Window Broken – What to Consider When Buying Spare Parts?

Who doesn't know it? Just before holidays and long weekends, something tends to break. Older windows also tend to break at inconvenient times.

The window can no longer be properly closed or opened. It quickly becomes clear: something is wrong with the window fitting. In the digital age, no problem. A quick surf on the net and a few spare parts for window fittings are found. However, the problem often lies in the details. This guide is intended to help you pay attention to the most important points so that there are no unpleasant surprises upon delivery.

1. The right manufacturer

Each manufacturer builds its own fitting system, which only harmonizes with itself. These systems are not interchangeable. Roto, Maco, or Gretsch-Unitas as reputable manufacturers can be recognized by their embossed logos on the fitting.

2. Determine the correct spare part

Next, we need to identify the exact component on the window that is broken. There are numerous individual parts on a window. A list of all possible components can be found in the Tooler online shop.

It often affects the corner drives, gears, or corner bearings and bands. This is often due to the many moving parts.

3. Take the correct measurements

Now, for some spare parts, it is important that we order the correct size. The two measurements sash rebate height (short SRH) and sash rebate width (short SRW) are most commonly needed.

It is important to know in advance that a window consists of a frame (fixed in the masonry) and a sash (usually tiltable and turnable). The fittings of the defective window are installed in the so-called fitting groove.

Sash rebate width: We measure on the opened sash from the left to the right outer edge of the fitting groove. The total measurement is called the sash rebate width.
Sash rebate height: Analogous to the sash rebate width, we measure from the bottom to the top outer edge of the fitting groove.
Please note: Some spare parts have a variable size and can therefore be used for a wider range.

4. Determine the DIN direction

Often, when buying spare parts for a broken window, we need to specify a DIN direction. This indication tells us in which direction the window sash opens. We differentiate between DIN-Left and DIN-Right, determined by looking from inside at our window:

DIN-Left: The window handle is on the right side and the corner bands or hinges are on the left side.
DIN-Right: The window handle is on the left side and the corner bands or hinges are on the right side.

Note: For parallel slide-tilt doors and lift-slide doors, the DIN direction is determined by the handle side on the inside!
If the handle is on the right side, we speak of a PSK or lift-slide door with DIN Right.

5. Summary

The right manufacturer and the correct size are fundamental to buying spare parts for a broken window. Finally, compare the technical drawings of the online shop with your component.
