Wall vases that can be mounted on 20x20 profiles. They have a locking system that allows you to raise or lower them as you wish and then lock them via a screw system. To mount them you need to insert an M3 threaded insert inside the holes, one in the pot and the other inside block 1, then through 2 M3x12mm screws mount everything. Block 2 is a little hard to insert but it should fit into the pot, this is the block that secures the pot to the profile. The screw holder is simply used to more easily fix the screw to the vase to block it. If you need more information for assembly, please write to me
