How to Install a Pulley System for Outdoor Curtains

Attach a double side-by-side pulley to the outside of one corner post. One-third of the pulley body should overhang the outside back corner of the post. Place the pulleys 1 inch above curtain height. Use the bracket and fasteners provided with the pulleys to attach them to the post.

Attach a second double side-by-side pulley of the same size beneath the first so that the pulley wheels of the bottom set touch the underside of the top set. Repeat your pulley attachment on the post on the opposite side of the curtain span.

Screw a medium-sized screw eye 4 inches below the pulleys on the outside center of the same post to which the pulleys are attached. Attach a tension pulley 6 inches off the ground, centered on the same side as the screw eye. Repeat for the second post.

Thread curtain cord up over the top outside pulley, across to the top outside pulley of the second post. Take the cord around and between the top and bottom outside pulley and back across and between the top and bottom outside pulley on the first post. Thread the cord downward through the screw eye. Take the cord through the tension pulley and back up through the screw eye to the top outside pulley. Pull the cord tight and tie a knot 2 inches beyond the top outside pulley.

Thread curtain cord up over the top inside pulley on the opposite post. Take the cord across to the top inside pulley of the first post. Take the cord around and between the top and bottom inside pulley and back across and between the top and bottom inside pulley on the second post. Thread the cord downward through the screw eye. Take the cord through the tension pulley and back up through the screw eye to the top inside pulley. Pull the cord tight and tie a knot 2 inches beyond the top inside pulley.

Attach the leading edge of each curtain to the knot.
