The extension set allows you to quickly and easily extend your FKS 145 guide rail so that you can also safely cut large workpieces with the portable circular saw. The set extends the guide rail to 255 cm and enables a maximum cutting length of 220 cm. Two rail connectors ensure a quick connection to the existing guide rail. For even greater cutting lengths, you can combine the set with additional extension elements. Thanks to the high-quality aluminium design, you benefit from a long service life. Please observe the operating and safety instructions.
