Middle Atlantic L5 Sloped PNL 23 - L5-SPNL-23

Middle Atlantic L5-SPNL-23 Sloped Presenter Panel Without Cutout

Overview

The Middle Atlantic L5-SPNL-23 is a sloped presenter panel designed for integration into Middle Atlantic L5-series lecterns. Supplied without any pre-cut openings, this blank panel gives integrators a clean, finished surface to work from — cut your own openings to spec rather than adapting around a factory cutout that doesn't match your exact AV component layout. For conference rooms, training centers, and presentation suites where the lectern surface needs to look purpose-built rather than patched together, the L5-SPNL-23 (often searched as L5 SPNL 23) is the starting point before you route, drill, or punch to suit your specific input panel, cable cubby, or device tray requirements.

Middle Atlantic has been the standard reference for rack and AV furniture integration in commercial installs for decades. This panel is part of that Middle Atlantic AV furniture and rack accessories ecosystem — sized and finished to drop into the L5 lectern frame without modification, gap-free.

Key Features

• Blank Panel Surface (No Cutout): Ships with zero pre-cut openings, which matters when your AV layout doesn't conform to a standard punch pattern. You define the cutout geometry — one large opening for a modular insert frame, multiple small ports for HDMI/USB/power, or a combination. No factory cutout means no compromises on placement or spacing.
• Width — 16.37 in (41.6 cm): Spans the full-width insert zone of the L5 lectern, giving you the maximum usable surface area for your panel layout. At just over 16 inches wide, there's enough horizontal run to fit a full modular plate row or a side-by-side arrangement of two smaller inserts without crowding.
• Height — 10.88 in (27.6 cm): Nearly 11 inches of vertical face on a sloped presenter surface is substantial — enough vertical space to stack two rows of modular inserts or accommodate taller device bezels. On a sloped panel, this height also translates to a comfortable presenter viewing angle for controls mounted at the top of the opening.
• Depth — 0.75 in (1.9 cm): At three-quarter inch depth, the panel itself stays thin and doesn't eat into the under-surface clearance inside the lectern cabinet. That matters when you're trying to fit a cable cubby, power strip, or equipment tray in the space immediately behind the panel.
• Sloped Presenter Orientation: The angled face positions your AV inputs toward the presenter rather than straight up or vertical — ergonomically correct for a standing presenter who needs to plug in a laptop, glance at a confidence monitor control, or reach a mic input without bending over the lectern.
• L5 Series System Fit: Designed as a direct fit component within the AV lectern and furniture accessories category. Swapping panels within an L5 lectern is a tool-accessible change, not a cabinet rebuild — you can reconfigure the presenter surface between installs or repurpose a lectern for a different room without ordering a new unit.

Integration and Compatibility

The L5-SPNL-23 is engineered as a component within the Middle Atlantic L5 lectern system. If you are specifying a complete presenter station, pair this panel with the appropriate L5 lectern base and any modular AV input frames or cable management accessories from the same family. The blank surface accommodates custom cutwork for standard modular AV plate systems — consult your AV contractor or systems integrator for cutout templates compatible with your chosen input modules.

For integrators outfitting multiple rooms with identical presenter stations, the blank panel approach is efficient: a single cutout template cut once and applied across all units keeps installs consistent. It also makes the lectern adaptable over time — as input standards change (DisplayPort replacing HDMI, USB-C superseding USB-A), the panel can be replaced or recut rather than replacing the entire lectern.

This panel is relevant to AV integration projects across corporate conference centers, higher education lecture halls, government briefing rooms, and houses of worship — anywhere a rack and AV furniture solution needs a finished, professional presenter surface. Pair with appropriate cable management solutions behind the panel to keep the lectern interior organized after cutouts are made.

Frequently Asked Questions

Q: Does the L5-SPNL-23 come with any pre-cut openings?

A: No. The L5-SPNL-23 ships as a blank sloped panel with no factory cutouts. Integrators cut their own openings to match the specific AV components and input modules being installed.

Q: What are the exact dimensions of the L5-SPNL-23?

A: Width is 16.37 in (41.6 cm), height is 10.88 in (27.6 cm), and depth is 0.75 in (1.9 cm).

Q: Is the L5-SPNL-23 compatible with other Middle Atlantic lectern models besides the L5?

A: The L5-SPNL-23 is designed for the Middle Atlantic L5 lectern series. Compatibility with other Middle Atlantic lectern lines is not confirmed in the available product documentation — verify fitment against the specific lectern model before ordering.

Q: Can the L5-SPNL-23 be used as a vertical panel rather than sloped?

A: The L5-SPNL-23 is designed as a sloped presenter panel for the L5 lectern system. It is not specified for vertical rack or wall-mount applications.

Q: What is the UPC for the L5-SPNL-23?

A: The UPC for the Middle Atlantic L5-SPNL-23 is 656747211041.

The L5-SPNL-23 is one of those components that looks deceptively simple on a spec sheet — 16.37 inches wide, 10.88 inches tall, three-quarter inch deep, no cutout — but it's the right call for integrators who refuse to let a factory punch pattern dictate their AV layout. I reach for the blank panel version specifically when the end user has a non-standard combination of inputs: say, a USB-C pass-through alongside a legacy VGA port and a recessed cable cubby. You can't buy that as a pre-cut, but you can build it in about 20 minutes with the L5-SPNL-23 as your canvas.

Technical Highlights:

• 16.37 in (41.6 cm) Width: Full-width coverage of the L5 lectern insert zone — no visible gaps at the edges, and enough horizontal run to fit a standard modular plate row or a side-by-side dual-module arrangement without crowding bezels together.
• 10.88 in (27.6 cm) Height: Close to 11 inches of sloped face gives you the vertical real estate for two stacked insert rows or a single tall device bezel, and the slope keeps the top of the panel at a natural glance angle for a standing presenter.
• 0.75 in (1.9 cm) Depth: Thin enough that behind-panel clearance stays usable — you're not sacrificing cable cubby or power strip space to the panel thickness itself, which becomes relevant once you start routing HDMI and power cables behind the cutouts.

Deployment Considerations:

• Cut your openings before installing the panel in the lectern — working on a flat bench with a jig or template is far easier than cutting in place, and the 0.75 in depth gives just enough material for clean router or jigsaw work without flexing.
• The blank surface means zero factory-tested fitment for specific AV module brands — confirm your chosen modular insert frame's outer bezel dimensions fit within the 16.37 × 10.88 in face before committing to a cutout pattern.

This panel is the right spec for higher education lecture halls and corporate conference centers doing a fleet deployment of identical presenter stations — cut one template, replicate across every unit, and the result is a consistent, purpose-built look that a pre-cut panel rarely delivers.
