Buying Guide
Key considerations when choosing a stainless steel disc padlock:
- Security Level: Look for hardened steel components and boron-carbide shrouks for higher resistance to cutting and picking.
- Environment and Durability: Stainless steel and chrome plating resist rust and corrosion, crucial for outdoor or damp locations.
- Size and Fit: Measure backset, cross bore, and door thickness to ensure the lock fits the hasp or shackle opening.
- Keying System: Decide between keyed-alike, keyed-different, or multiple-key options based on access control needs.
- Shackle Design: Shrouded or armored shackle minimizes exposure to bolt cutters and tampering.
- Quantity and Management: Bulk packs save per-unit cost but require better key management and inventory control.
