The total depth of the "Professional wall-mounted enclosure (9 U)" from Digitus is 300 mm.

The usable internal width of the DIGITUS DN-10-09U wall-mounted enclosure when the two rails are removed corresponds to the internal width of the enclosure minus the dimensions of the rails. - The internal width of the enclosure is 312 mm. - The rails are part of the 254 mm (10 inch) grid dimension construction, but the exact width of the rails themselves is not explicitly stated. However, the width of the rails is usually part of the grid dimension and not in addition to it. As the rails are integrated directly into the grid dimension and do not take up any additional width beyond the grid dimension, it can be assumed that the internal usable width after removing the rails is approximately the same width as the housing, i.e. around 312 mm. However, it should be noted that this is an assumption, as the exact width of the rails is not specified. In practice, there may be slight deviations, but in general the usable width remains at around 312 mm.

The Digitus 10" shelves listed under accessories fit. The 150mm is the depth, not the width.

From the description: The 254 mm (10") wall-mounted enclosures are made of a robust steel construction. The cable entry openings in the roof and base offer great options for neat cable management. The compact enclosure is thus ideal for all common EDP and telecommunication applications, especially in limited spaces and private households. No, this is a 10" enclosure!

Unfortunately, we do not sell it.

It is not easy to find something suitable. I have installed a Zyxel GS1100-16, mounting brackets had to be adapted because they were originally designed for 19" inch racks. Maximum enclosure width 220 mm so that it fits between the rails.

The depth size is 300mm.
