Using mounting brackets for your new vault door:

 

Installation:

Typically, the door frame is anchored directly into the wall using suitable mounting material through the frame.

It is essential that fastening elements are not accessible from the outside to prevent the door from being easily removed.

As you have already seen with the installation options, there are three basic installation variants that also play a role here:

A: Installation of the frame on the corridor side. Here, threaded rods are inserted and secured into welded-in threaded bushings on the back of the frame, guided through the masonry, and anchored from the inside of the room with washers and nuts. Installation using mounting brackets is not an option here.

B: Installation of the frame in the door reveal. Standard installation occurs centrally in the reveal directly through the frame profile into the reveal wall. 

However, there is also the option of flush-mounting the frame on the corridor side. Since the frame would then be close to the outside of the masonry, there is a possibility that the adhesion of the fastening elements may not be sufficient in these areas. In this case, mounting brackets can change the fastening position and provide a more stable hold for the fastening elements.

Also in cases where official requirements necessitate reinforcing a wall with insufficient masonry thickness with a pre-built wall, a central installation in the space between the two wall elements would not provide sufficient hold for the fastening elements. In these cases too, it is advisable to use mounting brackets to shift the anchoring points in the wall reveal.

C: Installation of the frame on the room side. Here too, screw connections are regularly placed through the frame profile, centrally.

Let's look at this using a photo:

This photo shows the direct installation through the frame from the room side, using chemically bonded M10 threaded rods in a hollow brick wall. 

 

To illustrate a problem, let's look at another photo from a preliminary planning stage:

As we can see in this photo, the masonry is very irregularly executed and also already damaged in many places. In such cases, a stable anchor without mounting brackets should always be critically assessed, and at the slightest doubt, we recommend using mounting brackets, which pulls the anchor points further onto the masonry. This is shown in the following photo:

The mounting brackets are made of flat steel 40x40mm with a central 12mm bore for M10 fastening elements or similar, and shift the fastening points further onto the wall.

Important to know: to meet certification requirements, a minimum of three fastening points on each vertical frame side (i.e., a total of 6 fastening points) are mandatory. 

In addition, further mounting points can be created using mounting brackets, also on the upper frame profile. These should be arranged as evenly spaced as possible, but spatial peculiarities such as an incoming step, conduits, etc., can also be taken into account; in these cases, please consult us.

Incidentally, the fastening points can also be combined, i.e., direct mounting points through the frame and mounting brackets.

For adjoining walls, e.g., in room corners, mounting brackets can also be attached to the frame in such a way that installation can take place in the adjoining wall; here, your room's conditions dictate the placement. The mounting brackets can be individually attached to the frame at any suitable position.

Now proceed to the article below and make your selection for your fastening. If you choose mounting brackets, we will of course contact you to coordinate their positioning with you:
