Installation Steps for Window and Door Roller

The installation steps for window and door pulleys are as follows:

1. Preparation: before installing the door and window pulleys, make sure to clean the door and window frames and pulley grooves of debris and dust to ensure a smooth installation.

2. Check the pulley type: Select the appropriate type of pulley according to the type and weight of the door or window. Common pulley types include single and double pulleys, which need to be selected according to the actual situation.

3. Locate the pulley groove: Determine the location and number of pulleys to be installed, usually at least two pulleys need to be installed for a door or window. Ensure that the pulleys are at the right distance from the edge of the window or door and mark the installation position on the pulley grooves.

4. Pre-drill holes: Using an electric drill and a suitable drill bit, pre-drill holes at the marked locations on the pulley slots. The diameter of the drilled holes should match the diameter of the pulley screws.

5. Mounting the pulley: Align the pulley mount with the pre-drilled holes and secure the pulley with the screws. Make sure the screws are secure, but not over-tightened. In case of double pulleys, make sure the position of both pulleys is symmetrical and balanced.

6. Test and adjustment: After completing the installation of the pulleys, test the opening and closing of the doors and windows. If you find that the sliding is not smooth or there are abnormalities, you can adjust the position of the pulleys appropriately or check whether the installation is correct.

Please note that the above are general installation steps, the actual installation process may vary slightly depending on the type of door or window and the brand of the pulley. If you are confused or unsure about installing door or window pulleys, please consult a professional door or window installer or read the installation instructions for the pulleys.
