Please see the question below to be sure to not exceed a certain total length, depending on the kind of keyboard you have.

General : We recommend keeping the total length of your cable under 15 feet. If you go beyond, the cable can lose it initial transmission power.

In case you have a keyboard with a lot of LEDs, RGB or Drop CTRL, we recommend not going over 10 feet maximum and even 7 feet in some cases. Please, keep in mind if you choose a coil that it needs quite a lot of cable to be done so take this into account in your final calculation. Please see the question above for more informations.

Wooting Keyboards, if you multiple keys pressed when connecting your cable, we recommend to use ''RGB brightness soft limiter'' in the Wootility app.

1 feet ≈ 30cm

1 inch ≈ 2,54cm

We currently provide 2 different diameters for your coils :

3/8inch diameter (9,5mm)

1/2inch diameter (12,5mm)

You can compare both diameters here. Black coil on the left is 3/8 and both white in the middle and black on the right are 1/2.

Please not that those are internal diameters.

For sure! The coil is purely aesthetic. Although we reverse them, you should not pull the coil and play with it so please be careful guys. It might become loose and not as perfect as day one.

That's totally up to you and your preferences. Usually, people tend to choose the colors according to their desk set-up, or their new keycaps.

You can have a look at our color chart here!

If you have no inspiration or if you want any advice, do not hesitate to drop us an email or contact us here. We would be glad to help you!

Also, you can find some great inspirations on our pre designed cable collection and on our Instagram, this should help you a lot!

Techflex is a really good way to assure a good looking coil and keep it tight durably.

In case you do not want to add any color to the paracord you chose, you can go for a clear techflex which will not add any color and will only assure your cable to be neat and durable.

Lemo-like connectors are high-end detachable connectors that fits official Lemo® detachable connectors. They are push-pull connectors so they are easier to plug than GX16 aviators.

They come with some super nice and luxurious colors as Copper, Gold, Blue, Black and Silver. They are visually the same as official Lemo®. Their only difference is their price, almost twice cheaper than an official one.
