Rittal DK 7151.305 Blanking Panel, 3U, Tool-Free, Pack of 3
3U = 3 × 1UTool-freePack of 3UL 94 HB
The Rittal DK 7151.305 is a 19-inch blanking panel, 3U high and divisible into three 1U sections, that clips into the rack with integral quick-fasteners and no tools — supplied as a pack of three panels in matt black RAL 9005 plastic.
Blanking panels close unused rack units so that cool air is forced through your equipment instead of short-circuiting around it through the gaps. In a partly filled rack that is one of the simplest ways to lower equipment temperatures. Each panel can be split into 1U pieces, so one pack covers gaps of 1, 2 or 3U.
Before you order: Rittal specifies the panel for the 482.6 mm (19") mounting level but does not list specific enclosure series. It is plastic and non-load-bearing: it only covers space, it does not hold equipment.
What's in the Box
- 3 × blanking panels, 3U (each divisible into 3 × 1U), with integral quick-fastening
What It Means in Practice
- Close every empty U in the front of a rack to stop hot exhaust air being drawn back into the equipment intakes.
- Split a 3U panel into 1U pieces to fill single-unit gaps between switches and patch panels.
- Tool-free fixing: the panels clip in and can be removed again when you add equipment.
- A pack of three gives up to 9U of coverage.
What Will Not Work
- It will not support any weight — do not rest equipment on it.
- It is not a vented or brush panel; for cable pass-through use a brush panel instead.
- Rittal does not publish fit for non-19" or 10" racks.
- It will not fit where the 19" rail has no square or system punching for the clip.

Rittal specifies the 19" mounting level only. Send us your rack model and we will check the rail punching.
Singular Expert Insight · Buyer's Guide
Blanking panels are the cheapest cooling upgrade in a rack: without them, hot exhaust air loops back to the front and switches run hotter than they need to. Fill all gaps, not just the big ones. Pair them with a brush panel where cables need to pass — see our
rack accessories range.
✓ Buy it if you want to close empty units in a 19" rack quickly and without tools.
✕ Skip it if you need cable pass-through (use a brush panel) or a load-bearing shelf.
→ Also consider a 19" brush panel for cable entry points between patch panels and switches.
Tell us your rack model and how many empty units you have, and we will suggest the right mix of panels.
