How much weight can a drawer with these runners hold?
One set of these drawer runners can carry 200kg. This applies in both retracted and extended position and if the weight is evenly distributed over the length. If the weight is only going to be placed deep in the drawer, these guides can carry approximately 115% = 230kg. The maximum point load in the front of the drawer is close to 70% = 140kg. Do not forget to include the own weight of the drawer in your weight calculation. If necessary, place dividers in the drawer to prevent heavy contents from sliding forward. This benefits the drawer slides. You can also choose not to have the drawer guides extend to the maximum, but to have the movement stop sooner. You thus limit the arm of the protruding weight, so that the guides can handle a greater load compared to a maximum extension.
Upright or flat mounting of drawer slides?
The 200 kg evenly distributed load applies if the drawer slides are used standing, or mounted against a side. It is possible to mount the drawer slides flat under a drawer, but this is disadvantageous for the deflection and the weight to be carried. When fully extended, the drawer runners bend much more in a horizontal position than if you mounted them upright. You also have to take into account a 60% decrease in the weight to be carried, so 200 kg standing becomes 80 kg lying down.

Drawer guides with lock
We can supply our heavy duty 200kg drawer runners with or without a lock. The variant with lock does not fall open unintentionally and you have to push a lever to unlock the movement. The drawer slide locks at two different times; fully closed and fully open. A set includes a left and a right drawer slide of which only the handle differs; of one guide the handle points upwards, of the other downwards. This is necessary because drawer slides are mounted mirrored and the handles must point in the same direction in that situation. You must decide for yourself whether it is easy for your application to point the handles downwards or upwards. Personally, I find it easier to push the lever up for unlocking.
In some cases it is desirable if only one of the two guides locks the drawer. For example, with a wide drawer where the drawer guides are far apart. In that case it is not possible to operate both levers simultaneously.
It would be easier if you could order one drawer runner with and one drawer runner without a handle. Unfortunately this is not possible, but what is possible is to combine two sets. So you could purchase one set with and one set without handles and process one drawer guide from both sets per drawer. You can make two drawers that can both be operated with one handle.
What does 3-part extendable mean?
There are 2-part and 3-part drawer slides. The difference lies in the extendability of the conductors. Drawers with 2-part drawer guides can be partially pulled out, while drawers with 3-part drawer guides can be slid completely outside the casing. Fully extendable. This makes it easy to grab things in the back of the drawer as well. Our range only contains the most user-friendly variant; the 3-piece drawer runners.
Fixing drawer slides at right angles
With the help of our corner mounting brackets, these drawer runners can be mounted at an angle of 90° to the floor or ceiling. We offer these aluminum mounting brackets in two versions; untreated and with black powder coating. If desired, you must add one of the two separately to the shopping cart.
The brackets can be attached to the drawer runners in two ways; you can choose to attach the horizontal lip under the drawer to the bottom, or to have it stick out on the side beyond the drawer guides and screw it against the bottom. In addition to the brackets, compact fasteners are also part of the mounting set. With the aid of this, the drawer guides can be attached very neatly to the aluminum brackets. There are no sharp wire ends protruding anywhere, so that the brackets can be placed close to a wall. It is also possible to attach two drawer slides to one bracket with which you can realize two connecting heavy duty drawers. Ideal for a double drawer in the back of a company bus or camper!
Do I need a ball or roller guide?
If you want to achieve a smooth and accurate movement, it is best to opt for a ball guide. There are many small balls between the slides of a ball guide that can absorb both vertical and horizontal loads. A roller guide, on the other hand, functions by means of rollers (wheels) over a rail and can mainly handle vertical loads. There is also a difference in friction. Bullets have point tangents and roll line tangents, creating more friction. For these two reasons, BRASOM Drawer Guides has made the conscious choice to focus solely on high-quality ball guides.
