The AB441 is a Low Dome Stop, a solid cast‑metal floor stop designed for doors without thresholds (non‑undercut). Its low‑profile dome and durable rubber bumper prevent doors from over‑swinging while maintaining a clean, unobtrusive look. The AB441EXP version of the AB441 adds an Exterior Pack of stainless‑steel plated screws, providing a corrosion‑resistant mounting option ideal for more demanding environments. Functionally identical to the standard AB441, it includes upgraded fasteners for added durability. “T” variants typically denote Torx security fasteners. In this family, Torx fasteners are available for AB441 units, providing tamper‑resistant installation when higher security is required.
