I have to rely on the other reviews and was not disappointed. Massive square inserted in square tube. Thumbscrews fall into countersunk screw locations in the solid rod and let such a good height adjustment to. Easy adjustment of the chain in a cut cylinder at the top. A proposal to optimize I: On a leg a small pin should be mounted so that the handle of the chain is not perpendicular to the fireplace, or the grate or boiler depends, but can be fixed to a leg side. This can be determined but somehow improvising, if you value it.
