Europa Defendo Aldrop: Extra Security for Gates and Main Doors

An aldrop is a traditional drop-bolt style lock that adds a second line of security to a door or gate. The Europa Defendo Aldrop is shown in the video above, whose title mentions a 15-year warranty.

Where an aldrop helps

• Outer gates and grille doors
• Terrace doors and rear entrances
• Shop shutters and store rooms
• As a second lock on a main door

About the warranty

The video's title mentions a 15-year warranty. Warranty terms are set by the manufacturer and can include conditions, so please ask us for the exact current terms in writing before you buy.

What to check

1. 1Door or gate material and thickness
2. 2Position for the lock so the bolt aligns exactly with the receiver
3. 3Finish suited to outdoor use if the lock faces rain
4. 4Number of keys and key quality

Fitting tips

Mark the position carefully, drill neatly and fix with the correct screws. If the bolt does not drop easily, correct the alignment rather than forcing it. A little lubricant once a season keeps it moving, especially after the monsoon.

Use it with other locks

An aldrop works best next to a good main lock. See the Europa Hexa Bolt and our lock buying guide. For inner cabinets and drawers, see the Century Pro cabinet lock.
