This bay is really good quality but be careful, for this model, the center distance between the hardware fixing uprights is 23.5 cm. Unlike 19-inch bays, 10-inch bays do not have standardized dimensions. There are therefore 10-inch bays with different centers between the fixing amounts of the rackable equipment, i.e. 25.4 cm or 23.5 cm. The equipment of one cannot be fixed in the other. The 25.4 cm indication mentioned in the ad is misleading, and my request for information, by telephone and email, was not understood. I was forced to return my order as my equipment with a 25.4 cm center distance did not fit into this bay. The free return is very appreciable in this case, just a waste of time. The bay has no ventilation in the lower part but it is possible to open the wire passage hatch, if necessary. (Simply screwed which is a plus to facilitate its opening).
