NANO BLANK Panel 20HP Modular System

Eurorack Blank Panel 20HP — Clean Rack Space Management for Modular Synthesizers

The NANO Modules BLANK Panel 20HP is a purpose-built Eurorack blind panel that fills empty rack space in any standard modular synthesizer case. At 20 horizontal pitch units wide, this panel covers substantial gaps left when modules are removed, swapped, or when a case is being populated gradually. The minimalist, Lissajous-inspired design keeps the rack looking tidy and professional while protecting the internal bus board and wiring from dust and accidental contact. The NANO Modules 20HP Blank Panel is the right choice for Eurorack builders who need to close out large empty sections of their rack without committing to a specific module.

Why the 20HP Blank Panel Stands Out

What makes this panel practical is the inclusion of two M3 knurled screws — the same thread standard used across the Eurorack ecosystem — so installation requires no additional hardware purchase. The knurled (textured) head allows finger-tightening without tools, which speeds up rack reconfiguration during studio sessions or live performance prep. As a passive, non-electrical accessory, the panel adds zero load to the case power supply and introduces no signal interference.

Rack Width — 20 HP Coverage for Larger Empty Sections

In Eurorack terminology, HP (Horizontal Pitch) is the standard unit for module width, with 1 HP equal to 5.08 mm. The 20 HP width of this panel makes it ideal for closing out the space left by a removed 20 HP module or for filling a wide gap in a partially populated case. This is the largest blank panel in the NANO Modules lineup, designed for builders working with substantial rack real estate.

• Width: 20 HP (101.6 mm) — covers the widest common Eurorack module footprint
• Height: 3U (128.5 mm) — standard Eurorack panel height

Mounting Hardware — M3 Knurled Screws Included

Eurorack panels mount to the case's threaded rails using M3 screws, the universal standard across Doepfer, Make Noise, Intellijel, and most other case manufacturers. This panel ships with two knurled M3 screws, so no separate hardware purchase is needed. The knurled head design enables hand-tightening, eliminating the need for a screwdriver during routine rack changes.

• Included Screws: 2 × M3 knurled screws — ready for immediate installation
• Screw Type: Knurled head for tool-free finger tightening

System Compatibility — Universal Eurorack Fit

As a passive mechanical accessory, the panel imposes no electrical requirements and works with any Eurorack-compatible case regardless of power supply type, bus board configuration, or row layout. It contains no bus cable and no active circuitry — it is a pure blank panel for physical rack management.

• System: Eurorack — fits all standard 3U Eurorack cases and rails
• Bus Cable: No — passive panel, no electrical connection
• Form Factor: Blank panel

Who Should Use the NANO Modules 20HP Blank Panel

The NANO Modules 20HP Blank Panel is the right choice for Eurorack builders who need to fill wide empty sections of their modular rack — whether during the gradual build-out of a new case, after removing a large module for repair or sale, or when designing a clean visual layout for performance. Studio producers who frequently swap modules will appreciate the tool-free M3 knurled screws that speed up reconfiguration. Case builders and DIY enthusiasts will find it useful for prototyping layouts before committing to specific modules. Beginners expanding their first rack benefit from a tidy, protected interior that prevents dust buildup on the bus board.

NANO Modules — Spanish Modular Engineering

NANO Modules is the brand of Industrias Electrónicas NANO S.L., a Spanish electronics manufacturer based in Valencia. The company specializes in Eurorack modular synthesizer accessories, including blank panels in multiple HP widths, bus boards, power adapters, and complete portable cases like the CAIXA 104. Their blank panel lineup covers 2, 4, 6, 8, 12, 16, and 20 HP sizes, giving builders a complete range of options for any rack configuration.
