Hello,

Thank you for being so interested in tools suitable for USM furniture.

I am Benjamin Stahl and an enthusiast for system furniture.

The furniture can be adapted to your living situation and converted accordingly. I make these special tools so that you too can expand, move or dismantle your furniture.

I have compiled information on the following topics:

I hope that I can help you with this information and clear up any confusion.

Dismantling the furniture

What tools are available?

I offer two different basic principles.

The plug-in systems are ultra compact, fit in every tool case, are always with you and even tight spaces and ceiling heights are no problem for this type of tool. I offer the variant in:

Basically, all of my tools can be used for assembling or disassembling furniture. For example, the long wrench can be used to loosen the screws on short pipes, but it is much more comfortable to work with the more extensive sets and the wrench in the "right length". This saves time and nerves in the heat of the moment (moving).

Still unsure which tool you really need? Here is an overview with pictures and further information.

My tool doesn't fit!

I can assure you that the tools fitThe furniture has been sold with the exact same screw for +30 years.However, there is one detail that always causes confusion: the screw has an opening for a hexagon socket on both sides.On the "screw head side" there is a 5 mm hexagon socket. On the “thread side,” there is a 4 mm hexagon socket. The threaded side is screwed into the corner balls. To loosen the screw through the ball, you can simply loosen the screw through the ball using a standard 4 mm hexagon socket. !!! Attention, pay attention to the direction of rotation!!!. To loosen the screw through the hexagon socket, turn it clockwise in a different direction than usual.
We can only get to the screw head side by driving the tool through the pipe. The special tool “the long Allen key” is used here. To loosen the screw, turn it counterclockwise as usual.

How do I dismantle the piece of furniture?

The best way to proceed is as follows:

Point 4: Loosen the screws through the balls (clockwise)

Point 5: Loosen the screw through the pipe (counterclockwise)

1st generation or 2nd generation?

From around 1990 there was a fundamental change in furniture. The change affected the expansion elements (connecting elements) in the tube.

Both connectors use exactly the same screws. For this reason, my tool is compatible with all USM furniture.

Only my magnetic connector puller is only compatible with the second generation.

It is easy to see which generation you are dealing with if you loosen the screw through the ball and compare it with these pictures.

Can I split the furniture in the middle?

Normally no. Unfortunately you have to completely dismantle one half. There is an exception if a "slotted pipe" has been installed. These slotted pipes have a recess at the end of the pipe so that you can get to the screw heads even when the pipe is installed. Maybe you'll be lucky. If not, it might make sense for you to get these slotted pipes for the subsequent assembly and place them in strategically favorable positions.

My screws won't come loose!

Sometimes the screws are really tight. This is usually because:

Please remember: Loosen the screw through the ball clockwise.

Through the pipe anti-clockwise.

If the screw cannot be loosened with the small Allen key provided, I have included an Allen bit. You can grab and turn this with a ratchet from any socket box or with a pipe wrench. Using an impact wrench for disassembly, if you have one, is also fine, as long as you pay attention to the direction of rotation. As soon as the screw is loosened a little, you can use the small Allen key again.

The connector cannot be removed!

Sometimes the connectors get jammed in the pipes. This often happens when the screws are tightened very tightly or when they have not been opened for a long time. If the connectors are jammed, I have prepared a video for you on how to release the jam. It works best with a rubber hammer, which gives an "impulse" to the pipe so that the pipe deforms briefly. Don't worry, the pipe is so stable that it immediately springs back to its original state, the "wedges" in the connector are moved and released.

How do I install and remove the shelves?

First press in one side (left or right). Then press in the other side (hit with the flat of your hand or with a rubber hammer if necessary)

Which adapter do I need for what?

T or L-key set

It's very simple for the T and L keys. The long T or L keys are for loosening or tightening the screws through the pipe (5 mm hexagon socket).

The small hexagon socket key or the hexagon socket bit is needed to loosen the screw through the ball. If you don't have a ratchet, the hexagon socket bit can be held and turned using a pipe wrench, for example.

The connector puller can simply be put on the T or L key. It can be used to pull the loosened connector out of the pipe. You can read how to loosen the connectors in the "The connector cannot be loosened!" section.


Plug-in tool

With the plug-in tool, the ratchet must be connected to the extension. The hexagon socket insert is then attached. The screw can now be opened or tightened through the pipe.

The small hexagon socket wrench or hexagon socket bit in the bit holder is needed to loosen or tighten the screw through the ball. The hexagon socket in the bit holder can be used with the ratchet instead of the extension.

The connector puller can simply be put on the hexagon socket insert. The loosened connector can be pulled out of the pipe with it. You can read how to loosen the connectors in the section "The connector cannot be loosened!"

Riveted intermediate struts/cross beams on the shelves?

Does the piece of furniture have riveted intermediate struts/cross beams between the shelves?

The cross beams were previously used for a hanging file drawer. The struts are riveted to the front and rear tubes. This means that they can only be dismantled as a whole. You can replace the relevant tubes or reinstall them as a whole. The floor shelves also have a notch for the rails. These can continue to be used as long as the easily visible recesses do not cause any problems.

Dismantling the slotted pipes

This video shows how to remove the slotted tubes.

Simply use a 5 mm Allen key with a ball head to open the screws through the slotted tubes.

Can I dismantle tables with the tool?

Unfortunately not. The tool is only suitable for furniture with balls as corner connectors.

For the tables with two legs in the KITOS series, a 10 mm Allen key with a length of approx. 500 mm is required. This can be done with a standard extension from a socket box.

For the standard tables with four legs, an 8 mm Allen key is used if there is one screw or a 6 mm Allen key if there are two screws. Any Allen key from an Allen set from the hardware store can be used here. A suitable video can be found here on YouTube


Assembly of the furniture

Assembly of the body + shelves

The best way to proceed is as follows:

Installation of the slotted pipes

This video shows how the slotted tubes can be installed.

Simply use a 5 mm Allen key with a ball head to close the screws through the slotted tubes. If you are planning to move house in the future, I recommend using the slotted tubes to divide the furniture into manageable units.

General information about the furniture/components

What components are there?

There are four types of tubes:

They are available in the following system dimensions: -100mm -150mm -175mm -250mm -350mm -395mm -500mm -750mm

(The system dimension is the distance from ball center to ball center, the actual tube length is approx. 18 mm shorter than the system dimension.)

There are three variants of connectors.

There are basically the following versions of shelves:

There are two types of hinges for folding doors:

Slide-in flap hinges are folded upwards and the flaps are then pushed in at the top. They are available in two versions:
