StarTech.com CMBRUSH1U — 1U Brush Strip Cable Management Panel
1U · 19" rackNylon brush stripFront mountBlack steel
The StarTech.com CMBRUSH1U is a 1U, 19-inch brush strip panel that lets cables pass from the front of a rack to the back through a dense nylon brush, while the bristles close around them to keep the opening tidy. It is aimed at anyone running patch leads between a patch panel and a switch, or feeding cables through a closed rack, who wants a clean front face instead of an open gap.
StarTech.com lists it for standard 19-inch 2-post and 4-post racks and cabinets, mounted on the front rails only. The panel is steel, finished in black, and follows the EIA RS-310-D rack standard, so it lines up with ordinary 1U hole spacing.
Before you order: The box contains 10-32 and 12-24 panel screws, which suit threaded (tapped) rack rails. Square-hole racks and cabinets need M6 cage nuts and screws, which are not included. Tell us your rack model if you are unsure which fixings you need.
What's in the Box
- 1x 1U brush strip cable management panel
- 4x 10-32 panel screws
- 4x 12-24 panel screws
What It Means in Practice
- Cables pass through the brush and the bristles close around them, so the front of the rack stays neat without a wide open slot.
- A brush panel helps keep hot and cold air apart in a closed cabinet, because the gap is filled instead of left open.
- It takes one rack unit, so plan it between the patch panel and the switch where the cables need to cross from front to rear.
- It weighs only about 228 g, so it adds almost nothing to the load on the front rails.
What Will Not Work
- It does not hold cables in place or organise them into bundles. Use a D-ring or finger-duct cable manager if you need to route and support cables.
- It will not mount on square-hole rails with the supplied screws alone. You need M6 cage nuts and screws for that.
- It is not a blanking panel with a solid face, so it will not seal an unused rack unit completely.
- It is not a tool-less panel. It is fixed with screws.
Key Features
Dense nylon brush
The brush closes around cables as they pass, so the opening stays tidy with a few leads or with many.
Steel frame
A rigid steel body that sits flush on the rack rails and keeps its shape over time.
Standard 1U fit
Built to EIA RS-310-D, so the holes match normal 1U spacing on 19-inch rails.
Front-mount design
Fixes to the front rails only, so it also works on 2-post open frame racks.

Frequently Asked Questions
Can I use it on a 2-post open frame rack?
Yes. StarTech.com lists it for 2-post and 4-post racks, and it mounts on the front rails only.
Which screws do I need for a cabinet with square holes?
Use M6 cage nuts with M6 screws. The box only has 10-32 and 12-24 screws for threaded rails.
Is there a load rating?
StarTech.com does not publish one. The panel is designed to let cables pass, not to carry their weight.
Does it block airflow?
The brush fills the opening around the cables, which helps keep air from leaking through the gap in a closed cabinet.
Singular Expert Insight · Buyer's Guide
A brush panel is the simplest way to make a busy rack look deliberate: cables still go where they need to, but the front face stays closed. Pair it with a horizontal cable manager if the leads also need support, and browse our
rack accessories for blanking panels and managers in the same black finish.
✓ Buy it if you want a neat 1U pass-through between patch panel and switch on a 19-inch rack.
✕ Skip it if you need a cable manager with rings or ducts that supports and routes cables.
→ Also consider a 1U D-ring horizontal cable manager or a solid 1U blanking panel for unused spaces.
