After about 5-10 minutes the clothes rack mounting it stands stable. I have now 8 such clothes rack in use, all packed to the last centimeter and not a makes even begin a shaky impression. For mounting a wrench and a Allen key is needed, both are included. Something you have to proceed with care when assembling the plastic plugs on the sides of the hanging rail. It takes a bit of force to the plug in the bar to get, one is me and canceled because I had a little too much pressed. But there are 3 Pforpfen delivered and then breaks off a one still has a as a substitute. The 8 clothes rack I ordered in 3 orders in the rest of this I would not have done, I would not be convinced of the clothes racks.
