How to install aluminum alloy window

Aluminum alloy windows should be installed indoors first, and then installed outdoors.

When assembling a single piece, install it first, aim at the top, and then aim at the chute below.

It can be seen that there are three holes at the bottom of the two vertical frames of the window sash, and the bottom is a half hole, which corresponds to the position of the pulley in the window sash. Pay attention to the feeling that the pulley should be placed on the chute

Sometimes the pulley will protrude and block the chute, so the installation is not good. At this time, use a Phillips screwdriver. In the hole between the three holes, there is an adjusting screw. When rotating counterclockwise, the height of the pulley will decrease and it can be put in.

After all installation, if the pulley is moved, the height of the pulley should be readjusted to meet the requirements of smooth sliding, no severe friction and good locking after the two window sashes are closed.
