227 locking drawer slides

You don't need to separate them, just slide them open and attach the draw to the inner slide on both sides then attach the main part to your frame. This is what I did.

If you do want to seperate the two parts, extend the slide to full extension and on the outer part , half way out, there will be a small black plastic lever. The slides are opposite set, so one lever goes up and the other goes down. Move the lever and pull the inner part, the one which attaches to the drawer, out from the outer part of the slide. To reattach, just line up the two parts and push together.

The 227kg do not come apart. It does not have the plastic tabs like the 125kg and smaller
There will be holes in the slide you need to line up to put the screws or rivets in

I have installed two sets of these slides with a heavy weight on them and they failed both times. So do be aware that the actual working load is vastly less than the 227kg claimed.

Some come apart and some don’t. As above they usually have black tabs to release the slides, otherwise just move the slide out to line up the mounting holes.
Note that the 227kg is only in the closed position. At full extension it would lucky to be half of that. The specs usually have a table or graph showing weight limits at different extension lengths.
