The 218528 is specifically designed for the Schüco Royal S aluminium system. You can identify it by the central hex-head grub screw and the distinctive double-ramp metal casting. If your window frame has a 15mm-16mm channel (Eurogroove) and your current keep looks identical to the image, this is the correct replacement part. Will replacing the locking keep help with my drafty Schüco window? Yes. Over time, the metal ramp on the locking keep can wear down, or the screw can loosen, preventing the window’s roller cam from pulling the sash tightly against the rubber seals. Replacing a worn 218528 keep often restores the compression needed to eliminate drafts and improve soundproofing. Do you I need a ‘handed’ keep if I have left or right-hand windows? No, this part is non-handed (universal). Due to its symmetrical design, it can be installed on either the left or right side of the window frame. You simply rotate the part 180 degrees to suit the orientation of your window opening. What should I do if my locking roller hits the keep instead of sliding over it? This usually means the keep needs a slight vertical adjustment. Because the 218528 keep is secured by a grub screw rather than fixed drill holes, you can loosen the screw and slide the keep up or down the frame by a few millimetres until the roller engages smoothly with the ramp. Does this replacement part come with fixings? Fixings are not typically included unless otherwise stated in the product description.
