Frequently asked questions

Atelier Boonen takes care of the delivery, installation and anchoring of safes entirely in-house. We never use external transporters or installers. Using specialised transport equipment, we deliver discreetly and safely, including to upper floors or hard-to-reach locations. Safes are always wrapped in opaque film and transported in unmarked vehicles to avoid curious eyes.

For safes up to 1000 kg, anchoring is mandatory under the European standard EN 1143-1. We carry out this anchoring carefully, using chemical anchors or adapted solutions depending on the substrate. Where necessary, we use stair climbers and protective materials to safeguard floors, walls and staircases.

The installation is always carried out safely, efficiently and with respect for the building. This guarantees you a professionally executed installation offering the strongest and most durable solution. In 95% of cases, delivery, installation and anchoring are included in the price — at no extra charge.

A burglary-resistant safe is a security cabinet specifically designed to withstand burglary attempts. These safes are tested according to the European standard EN 1143-1, which measures resistance against attack methods such as drilling, grinding, prying and thermal tools.
Based on these tests, each safe is assigned a resistance grade:

A safe with a code lock is also known as a digital safe or combination safe. Locking is done by an electronic code lock or a mechanical combination lock. Key-operated safes are also available, as are combinations of both. The right choice depends on your daily use and the security grade of your safe.

From grade 4 onwards, two safe locks are mandatory — a combination of key lock and code lock, or two code locks. For lighter safes, a second lock can be added as an option.

  • Electronic locks: user-friendly, the code is easy to set and change, often with multiple codes, time functions, audit trail and alarm connection.
  • Mechanical locks: the classic mechanical dial lock — extremely reliable and durable, less prone to faults, but slower to operate and more complex when changing the code.
  • Key locks: suitable as an additional lock, but rarely recommended as the only lock.
