We aren’t handy folks, so anything involving a drill is not our friend. The directions are all pictures, no words, no drill bit sizes for anchor holes. Suffice it to say just study the diagrams carefully before starting and know where you’re going! IE, rounded screws are for hanging brackets, flathead for pull cord mechanism. We’re impressed with finished product, clever design that gives several options for light. From afar you might think they’re plantation shutters. Overall happy.  One pull cord doesn’t move freely, but no incentive to take down and return.
