🔧 FITMENT INFORMATION

To ensure a secure and stable fit, the extension legs are intentionally designed with tight tolerances.

As the parts are freshly printed, the fit may initially feel snug — particularly with the 3cm option due to the shorter overall length.

Once installed, this helps prevent unwanted movement or wobble during use. In some cases, a gentle twisting motion or basic tools may be required to remove the legs if needed.

⚠ IMPORTANT INFORMATION

Dimensions shown in this listing INCLUDE the original black rubber feet supplied with the skimmer.

The original black rubber feet are NOT included with this listing and WILL NOT be supplied.

You are purchasing the RED extension legs only.
