Chubbsafes TRIFORCE T2

The insurable value of a safe is always an indicative guideline. It is calculated under standard conditions, for example storage in an unmonitored and unsecured building.

In practice, insurers can significantly increase coverage when additional security measures are in place, such as an alarm system, CCTV or a high-security building. This is especially relevant for the storage of precious metals, jewellery or diamonds.

That is why it is important to discuss your specific situation directly with your insurer. Together, we can determine which safe and which measures are required to ensure your valuables are fully covered.

The CD designation stands for Core Drilling and is an optional addition to the grade under EN 1143-1, just like EX or T2. A core drill is a powerful drilling machine fitted with a diamond-tipped bit, capable of penetrating even reinforced concrete. In the CD test, the product is attacked at length with this equipment: a safe with the CD option must delay the attack as long as possible, while a strongroom or strongroom door with the CD option must be able to stop it altogether. Products that pass this test carry the CD marking after their grade on the certification plate, for example Grade IX CD.

In our range, the Chubbsafes TriForce T2 can optionally be fitted with Core Drill protection, and the Wertheim vault rooms and vault doors are certified with the CD designation up to the highest grades. To see why this option is more than theory, read our article on core drill protection for safes and vault doors.

The EX designation stands for explosive resistance and is an optional addition to the safe grade under EN 1143-1, just like T2 or CD. In the EX test, a charge of solid explosive is detonated inside the safe, followed by an attack with burglary tools — and the door must remain locked. Safes that pass this test carry the EX marking after their grade on the certification plate, for example Grade V EX.

The EX test with solid explosives should not be confused with the lighter GAS test, in which a gas mixture is ignited: the pressure wave of solid explosives is many times faster and more aggressive, and protection against one type of explosion does not automatically protect against the other. EX is therefore the stricter of the two tests.

An EX-certified safe is relevant where the risk profile is highest or where the insurer explicitly requires explosive resistance. In our range, the Chubbsafes TriForce T2 and the Fichet-Bauche InviKtus are certified explosive-resistant.

The T2 designation refers to an extended tool list (Tool List 2), added in the 2019 version of the European standard EN 1143-1. During certification, safes are tested with a standardised set of burglary tools; the T2 list includes more powerful and more refined versions of these, reflecting the equipment available to burglars today.

T2 is an optional addition to the grade, just like EX (explosives) or CD (core drilling). A safe marked Grade IV T2 on its certification plate therefore offers the same certified grade, additionally tested against heavier tools. Examples in our range include the Chubbsafes DuoForce T2 and TriForce T2, certified in Grades 4 to 6 T2. Read more on our page burglary resistance classes and test methods.

The Chubbsafes DuoForce T2 and the Chubbsafes TriForce T2 are constructively related: both are certified by ECB·S to EN 1143-1:2019 T2 in Grades 4, 5 and 6, and both offer 60 minutes of fire protection for paper (NT Fire 017 – 60 Paper). Their names reveal the difference: the DuoForce protects against two risks — burglary and fire — while the TriForce adds a third: explosives.

The TriForce T2 is additionally tested and certified to the EX option of EN 1143-1: a charge of solid explosive is detonated inside the safe, and the door must remain locked. Its specifically reinforced boltwork makes that possible.

The choice is therefore simple: for most professional applications with high values, the DuoForce T2 suffices. If the risk profile is at the very highest level — banking, cash handling, critical infrastructure — or if your insurer requires explosive resistance, the TriForce T2 is the safe of choice.
