Question about tectake Electric table frame

I screwed it onto an Ikea tray that I had pre-drilled. No other system is supplied.

Of course, this is not essential, but it would be highly recommended if you don't want the plate to slip and want it to be stable. Depending on the plate, a good double-sided adhesive tape might be an option, also for attaching the power supply and control panel...

Be sure to screw tight. The control unit and the power supply unit must also be screwed to the tabletop from below.

It is essential to screw it tight, otherwise the whole thing is not stable enough.
I'm no longer sure whether the screws came with the frame.

I am very satisfied with the product and have been using it for a long time.
