Pro 5mm deep roller sponge adapter

The adapter that makes a difference in foam tyre truing with the Pro roller

When working with foam tyres in slot racing, preparation makes all the difference between a car that slides and one that grips cleanly. This adapter from the brand T800 —reference T870043— has been specifically designed for the Pro roller, offering a working depth of 5 mm that ensures a firm and play-free contact throughout the process.

Function and performance

The adapter acts as an interface between the Pro roller and the foam tyres, ensuring that they are perfectly centred and held during truing. The 5 mm depth is not a minor detail: it determines the active contact area and directly affects the uniformity of the tyre's surface finish. An unstable mounting transmits vibrations that result in irregularities that are difficult to correct later.

Its construction in high-strength T800 polymer maintains tolerances even during intensive work sessions, without deformations or play that compromise precision.

Compatibility and installation

This adapter is expressly developed for the T800 Pro roller model, so the fit is direct and intuitive. It requires no modifications or additional adjustments: it installs on the roller and is ready to use immediately.

If you already have the Pro roller on your workbench, this adapter expands its usability for 5 mm deep foam tyres, completing the preparation system.

Target audience

It is aimed at slot preparers who pay attention to every detail of the setup, whether in a club or during private sessions. Proper truing of foam tyres is one of the steps that most influences the car's behaviour in corners, and having the right adapter prevents the need to improvise with solutions that do not offer the same repeatability.

Frequently asked questions

Which roller is this adapter compatible with?

It is specifically designed for the T800 Pro roller. Its compatibility with other roller models from different brands or series is not confirmed.

What does the 5 mm depth mean in this context?

The 5 mm depth indicates the working dimension of the adapter, that is, the area where the foam tyre is housed during truing. This measurement must match the width or geometry of the foam tyre being prepared to ensure a correct fit.

Is this adapter necessary if I already have the Pro roller?

It depends on the type of foam you use. If you work with foam tyres that require a depth of 5 mm, this adapter is the specific complement for that case. T800 offers different adapters according to the required depth, so it is advisable to select the one that corresponds to your material.

Is its installation straightforward?

Yes. As an accessory designed to fit directly onto the Pro roller, the installation does not require additional tools or advanced technical knowledge. It can be installed and removed quickly on the workbench.
