The SkyLift saddle attaches to the riser with the supplied nut and bolt. The SkyLift saddle fastens to the roof beam using the supplied lag screws. An interesting SkyLift design is that the holes on one side of the saddle are off-set from the other side, which prevents the lag screws from colliding in the middle. After setting the remainder of the rafters on the 24-in. layout, we made 24-in. layout marks down the two outside rafters and snapped chalk lines to set the 2x2 purlins, which run on top of and perpendicular to the rafters. We nailed corrugated molding on top of the 2x2s, watching the peaks and valleys at the rafters to make sure they were lined up.
We pre-painted all of the framing lumber with primer and two top coats before we installed it on this project. Be sure to paint the end grain as well, which helps to protect the wood from moisture.
