CB Race Copper Braid: precise electrical contact for your slot car

The braid is one of those components that makes the difference between a car that responds faithfully to the controller and one that hesitates during braking or loses power irregularly. This CB Race copper braid, with 0.25 mm thickness and 3.75 mm width, comes in a 1 metre length bag, allowing for the exact cut needed for each chassis without wasting material.

Features and function

• Material: high conductivity copper
• Thickness: 0.25 mm
• Width: 3.75 mm
• Length per bag: 1 metre
• Reference: SP104125

Copper is the classic material for slot braids due to its excellent electrical conductivity and flexibility. It allows the guide to move freely in the slot without generating mechanical resistance, which is especially valuable when working with demanding motors or in club competition where every millisecond counts.

Installation and preparation

Cut the necessary length according to the chassis and the type of guide used. A clean cut with scissors or a precision cutter is sufficient. It is advisable to remove any remnants of old braid, clean the guide contacts thoroughly, and ensure that the new braid is well seated and without forced bends that could generate false contacts.

The width of 3.75 mm makes it compatible with the vast majority of guides on the market. If you are working with narrower competition chassis, check the tolerances before installation.

Common mistakes

• Leaving the braid too long: this generates unnecessary friction and can affect the guide's response.
• Tightening it excessively when securing: this reduces its flexibility and shortens its lifespan.
• Not cleaning the contacts before the change: no matter how good the new braid is, a dirty contact will limit its performance.

Frequently asked questions

How many cars can I prepare with 1 metre of braid?

It depends on the chassis and the cut length you use, but with 1 metre it is common to prepare between 4 and 8 pairs of braids depending on each car's configuration.

Is it compatible with universal rail guides (Scalextric, Ninco) and Sport rail (Scaleauto, Slot.it)?

Yes. The width of 3.75 mm and the flexibility of the copper make it suitable for the most common guide types in both rail systems.

How often should braids be changed?

For recreational use, checking them every few sessions is sufficient. In competition, many preparers check them before each race or championship, as a poor contact can ruin a result.

Do I need any special tools to install them?

No. A pair of precision scissors or a cutter and some care in the installation is more than enough. Fine-tipped tweezers make the job easier in chassis with limited space.

The CB Race copper braid SP104125 is a 1-metre slot car braid strip measuring 0.25 mm thick and 3.75 mm wide, designed for precise electrical contact between the guide and the track rail. Essential for slot car tuning, club racing preparation, and achieving consistent throttle response. Compatible with most slot car guides for both universal rail and Sport rail systems.
