There are several ways in which you can hang a rope swing on a swing beam. Here are the two primary ways we recommend:
Method A
Use a swing hanger with a large enough loop for the rope and attach the rope to the hanger with a load-bearing knot such as a bowline knot.
Method B
Drill a hole in the swing beam, using a drill bit that is at least the same diameter as the rope. Next, feed the rope through the hole and secure with a knot on the top side of the beam. Using this method, you may want to use sandpaper to smooth the edge of the hole, or line it with some soft or smooth plastic, to prevent the rope from fraying.
