Solid blanking panels are the best choice for covering unused rack spaces and limiting hot-air recirculation; choose a brush panel when cables must pass through the opening. The Rackstuds EZIBLANK options suit operators who want snappable panels for different rack heights, while StarTech is a straightforward choice for a 19-inch rack and tool-less installation. Zonon combines a brush opening with cable access. Tecmojo is designed for 10-inch racks, not standard 19-inch racks.
| Product | Best For | Rack Type |
|---|---|---|
| Rackstuds EZIBLANK, 10 sheets | Flexible coverage across rack spaces | 19-inch |
| Zonon brush panel, 2 pack | Cable pass-through | 19-inch |
| Rackstuds EZIBLANK, 2 sheets | Smaller supply of snappable panels | 19-inch |
| Tecmojo vented panel, 2 pack | Unused space in a compact rack | 10-inch |
| StarTech tool-less panels, 10 pack | Quick installation in a 19-inch rack | 19-inch |
Rackstuds EZIBLANK 10-Sheet Panels
This box contains 10 sheets of 6-RU EZIBLANK panels. The panels are designed for square mounting holes in EIA-310-D-compliant 19-inch server racks. Their snappable construction lets operators separate sections and reuse them to cover different amounts of unused rack space.
Best for: Data center teams that need a larger supply of adjustable solid panels. The product is selected for its stated snap-apart design and rack compatibility, which can help match panel coverage to varied open spaces. The solid coverage is intended to limit mixing between hot exhaust air and cool intake air.
Limitation: These panels cover openings, so they are not the right choice where cables need to pass through the same rack space. Confirm the rack uses the specified 19-inch EIA-310-D format.
Zonon 1U Brush Panels, 2 Pack
Each Zonon panel is a 1U, 19-inch rack-mount cable management panel with a dense nylon brush strip. Cables can pass through the brush opening while the strip acts as a barrier against dust and contaminants. The panel is made from cold-rolled steel with a black powder-coated finish.
Best for: Racks where cable routing must remain open while the operator wants to reduce bypass airflow through the opening. It is included because it offers a different function from a solid blanking panel: cable access rather than a fully covered face.
Limitation: A brush strip does not close the opening as completely as a solid blanking panel. Choose a solid panel instead when the rack space does not need cable pass-through.
Rackstuds EZIBLANK 2-Sheet Panels
This EZIBLANK box contains two sheets of 6-RU panels and is described as having tool-less installation. Like the other EZIBLANK option, it is designed for square mounting holes in EIA-310-D-compliant 19-inch racks. The panels can be snapped apart and reused in different rack-unit heights.
Best for: Buyers who want the EZIBLANK snap-apart format but need a smaller listed quantity than the 10-sheet box. It provides the same stated flexibility for filling different sizes of unused rack space.
Limitation: The listed box contains fewer sheets than the 10-sheet option, so it may be less suitable for covering many openings. Check the required total rack-unit coverage before selecting a pack.
Tecmojo Vented 1U Panels, 2 Pack
Tecmojo’s two vented panels are 1U and made for standard 10-inch server racks and network cabinets. The cold-rolled steel construction has a black electrostatic powder-coated finish. The product description says the panels cover unused space and help protect equipment from dust and debris while supporting airflow.
Best for: Owners of 10-inch racks who want a vented filler panel for an IT closet, AV rack, data center, or home lab. It is included as a compact-rack option, not as a substitute for a 19-inch panel.
Limitation: The product information explicitly says these panels do not fit 19-inch racks. Their vented design also differs from a solid panel that fully covers an opening.
StarTech Tool-Less 1U Panels, 10 Pack
This 10-pack contains solid 1U blanking panels for 19-inch racks. The tool-less design latches onto standard 19-inch rack equipment, and the panels cover open spaces and exposed cabling for a more uniform rack layout. Their solid design is intended to support airflow management by closing unused rack openings.
Best for: Buyers who prefer individual 1U panels and want a tool-less installation method. The pack format can suit operators filling multiple separate single-unit gaps.
Limitation: These are fixed 1U panels, rather than larger snappable sections. Measure the open spaces and confirm the rack format before ordering.
Buying Guide: How To Choose Data Center Blanking Panels
Should you choose solid, vented, or brush panels?
Choose solid panels for unused openings where cables do not need to pass through. They are intended to separate hot exhaust air from cool intake air. Choose a brush panel when cables must cross the rack face. A vented panel leaves ventilation openings, so it is not equivalent to a solid blank for closing an unused space.
Does rack width matter?
Yes. Check the rack width and mounting-hole format before buying. The EZIBLANK and StarTech listings specify 19-inch racks. Tecmojo specifies 10-inch racks and explicitly excludes 19-inch racks. Do not assume that a panel fits based only on its 1U height.
How much rack space should a panel cover?
Measure the height of each opening in rack units. Individual 1U panels suit separate single-unit gaps. The EZIBLANK sheets can be snapped apart and reused in different RU heights, while the 10-sheet and 2-sheet boxes differ in quantity. Estimate how many openings need coverage before choosing a pack.
What else should you check?
Consider installation style, cable access, and panel material. Tool-less latching can simplify installation where compatible with the rack. A brush opening allows cables through but does not provide the same closed face as a solid panel. Review the product’s stated rack compatibility and construction rather than assuming all rack panels are interchangeable.
Frequently Asked Questions
What do blanking panels do in a data center?
They cover unused rack openings. Solid panels help limit the mixing of hot exhaust air with cool intake air, supporting more controlled airflow through rack equipment.
Are blanking panels the same as brush panels?
No. Solid blanking panels cover openings, while brush panels allow cables to pass through a brush strip. Select based on whether the rack space needs cable access.
Will a 10-inch panel fit a 19-inch rack?
Not necessarily. The Tecmojo product is specified for 10-inch racks and says it does not fit 19-inch racks. Verify the rack size before purchase.
What is 1U in a rack panel listing?
1U identifies a single rack-unit height. A 1U panel is intended to cover one rack unit of vertical space, while the EZIBLANK sheets can be separated for different RU heights.
Should every open rack space be covered?
Cover openings that are intended to be closed for airflow management, while accounting for required cable routes and equipment ventilation. Use a brush panel when cables need to pass through an opening.
