The video shows a step-by-step guide on how to fit the bottom sash on a PVCu sliding sash window. First, lift the bottom sash into position and then fix it to the brackets as shown. Now, insert the tilt arms into the canal found on the sides of the sash. You do this by simply sliding them into place. Push the sash into its upright position and fix the sash to the brackets found at the bottom by screwing in another set of screws on both sides. The sash should now be fixed to the brackets using a total of 3 screws on each side.
