Entryway with articulating threshold
摘要:
An articulating threshold cap for use with a sill. The cap may include a substantially rigid body. The body can have a top wall, a first channel disposed below the top wall, the first channel configured to be engaged with a dam of the sill, and a second channel disposed below the top wall. The cap may also include a spring positioned below the top wall and at least partially within the second channel. The spring is configured to bias at least a portion of the top wall upward.
