NANO BLANK Panel 2HP Modular System

Eurorack Blank Panel for Clean, Closed Modular Racks

The NANO Modules 2HP Blank Panel is a slim Eurorack filler plate designed to occupy any unused 2 HP slot in a modular synthesizer case. Built in Spain, it keeps the front of a rack visually consistent while shielding the case interior from dust and accidental contact with internal wiring. This 2HP blank is the right choice for modular players who want a tidy, finished look without leaving gaps in a populated rack.

Knurled-Screw Mounting and a Range of Matching Sizes

Each panel ships with two M3 knurled (thumb) screws, so installation and removal can be done by hand — no tools required. Part of a broader NANO Modules accessory family that includes matching 4HP, 6HP, 8HP, 12HP, 16HP, and 20HP blank panels, this 2HP blank lets builders mix and match widths to fill any combination of leftover rows.

2 HP Width — The Narrowest Standard Eurorack Slot

Width matters in Eurorack because every module is measured in HP (Horizontal Pitch), where 1 HP equals 5.08 mm. A 2 HP panel is the smallest filler size available and is the right tool for closing the narrow gaps that appear when modules of different widths are rearranged. Built to the standard 3U Eurorack height, the panel lines up vertically with any module mounted in the same row.

• Width: 2 HP (10.16 mm) — closes the narrowest leftover slot in any Eurorack row.
• Format — 3U Eurorack height matches the standard used by Doepfer, Make Noise, Intellijel, and most other manufacturers.
• Two M3 threaded holes on the standard Eurorack pitch — aligns with the rails of typical cases.

M3 Knurled Screws — Tool-Free Installation

Mounting hardware is included in the box, so the panel is ready to install straight out of the package. Knurled screws can be tightened by hand, which is helpful when modules need to be swapped frequently during sound design sessions or live performance. The M3 thread is the standard Eurorack specification.

• Included Hardware: 2 × M3 knurled screws — hand-tightenable, no screwdriver needed.
• Thread Standard — M3 (3 mm), the same thread used by virtually all Eurorack modules and cases.
• No bus cable included — a blank panel carries no electrical connection.

Eurorack Compatibility and Spanish Manufacturing

Because the panel follows the universal Eurorack mechanical standard, it fits any case that accepts 3U modules — from a compact skiff to a multi-row performance case. NANO Modules is a Spanish electronics company based in Valencia.

• Compatible With: Eurorack modular synthesizer cases — fits any 3U row that follows the Doepfer/A-100 specification.
• Type: Eurorack Blind Panel — a passive filler plate with no electronic function.
• Made in Spain by Industrias Electrónicas NANO S.L., based in Valencia.

For Modular Builders Who Want a Clean, Finished Rack

This 2HP blank is the right choice for Eurorack players who need to close narrow leftover slots after rearranging modules or expanding a case. It suits studio owners who want a tidy, professional front panel without exposed rails, as well as live performers who rearrange their rack between sets and need a fast, tool-free way to fill gaps. Beginners building their first case will find it useful for closing empty rows before adding more modules.
