Shaker (square) sticking is one of the most popular door profiles today. The
clean lines and classic look fit a number of architectural styles from Craftsman
to Contemporary. In some environments, door professionals have been wary
of installing a door with shaker sticking in an exterior application for fear of
water pooling on the sticking surface. Simpson’s solution is shaker sticking,
with a gently sloped Waterfall™ profile.
This profile allows water to cascade off the sticking and away from the door.
And since the slope is moderate, it is hardly visible, resulting in a door that
looks as good as it performs.
