... The processing:
As Matthias Haas I drilled the wood even briefly. A 0815 4p Holzbohrer the times for 2-3 mm is prepared sufficient. Subsequently, the screw of Filzgleiters goes wonderfully flowing into the wood. For a full dining table set you need for less than five minutes.
The quality of materials makes a very good impression. The screws go into the wonderful (solid) wood, the metal flakes have no sharp edges, and the slider fulfill completely their purpose. For the price you can absolutely not complain, and I do not regret to have bought a few more directly on stock.
Short side Info:
Initially, until compresses the felt, the amount of the slider is about 1cm. The screw has about a depth of almost 2 cm.
