STACKE Xcalibur – premium burglary-resistant safe (Grade 5 & 6, EN 1143-1, ECB·S, VdS)
The STACKE Xcalibur is a premium burglary-resistant safe, officially certified by ECB·S and VdS in accordance with the European standard EN 1143-1, Grade 5 and 6. These certifications confirm an exceptionally high level of reliability and resistance against both mechanical and thermal attacks.
Each Xcalibur is built with a multi-wall steel construction, reinforced with armour plates, internal reinforcements and a core made of UHPC (Ultra High Performance Concrete). The door features a three-fold interlocking joint, improving both fire protection and burglary resistance by securely interlocking the door with the safe body. A reinforced profile along the full height of the door protects against forced opening on the hinge side, while large flat steel locking bolts further increase resistance. Two patented relockers automatically block the locking mechanism in the event of an attempted break-in.
The STACKE Xcalibur is equipped as standard with CD protection against diamond drilling, providing maximum protection against highly advanced burglary techniques.
Various locking configurations are available, including key locks, mechanical combination locks and electronic code locks, all certified according to EN 1300. In accordance with the standard, all Grade 5 and Grade 6 models are equipped with at least two certified locks. The interior, with smooth walls and adjustable shelves, provides maximum flexibility and ease of use.
The Xcalibur range includes several models in Grade 5 and Grade 6 and can be extensively customised to meet specific requirements. STACKE therefore provides high-security solutions for the most demanding applications in banking, industry, public administration and high-end residential environments.
The models shown here represent only an overview of the standard range. STACKE also develops safes, vault doors and strongrooms up to Grade XIII, combining the highest levels of security with uncompromising German engineering.
