The BSC PREFERRED IAA00019482 is a nickel-plated key blank designed for use with National-style mailbox locks. Constructed from brass with a nickel-plated finish, this blank provides a durable base for key cutting and duplication. Each bag contains 10 key blanks, making it a practical choice for locksmiths, property managers, and building maintenance professionals who need to produce multiple copies at once. The brass core resists corrosion and holds cut profiles cleanly, while the nickel plating adds surface protection and a consistent finish across all blanks in the set.
This key blank is suited for residential and light commercial applications where National-style mailbox hardware is installed. Apartment complexes, multi-unit residential buildings, and commercial mail centers commonly use this key profile. Locksmiths and facility maintenance technicians will find the 10-blank per bag quantity useful for high-volume key cutting jobs or stocking a service vehicle with ready-to-cut inventory.
Designed as a replacement-style key blank for National-pattern mailbox locks commonly found in residential and light commercial mail installations.
Key cutting should be performed by a qualified locksmith using a compatible key cutting machine sized for the National mailbox blank profile. Verify the lock keyway matches the blank profile before cutting. No special tools or codes are required beyond standard key duplication equipment and practices.
