Wago 221-412
Couldn't load pickup availability
The WAGO 221-412 2-conductor COMPACT splicing connector is the small reusable lever connector for clean printer wiring: two side-entry ports, transparent inspection housing, orange operating levers, and WAGO’s verified 0.14–4 mm² / 24–12 AWG conductor range for solid, stranded, and fine-stranded copper.
Why this over a twist connector
- Lever-actuated, no tool required. Strip 11 mm / 0.43 in, lift the lever, insert the conductor, and snap it closed. It is faster to service than a twist cap or one-time crimp when you are debugging a harness.
- Two wires, one potential. Use the 221-412 for simple in-line splices, one-in/one-out extensions, PSU lead joins, enclosure lighting runs, and compact Voron/Klipper wiring drops.
- Transparent body with test access. You can visually confirm insertion depth and probe the connection without taking the junction apart.
- Right-sized 221 family. Need more ports? The 3-conductor WAGO 221-413 and 5-conductor WAGO 221-415 are the same 221-series lever-nut format in sibling layouts.

Use it for
- Voron, V0, Trident, V2, and other Klipper printer wiring where you need a serviceable two-wire junction.
- Low-voltage accessory wiring and properly enclosed mains-side printer wiring installed by someone qualified for the circuit.
- Mixed solid, stranded, or fine-stranded copper wire runs where a reusable clamp is cleaner than a permanent splice.
Gotchas
- Not for aluminum conductors, damaged wire, or loose/open-air mains wiring. Use proper enclosures, strain relief, fusing, and local electrical-code practice.
- This is the 2-conductor 221-412. It is not the 3-port 221-413, the 5-port 221-415, or the larger 6 mm² 221-61x series.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
