How to install the background scroll of wedding photography

Buy some expansion screws of model 12, then hold the main box of the backstage shaft by hand and mark the position of the hole on the wall with a pen.

After marking, punch a hole in the blank of the main box position, then install the main box, and then hold the axis of the background with your hand to measure the position of the other side of the box. Here is a trick: the best position is that the main box is installed in place (the main box is dead), and half of the thin axis of the box is installed on the background axis.

Finally, install the manifold, then attach the background to the background shaft and install it on the main box and manifold, and screw the screws to be OK.

Before that, ask someone else to borrow an electric drill or spend tens of dollars to let others help you install it.
