Padlock for Keepsake Boxes
The Master Lock 1LN is a laminated steel padlock designed to secure memory books and keepsake containers. Its 5-3/4 inch vertical shackle clearance fits around thick spines or bulky hasps where standard shackles cannot reach. The 44 mm wide body houses a 4-pin cylinder and dual locking levers. Two keys are supplied with each lock.
Hardened Shackle Resists Cutting
A 3/4 inch internal width hardened steel shackle provides extra resistance to cutting attempts. The laminated steel body construction adds structural strength against physical attack. Proprietary rustproofing protects the mechanism and shackle from corrosion over extended storage periods. The 4-pin cylinder mechanism helps prevent picking.
Not for High-Security Doors
This padlock is not suited for securing exterior doors, gates or high-value assets requiring heavy-duty shackle diameters or advanced cylinder protection. Buyers needing shrouded shackles, electronic access or master-keyed systems should look elsewhere. The long shackle design prioritises clearance over maximum physical security. It serves keepsake storage, not perimeter defence.

Questions about this item
How do I install the Master Lock 1LN padlock on a hasp or chain, and what step is often missed?
Thread the 5-3/4" shackle through the hasp or chain, snap it into the 44 mm wide laminated steel body until both dual locking levers click, then turn the key to verify both levers engaged — skipping the double-click check is the common error.
What maintenance or replacement will the Master Lock 1LN padlock need over time?
Apply a light PTFE or graphite lubricant into the 4-pin cylinder and shackle holes annually; if the proprietary rustproofing wears and the hardened steel shackle shows corrosion or the key binds, replace the entire padlock.
What limit appears first when the Master Lock 1LN padlock sees sustained outdoor use?
The proprietary rustproofing on the laminated steel body and hardened steel shackle degrades first under constant moisture and salt exposure, leading to surface corrosion that can seize the 4-pin cylinder and dual locking levers.
