RS1U-SLIDER Universal Flat 1 Space Sliding Shelf - Rack-Ready Solution

In this review the RS1U-SLIDER Universal Flat 1 Space Sliding Shelf is evaluated for rack-based AVL and live sound setups where a compact, sturdy sliding shelf is required. The bottom line: this is a purpose-built 1U metal shelf for 19 in racks that delivers a simple, reliable platform for players and small electronics, but it must be mounted to both front and rear rack rails to prevent bending. Installers who need a shallow, sliding tray for consumer electronics will appreciate the fit and straightforward functionality.

Key Features

• Universal 19 in compatibility: Fits standard 19 in rack rails so it can hold CD/DVD players and similar components without modification.
• 1U profile: Saves vertical rack space while providing a flat sliding surface for shallow devices.
• Sliding action: The rail mechanism provides access to rear connections without removing equipment, helping with quick cable access and maintenance.
• Mounted on front and rear rails: Requires both front and rear rack rails for installation to avoid bending, ensuring long term rigidity when installed correctly.
• Compact footprint: At 16 in wide by 15 in deep the tray fits racks with depths from 15 in to 21 in, making it suitable for shallow cabinet installations.
• Metal tray construction: A metal shelf gives a stable platform for consumer electronics such as DVD players, VCRs and small AV gear.

Who It's For

The RS1U-SLIDER is aimed at audio-visual technicians, small live sound rigs, and studio operators who need a shallow, sliding shelf inside a 19 in rack to store CD/DVD players, VCRs or similar consumer electronics. It is particularly useful where rear cable access is needed and vertical space is limited.

It is not for those looking for an under-desk keyboard tray or a deep equipment shelf; it requires both front and rear rack rails for safe mounting, so installers without a rear rail or with nonstandard rack depths should look for an alternative that supports single-rail mounting or deeper units.

Pros & Cons

Pros

• Solid fit for 19 in rack equipment and a 1U profile that conserves rack space.
• Smooth, functional sliding action reported by many customers for easy rear access.
• Compact 15 in tray depth that fits racks with 15 in to 21 in depths, ideal for shallow cabinets.
• Metal construction provides a stable platform for consumer electronics.

Cons

• Must be mounted using both front and rear rack rails; failure to do so can lead to bending.
• Quality control on the slide mechanism and finish is mixed across user reports, so inspect before final installation.
