The Endura Z-Series ZAA3685FN Articulating Cap Door Sill features a durable all-aluminum construction with articulating cap technology designed to deliver superior weather sealing and long-lasting performance for exterior inswing doors.

The articulating cap pivots slightly when the door closes, allowing the door sweep to press against the cap and create a tight seal along the bottom of the door. This helps reduce drafts, prevent water infiltration, and block dust or debris from entering beneath the door.

Engineered for reliability and durability, this sill system is ideal for residential entry doors and French door systems requiring strong weather protection and consistent sealing performance.
