Padlock with 5/16 inch Shackle
The Best 21B782L606 is a keyed padlock built around a 5/16 inch stainless-steel shackle and a seven-pin cylinder. It suits anyone securing gates, toolboxes or storage units where a weather-resistant brass-finished body is preferred. The gold satin finish resists corrosion in outdoor or humid environments.
Upgrade from Lower-Pin or Non-Weatherproof Locks
Moving from a five-pin or non-stainless shackle lock adds pick resistance and eliminates rust-related seizure. The jump is worth it when the protected asset justifies a higher security rating and the lock must survive rain or salt air without binding.
Simple Keyed Installation
Insert the correct key, turn and remove the shackle; no tools or wiring are required. The only common issue is lost keys, because the cylinder accepts any SFIC keyway and keys are not duplicated by the supplier. Control-key registration is not required, so a locksmith can rekey on site if needed.

Questions about this item
Will the 5/16 in shackle diameter and 7/8 in shackle width fit my hasp?
The shackle measures 5/16 in diameter, 4 in height and 7/8 in width. Compare those three dimensions to your hasp opening and clearance before buying.
How do I install the cylinder into the gold satin-brass body, and what step is often missed?
Insert an SFIC core that matches the 7-pin configuration, then tighten the control lug. The step many miss is verifying the control key works before closing the shackle.
When should I replace the stainless-steel shackle or the 7-pin cylinder?
Replace the shackle if it shows bending, corrosion pitting or wear at the 5/16 in cross-section. Replace the cylinder if keys bind, rotate roughly or fail to retract the locking bolt.
