Detailed specifications and benefits
This shelf is engineered to fit 19" (483 mm) standard racks and takes up a single rack unit height, preserving valuable vertical space for other equipment. The usable depth of 300 mm is chosen to suit many compact devices found in modern racks—such as small switches, media converters, compact UPS bricks and cable management modules—without protruding into the equipment bay or restricting airflow.
Built from steel (typical sheet thickness 1.0–1.6 mm depending on manufacturer), and finished in a black powder‑coat (commonly near RAL9005), the shelf resists corrosion and wear while maintaining a neat, professional appearance. The cantilever/front‑mount method simplifies installation: the shelf attaches to the front posts and provides a stable platform that doesn’t require rear mounting in many standard setups.
Benefits of this design include:
- Space efficiency:The 1U height is a compact solution for when every rack unit counts.
- Ease of access:Front mounting and an open cantilever layout make it straightforward to place and remove devices, manage cables and perform maintenance.
- Durability:Steel construction and powder‑coat protection extend the useful life even in busy cabinets or workshops.
- Flexibility:Suitable for a variety of lightweight devices and accessories—ideal where sliding or vented shelves would be overkill.
- Cost-effective:A simple, affordable accessory solution for small installations or as part of larger rack builds (suggested retail around £34.99, model dependent).
- Rack units: 1U (≈44.45 mm).
- Compatible width: 19" (483 mm standard rack).
- Usable depth: 300 mm.
- Material: Steel (typical 1.0–1.6 mm sheet).
- Finish: Black powder‑coat.
- Mount type: Cantilever / front‑mount.
- Typical max load: Generally 10–25 kg for similar shelves—verify exact rating with supplier ITM001147 before critical use.
- Included hardware: May include cage nuts / basic fixings — confirm contents with the supplier.
Use cases and scenarios where this shelf excels
The 1U 300 mm cantilever shelf is especially well suited to environments and tasks where compactness, quick access and tidy cable routing are priorities. Typical scenarios include:
- Small office and comms racks:Housing small switches, PoE injectors, compact routers and other devices that don’t require a full-depth shelf or mounting ears.
- Patch panel support and accessory storage:Holding cable management accessories, spare patch leads, labelling tools or small punch‑down tools near the patching area for convenience.
- AV equipment racks:Supporting compact AV processors, power bricks, or adapters close to the front of the rack for easy access during events or servicing.
- Retail or point‑of‑sale infrastructure:Organising small power supplies or network extenders inside counters or back‑of‑house racks where space and appearance matter.
- Temporary or test setups:Quick installations in field trials or test racks where you need a stable platform for devices without permanent mounting.
Because the shelf is shallow and accessible from the front, it also helps keep cables neat and reduces the need to reach deep into racks—reducing downtime during maintenance and making device swaps faster.
Comparisons with similar products
When selecting a rack shelf, several types are available. Here’s how the 1U cantilever 300 mm shelf compares to common alternatives:
- Fixed full-depth shelves:Full-depth shelves provide greater load capacity and support for deep equipment, but they consume more vertical space and can be unnecessary for small devices. The 1U cantilever shelf is more space‑efficient for compact items.
- Vented/Perforated shelves:Vented shelves improve airflow for heat‑generating equipment but are generally deeper and intended for heavier loads. The cantilever shelf is better suited to lightweight, low‑heat accessories.
- Sliding shelves:Sliding shelves allow rear access and servicing without removing equipment from the rack, useful for server maintenance. They are more costly and deeper; the 1U cantilever shelf is much cheaper and simpler for small items that don’t require rear access.
- Plastic or composite shelves:These are lightweight and sometimes cheaper but typically offer lower load capacity and less fire resistance. Steel powder‑coat shelves like ITM001147 are more durable and present a more professional finish.
- Zero‑U shelves or mounting brackets:Zero‑U solutions mount vertically in unused rack space, saving U height but often limiting accessibility. The 1U cantilever shelf balances accessibility and minimal footprint—useful where front access and a flat platform are required.
Customer feedback and representative comments
There are no official published customer reviews tied to ITM001147 in this product record. However, feedback commonly reported for similar 1U cantilever shelves from installers and IT managers tends to focus on a few recurring themes:
- Ease of installation:"Straightforward to fit with standard cage nuts—saved time during rack build."
- Practicality:"Perfect for keeping small power bricks and patching accessories tidy—doesn’t waste U space."
- Value:"A cost‑effective solution compared to sliding or vented options for lightweight kit."
These representative comments reflect the typical advantages customers cite when choosing a compact cantilever shelf. For verified, product‑specific testimonials, check retailer listings or request reference installations from the supplier.
Installation tips and safety considerations
- Confirm the exact maximum static load from the supplier (ITM001147) before placing heavy or safety‑critical equipment on the shelf.
- Use appropriate mounting hardware—many suppliers include cage nuts or basic fixings, but always verify what’s included and source additional fasteners if needed.
- Distribute weight evenly and avoid placing heavy concentrations to the shelf edge; secure items if the rack is in a mobile or high‑traffic area.
- Follow local regulatory and safety guidance (CE / UKCA compliance if required) and isolate powered equipment when performing installation or servicing.
