Disec MR423: A defender designed well but sold poorly.

How is the Disec MR423 composed?

Today we are talking about the magnetic protector for Dierre European cylinder locks with a security grade 4. This defender replaces the traditional 42 mm defender fitted as standard on Dierre brand armored doors. Its body is made entirely of steel, but the central part is made of stainless steel. This version produced by Disec is a really effective product but only if it is sold with the right criteria.

The Body

The Disec MR423 is similar to the MR500 version, with a smaller size of 42 mm and not 50 and is sold without any strain relief device, the front rotating part is made of stainless steel. Inside it is a combination of magnets and positions. These combinations create really special and complex cipher systems. Thanks to its stepping technology, the key is interrogated several times during rotation, ensuring extreme protection against manipulation.

The filling function

Key plugging is done by a rotation of the plate made of stainless steel operated by its key made with a combination of vectors and positions. These details give the defender a high degree of security with an unparalleled system of operation. And thanks to the protections and details with which it is made, drilling is a distant memory. Its details and materials make this accessory an excellent deterrent against acid.

The reason why he was born

Disec MR423 was created with a very specific purpose, namely to facilitate the securing of a Dierre lock security door as long as it has the anti-intrusion system, this is for the simple fact that it does not have any anti-intrusion badge but is to be sold bare and then to be combined with the traditional Dierre badges with plastic underplate.

Factors to consider:

Although perfectly designed, this product has some details to consider:

It should always be combined with cylinders that have key necks at least 15 mm long.

ALWAYS make sure that the lock on which it is installed has the locking device that is activated when the defender and cylinder are broken, otherwise you will incur changes and expenses made unnecessarily.

Even if you choose gold and bronze finish the defender will always have the central part made of hardened stainless steel in steel color.

For added security remember to always close the defender, because if we leave the defender open we make this shutter keyed.

This defender was created as a key shutter and not as an anti-knockout protection so evaluate well the degree of security you want to achieve.

Verify that you purchase the defender with the appropriate escutcheon with depth suitable for your door.
