Secure SFIC Padlock
The Best 21B722L606 is a 7-pin keyed padlock built around a small-format interchangeable core that accepts any SFIC keyway. Its stainless-steel shackle measures 5/16 in diameter with a 1 1/2 in clearance and 7/8 in width, while the steel body offers a satin brass finish and weather resistance. This lock suits facilities that manage access through a restricted key system and need a compact, pick-resistant barrier for interior or sheltered exterior points.
Installation Fit
The 13/16 in thick body and 2 1/16 in height allow the lock to sit in standard hasp, chain or locker openings without protruding excessively. A 7/8 in shackle width clears typical staple eyes and chain links, and the 1 1/2 in shackle height provides enough reach for double-hasp arrangements. No control key registration is required, so the core can be swapped or re-keyed by existing SFIC tools, freeing the installer from proprietary key blanks and reducing key-carry bulk for maintenance staff.
Upgrade Path
The 7-pin SFIC core replaces lower-pin or fixed-keyway padlocks where key control must scale across dozens of doors without issuing unique mechanical keys for each. The jump is worth it when a facility moves to a master-key hierarchy that demands quick core changes and audit trails tied to the SFIC system. It is not suited for buyers who need a non-removable core, a shrouded shackle for bolt-cutter resistance, or a larger shackle diameter for heavy chain links.

Questions about this item

The 7-pin cylinder provides a high number of possible key combinations, making sustained picking or bumping significantly more difficult than lower-pin alternatives.
Does the stainless steel shackle and steel body handle outdoor heat and moisture without seizing?
Yes, the stainless steel shackle and satin brass finish on the steel body are weather resistant, preventing rust and seizing during long-term outdoor exposure.
Which existing key system must I already use for this padlock to integrate without new keys?
This padlock accepts any SFIC keyway, so it works with your current Stanley or Best SFIC key system without requiring new keys.
