The 2-piece guide rail FKS 145 is not only suitable for mains-powered circular handsaws, but also for battery-powered circular handsaws with a small base plate. The guide rail can be used with commercially available circular handsaws with a cutting depth of 40-70 mm, a saw blade diameter of 130-200 mm and a base plate with dimensions of min. 78 x 210 mm to max. 256 x 385 mm. 2 sponge rubber strips on the underside of the aluminium rail ensure non-slip contact with your workpiece and the two accompanying clamps with protective caps ensure that the rail is held firmly in place without damaging the surface. Straight and long cuts as well as mitre cuts through longer workpieces are effortless, even in areas far from the edge. The rubber lip reduces the risk of tears and also marks the cutting edge. Corresponding notches on the rail automatically open and close the protective cover of the portable circular saw when the saw is extended and retracted. The guide carriage is optimally adjusted to the rail using three adjusting screws. You can also quickly and easily align the portable circular saw on the guide carriage of the rail. The integrated alignment aid on the guide carriage helps you to set the correct distance between the saw blade and the guide rail - there is no need for a folding rule. The FKS 145 can be split in the centre and can be securely joined together using 2 connectors. With both parts together, you can achieve a cutting length of 110 cm - one part is sufficient for a cutting length of up to 55 cm. If you want to process extra-long workpieces, you can extend the guide rail with the optional extension set (Art. 6914000) to a cutting length of 220 cm - the ideal accessory for circular hand saws for cutting and shortening door leaves and kitchen worktops as well as for all work where guidance and safety are important to you.
