The Blum catalog suggests making boxes with a groove for fiberboard in all four parts, and then making cutouts in the front and back parts for the clamps. For what? It is enough to make only grooves in the sides of the box, and reduce the height of the front and back walls accordingly.

4. The front and back parts of the top drawer are 326 x 84 mm.

When mounted to the side of the cabinet, the guides are fastened by 4 mm. from the front edge of the sidewall. Hence, the minimum

the depth size (the width of the side of the cabinet) should be = Length of the guide + 4 mm. For convenience, the depth of the cabinet should be considered as follows: Length of the guide + 10 mm. In our version, with a guide length of 500 mm. the depth of the cabinet will be = 510 mm.

Kitchen box with tandembox drawers

Today we will look at making a kitchen box with a lower base with drawers. Boxes in the calculations will use tandem boxes from the Austrian company Blum. But in the article I will post my simple calculator for calculating other popular retractable systems.

I have already posted the PRO100 project of this box earlier, but I did not check the dimensions in detail in this file (it is more for designers).

So, my box has a width of 900, depth (with facade) 532 mm, height (with supports) - 830 mm. - not quite a standard size, but you can count it yourself, the main thing is to get the essence. It uses Antaro tandem boxes.

Notice

To calculate
tandemboxes, as well as other retractable systems, namely, budget metalboxes and Chinese-Polish analogues of tandemboxes - modernboxes , I use the following calculator:

Download Exel drawer calculator

Just in case, I’ll post the source code of this PRO100 box , maybe someone will need it...

Let's analyze this element in detail (the lines to the right of the number are a schematic designation of the edge - on one side or on both sides)

We will need the following accessories:

• Confirmations - 8 pcs.
• Adjustable supports H=100 mm - 4 pcs.
• Self-tapping screws 14-15 mm long - 46 pcs.
• Self-tapping screws 25-30 mm long - 25 pcs.
• Tandembox Antaro set, height N - 81 mm, depth 500 mm - 1 pc.
• Tandembox Antaro set, height C - 196 mm, depth 500 mm - 2 pcs.
• Furniture handles - 3 pcs.

Well, we bought everything we needed, ordered it and picked it up from the workshop for cutting and edging. Now you can start assembling.

Warning!

Let me make a reservation right away that the markings have already been applied to the parts. I will discuss how this was done separately, so as not to repeat it with each new box.

You should start by marking and installing the guides on the racks. On the front edge of each rack, first set aside the height of the facades (along with the spaces between them). Considering that the bottom of our box is overhead, we must subtract 16 mm (bottom thickness) from the first size. It turns out

268 - 3 - 284 - 3 - 150 - 5 mm.

Then we move on to the actual marking of the guides. 33 mm is set aside from the bottom edge and bottom border of each façade. We draw a perpendicular to this point, after which we mark 37 mm on it. We prick the point with an awl.

This is the center of the third hole in the guide. That is, we lay the guide on the line so that it can be seen through the holes. We screw the self-tapping screw into the third hole (at the marked point, of course). Then we align the guide again so that the marking line passes through the centers of all the holes and screw a couple more screws into it.

As a result, we should get a picture like this, only in pairs. (in mirror image, of course).

Let's start assembling the box. Using four confirmats, we screw the racks to the bottom (it's better to do this by placing the box on its back). This way we can see the ratio of parts and, if necessary, correct it).

Again we fasten the body strips with confirmations (the edge is directed forward).

Now we lay the box on the front side, put the back wall on it, align the walls with the edges of the fiberboard and temporarily fix it with three nails (or self-tapping screws) so that it does not move. Then, using a thin drill, we drill holes for the screws and fasten the wall to the box.

We turn the already almost assembled rigid box “on its head” and screw the legs. It is advisable to mark and mark the attachment points for self-tapping screws in advance.

In general, the finished box looks like this.

Let's move on to assembling the drawers themselves. First, we screw a pair of side clamps to the back wall. The top edge of the chipboard part (where there is an edge) should be flush with the metal part. If it doesn’t work right away, the mounting holes have an oblong shape and allow you to make adjustments within a couple of millimeters.

We attach the side walls to the rear wall; to do this, we snap them onto the latches of the rear wall (put them into the grooves and press them into place.

Having snapped both side walls into their proper places, we insert the bottom into the grooves on the underside of the walls.

We turn the box over, and pressing the side to the bottom with one hand, screw the screws into the mounting holes (23 pieces per side).

We collect the remaining boxes in the same way. (we are not installing roof rails yet - they are installed together with the facades).

We install the drawers on the guides. To do this, we simply pull out the last ones, place the drawers on top and push them all the way. At a certain moment, a metallic clang will be heard and the box will clearly fall into place.

The next step will be the installation of facades. First, we mark them out. In the photo I show the markings of the lower and other facades; they differ from each other, because the lower one also covers the bottom of the box. The two lower holes are for fastening the facade itself, while the upper one is for the railing.

Use a 10 mm drill to drill blind holes 12 mm deep. It is better to do this on a machine or use any drilling depth limiter, otherwise it can be very sad.

After this, we take the holders in our hands (at rest they are bent to the side), insert them into the lower pair of holes and straighten them (thus, they are fixed at random). I must say that it is quite tough.

We put the façade in place. To do this, simply click the holders into the side walls of the tandembox.

Now for deep drawers you need to install rails. They are attached to the facade in the same way as holders, that is, they are placed in the holes and straightened.

The railing is attached to the rear wall with a snap. It is placed on the “notched” corner and snaps downwards.

By rotating the orange part of the railing you can adjust the tilt of the facade. All these adjustment devices are locked by sliding the plastic coupling forward, again until it clicks.

We install all the other facades in the same way.

All that remains is to make the adjustment. For this purpose, there are adjusting screws and slots (for a Phillips screwdriver) on the side walls of the tandembox.

As a result, the box takes on this form. All that remains is to screw on the handles, which haven’t even been chosen yet)))

Easy installation without tools

The various TANDEMBOX plus designs are easy and convenient to install. Adjustment in three planes allows you to create the perfect façade pattern. And all this without a tool.

Installation, adjustment and dismantling

Once the façade fastening is installed, the façade simply clicks into place.

All components can be installed quickly and easily without tools.

Adjustment in height and width is conveniently carried out through a window in the drawer. The tilt adjustment is carried out directly on the railing.

How to install blum tandem boxes correctly

Hello dear friends.

Today we will talk about what retractable systems with a “self-driver” are and how they are installed.

In our example, it will be a tandem on a box, 440 mm deep.

To begin with, I will say that for this fittings, there are special catalogs that indicate all their sizes and installation diagrams.

So, for tandems, the drawer is designed differently than for conventional guides (for example, for the same “telescopes”).

The height of its side parts should be 12mm greater than the height of the transverse parts.

Special mechanisms are attached to the resulting protrusion (from the front end of the box) (in the photo, they are red).

Its total width in this case is also greater than the standard width, since it does not depend on the gaps on the guides, the size of which is usually, as you know, 13 mm.

In this case, this gap will be 5 mm.

So, special mechanisms (latches) are mounted on the front edge of the box, and holes are made on the back edge, thanks to which it is fixed in a special mechanism.

Next, at a distance of 37mm from the front edge of the side, guides are attached to the side itself. In this case, the box contains one telescopic guide (upper) and two “tandems” at the bottom.

After assembling the box, the box is very easily inserted into the system and works great.

In addition to the fact that the Blum tandembox is a system with a self-winding mechanism, it (according to the instructions) can withstand quite a decent weight.
