Product Features
Technical Overview
This rack shelf features a fixed surface depth of 27.56 inches (70cm) with adjustable front and rear mounting brackets that slide to fit rack depths between 19.5 and 38 inches. The 1U height (1.60 inches) and 17.50-inch width ensure compatibility with EIA-310-D standard 19-inch racks, while the vented design uses precisely spaced perforations to maximize passive cooling.
The shelf's load-bearing structure is built from SPCC cold-rolled steel, known for its strength and corrosion resistance in industrial applications. All mounting hardware—including M5 screws, cage nuts, flanged lock nuts, and truss head screws—is included for straightforward installation in threaded or unthreaded rack holes.
Key Product Advantages
The ADJSHELF combines adjustable mounting depth with robust construction to address common rack installation challenges. Its versatility eliminates the need for custom shelving when dealing with varying cabinet depths, while the vented surface actively supports thermal management for heat-generating equipment.

Deployment / Use Cases
This adjustable vented shelf is ideal for data centers, server rooms, network closets, broadcast studios, and AV racks where equipment depth varies or thermal management is a priority. It provides a stable platform for organizing hardware, tools, or accessories while maintaining airflow.
Common deployments include mounting 1U servers or network switches in mixed-depth racks, creating auxiliary storage for patch panels or small appliances, and supporting test equipment in lab environments. The shelf also works well for holding power strips, KVM switches, or cable management panels that benefit from vented surfaces.
Data Center & Server Room
Install servers, NAS devices, or UPS units in racks with non-standard depths. The adjustable brackets ensure secure mounting regardless of cabinet size, while venting aids in heat dissipation.
- Supports server hardware
- Adapts to various cabinet depths
- Promotes airflow in dense racks
Network & AV Infrastructure
Use for network switches, routers, patch panels, or AV receivers in equipment racks. The shelf adds organized storage without blocking ventilation, keeping gear cool and accessible.
- Holds networking equipment
- Fits AV racks
- Organizes cables and accessories
Physical Profile
