Buying Guide: Key Considerations For High Security Puck Locks
- Shackle design: Hidden shackles offer greater resistance to bolt cutters and prying. Look for fully shielded shackles to minimize attack surfaces.
- Material and corrosion resistance: Aluminum bodies are common for their light weight and corrosion resistance. Stainless steel shackle or hardened cores add cut resistance.
- Lock core security: Anti-pick features (e.g., 12-pin cores) improve resistance to picking. Keyed-alike options simplify key management when you have multiple locks.
- Compatibility with hasps: Measure your hasp diameter and width to ensure a proper fit. Some models include oversized openings to accommodate common trailer hardware.
- Weather and environment: IP ratings and treated finishes help prevent rust from rain, salt, and dust. Consider units rated for outdoor or marine use if exposed to the elements.
- Keys and maintenance: Note the number of keys included and whether the lock uses a common keyway or a unique key system. Plan for spare keys to avoid lockouts.
- Installation and weight: Heavier locks can deter theft but may require stronger hasps and mounting points. Ensure marine or vehicle mounting surfaces can handle the load.

- Should I get a keyed-alike set or individual locks? — Keyed-alike sets simplify key management when you need multiple locks operated by the same key, reducing clutter and loss risk.
- How do I verify fit for my trailer or gate? — Measure the hasp opening, including diameter, width, and clearance around the shackle. Compare with the lock’s dimensions and shackle design.
- Is an IP68 rating important for puck locks? — IP68 indicates dust-tight and submersible protection, beneficial in harsh weather or dusty job sites where water exposure is common.
- Do security locks affect warranty or service terms? — Warranty terms vary by brand and seller; check the product listing for details on replacements or refunds related to fit issues.
