For work in the house I was looking for a stable arm. This is indeed originally designed to be mounted on a scaffolding pipe, but otherwise met all my requirements. The halves of the mounting assembly up and down, I have provided with very large and massive washers and fixed by two 12 mm x 160 mm each screw on a wall. Due to the washers, the load spread more diffusely on the wall. For my purposes, a good and sufficient solution. Whether the rated load of 300 or 600 kg in general or in my attachment, I can not say because I do not reach this burden. In addition, the swivel arm is provided very solid and with all the necessary screws. For the price I Besser found nothing.
