7 - Using mounting tabs for your new gun room door

Assembly:

The door frame is usually anchored directly through the frame into the wall using suitable mounting material.

It is essential that fastening elements must not be accessible from the outside so that the door cannot be easily removed.

As you have already seen in the mounting options, there are three basic mounting options that also play a role here:

A: Mounting the frame on the aisle side. Threaded rods are inserted and secured into welded threaded bushings on the back of the frame, threaded through the masonry, and anchored from the inside of the room using washers and nuts. Mounting using mounting brackets is not an option here.

B: Mounting the frame in the door jamb. The standard installation is centered in the jamb, directly through the frame profile into the jamb wall.

However, there is also the option of installing the frame flush with the wall on the aisle side. Since the frame is then close to the outside of the masonry, there is a possibility that the adhesion of the fasteners 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 fasteners.

Even in cases where regulatory requirements require a wall with insufficient masonry thickness to be reinforced with a facing wall, central installation in the space between the two wall elements would not provide sufficient support for the fastening elements. In these cases, too, it is advisable to install mounting brackets, thus relocating the anchoring points in the wall reveal.

C: Mounting the frame on the room side. Here, too, the screw connections are regularly placed through the frame profile, centered.

Let’s take a look at this using a photo:

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

To illustrate a problem case, let’s look at another photo from a preliminary planning:

As we can see in this photo, the masonry is very irregular and already damaged in many places. In such cases, stable anchoring without mounting brackets should always be viewed with skepticism. If there is even the slightest doubt, we recommend using mounting brackets, which pull the anchor points further into the masonry. This is shown in the following photo:

The mounting brackets are made of flat steel 40x40mm with a central hole of 12mm for fastening elements M10 or similar and move the fastening points.

Important to know: to comply with the certification, at least three attachment points are required on each of the vertical sides of the frame (i.e. a total of 6).

In addition, additional mounting points can be created using mounting brackets, including on the upper frame profile. These should be spaced as evenly as possible, but spatial features such as an incoming stair, cables, etc. can also be taken into account.

The attachment points can also be combined, i.e. direct mounting points through the frame and mounting tabs.

For walls that meet, such as in corners, mounting brackets can also be attached to the frame so that the installation can be carried out in the adjacent wall. Your space will dictate the placement. The mounting brackets can be individually attached to any convenient position on the frame.

Now go to the article below and select your mounting options. If you choose mounting brackets, we will, of course, contact you to coordinate their positioning:
