into the pin stack between the key pin and driver pin, allowing a single cylinder to operate on both a change key and a master key. This component is installed by locksmiths and security hardware professionals during cylinder preparation, rekeying, or master key system builds. The part ships as a single unit and is consistent with SARGENT's architectural hardware line, which serves commercial, healthcare, industrial, and educational facilities.

Master pins are used wherever a pin tumbler cylinder must be keyed into a master key system. This part is appropriate for commercial and institutional applications where multiple access levels are required across a building or campus. The Size 2 designation refers to the pin's specific height increment within SARGENT's pin sizing progression, determining the shear line differential it creates between the change key cut and the master key cut. Security hardware professionals and licensed locksmiths install this component during initial cylinder setup or when reconfiguring an existing master key system.

Installation Notes

Master pin installation should be performed by a licensed locksmith or qualified security hardware technician. The cylinder should be fully removed from the door hardware and the plug extracted before accessing the pin chambers. Use appropriate pin tweezers and a plug follower to avoid losing spring tension components. Follow the master key system schematic precisely, as incorrect pin sizing will result in a non-functional shear line.
