Modular DIN Rail Mount for 2–10 Keystone Jacks

This modular system includes DIN-rail-mountable holders for 2, 4, 6, 8 and 10 standard Keystone jacks, such as RJ45, coaxial, optical, and audio modules.
Each holder is designed to fit perfectly onto a standard 35 mm DIN rail (EN 60715) and aligns with standard DIN module widths for a clean, professional finish in enclosures, server racks, and home automation panels.

✨ Features:
✅ Available in 4 versions:

2 keystone jacks → 1 DIN (17.5 mm)

4 keystone jacks → 2 DIN (35 mm)

6 keystone jacks → 3 DIN (52.5 mm)

8 keystone jacks → 4 DIN (70 mm)

10 keystone jacks → 5 DIN (87,5 mm)

🛠️ All versions snap securely to 35 mm DIN rails using integrated clip tabs and a rear locking pin – just like standard circuit breakers.

🔩 Modules are inserted manually and secured with a screw-on front cover using 3 × M2 × 4 mm to 10 mm countersunk screws (not included).

➕ Versions with more than 2 ports include integrated separators between jack slots to ensure spacing and alignment.

🧰 Assembly Instructions:
Insert Keystone jacks into the holder

Attach the front cover using 3 × M2 countersunk screws (maximum 10 mm length)

Insert the printed rear locking pin

Snap the module onto a standard 35 mm DIN rail

Route and connect cables as needed

⚠️ Use countersunk screws for flush fitting with the front cover
⚠️ Supports recommended under the locking pin slot for optimal print quality
🖨️ Optimized for FDM 3D printing – layer height 0.2 mm or finer recommended

🧪 Recommended Materials:
💪 PETG or ABS – for durability and resistance to heat and flex

🧵 PLA – suitable for indoor or light-duty use

🎯 Perfect for:
DIY network cabinets, structured cabling upgrades, smart home systems, patch panels, or anyone needing clean DIN-rail integration of keystone modules.

🎉 Print only what you need. Mount. Snap. Connect. Done!

Printer type:
🖨️ FDM / Cartesian or CoreXY / Bowden or Direct drive
