High-Security SFIC Padlock
This Best 21B772L606 padlock uses a seven-pin SFIC core that accepts any SFIC keyway for flexible key management. The stainless-steel shackle measures 5/16 in diameter with a 2 in height and 7/8 in width. A solid steel body with satin brass finish provides physical resistance for commercial doors, gates and equipment cages.
Weather-Resistant Construction
Stainless-steel shackle and steel body resist corrosion in outdoor or humid environments. No electronic components draw power or generate noise. Mechanical operation stays consistent across temperature swings. Zero bumpers simplify the lock body while maintaining alignment.
Replaces Standard Keyed-Alike Padlocks
Upgrade from basic keyed-alike models when master-key systems or restricted keyways are required. The SFIC core allows quick rekeying without removing the lock from the hasp. Not suited for buyers who need a non-removable core, a different shackle diameter or a lock that opens without a key.
Highlights
- Weather resistant design protects against outdoor elements
- Seven pin cylinder provides high security key control

Questions about this item
How do I fit the 5/16" stainless shackle through my hasp, and what step is often missed?
Align the 7/8" shackle width with the hasp opening, insert the shackle fully until both legs seat in the body, then turn the key to lock; the step often missed is verifying both shackle notches engage the locking bolts before removing the key.
What part of this padlock will need replacement first with daily outdoor use?
The 7-pin SFIC cylinder is the primary wear item; pins and springs can fatigue over time, so plan to re-key or swap the core rather than replace the entire lock body.
At what point does the 13/16" thick steel body show its limit during prolonged attack?
The 13/16" body thickness and satin brass finish resist cutting and corrosion, but sustained leverage attacks on the 2" shackle height will eventually deform the shackle before the body yields.
