<p>The mounting is for gratings composed of tubes laid close together, having two parts clamped together, with recesses formed in one or both. Each part has symmetrical recesses widening towards their outside surfaces and whose axes coincide, on opposite sides of each tube. Each part can be formed by a U-section rail, in whose flanges the recesses are formed, the flanges of opposite rails overlapping. There can be openings in the webs of the rails opposite each other, to accommodate the clamping screws. The design ensures each tube is firmly gripped.</p> |
