The DIGITUS blanking plate, type DN-10-BPN-01-B, is a 1 U cover for 254 mm (10 inch) profile rails in network enclosures. It is used to cover unused height units in the rack and ensures a neat visual appearance of the enclosure interior. The cover is specifically designed for the standard width of 254 mm (10 inch) and thus fits all common 19-inch network enclosures using these profile rails. The solid surface improves air circulation within the enclosure, as unused areas do not act as ventilation slots, thereby supporting the cooling of installed devices.

Cable management and rack optimisation
The blanking plate is an important component in cable management and rack organisation. It prevents cables or airflows from moving uncontrolled through empty enclosure areas, which could impair cooling efficiency. The cover is black (RAL 9005), enabling a uniform colour scheme in the server room. Dimensions are 255 mm in width, 45 mm in height, and 10 mm in depth, with the height exactly matching one height unit (1 U). These dimensions are standardised and fit all 19-inch rack systems with 10-inch profile rails.

Functions and equipment in detail
The cover is supplied with mounting hardware consisting of four cage nuts, four screws, and four washers. These components enable secure and easy installation on the profile rail in the enclosure. Mounting is done through the pre-drilled holes on the sides of the cover, with cage nuts inserted into the rails and screws passed through the plate. The washers ensure even load distribution and prevent damage to the plate or rail.

Technology explained clearly
The cover is made from a robust, flat material designed for use in server and network enclosures. The black colour (RAL 9005) is standard in IT infrastructure and ensures uniform visual design. Dimensions of 255 mm width, 45 mm height, and 10 mm depth exactly match the 1 U standard common in 19-inch technology. The 10 mm depth is sufficient to securely insert the cover into the rail without protruding excessively into the enclosure.

Compatibility and accessories
The blanking plate is compatible with all 254 mm (10 inch) profile rails used in 19-inch network enclosures. It is therefore universally applicable in server rooms, data centres, and IT infrastructures using standardised rack systems. The cover can be combined with other rack accessories such as cable ties, cable ducts, or additional blanking plates to create a complete and orderly rack structure.

Installation and mounting
Mounting is done by simply inserting the cage nuts into the profile rail and then tightening the screws through the holes in the cover. The washers ensure secure fastening without damaging the rail. Installation requires no special tools, only a screwdriver or a screwdriver combination. The cover is easy to handle and can be quickly installed in the enclosure.

Operational benefits
Using the blanking plate improves air circulation in the enclosure, as unused areas do not act as uncontrolled ventilation slots. This contributes to more efficient cooling of installed devices and can extend hardware lifespan. Additionally, the cover ensures a neat and professional appearance of the enclosure interior, which is advantageous during inspections or maintenance work. The simple mounting and included fastening hardware simplify installation and reduce effort in rack organisation.
