Right Hand 400B Cambridge Multipoint Lock Trim – Active Handleset

Active Handleset 400B Right Hand – Cambridge Multipoint Lock Trim

The Amesbury® 400B Series Active Keyed Handleset is designed for the primary active door equipped with a multipoint locking system. This lock trim is a direct replacement for several popular multipoint handlesets, including the Integrity by Marvin Cambridge® series, Milgard®, G-U / Ferco®, and other American-style multipoint locks. It is suitable for exterior doors where secure key access and robust inside locking with a thumb turn are required.

The curved lever design pairs with a rounded, radius-top escutcheon plate, providing an updated look while maintaining compatibility with a broad range of doors. The handleset features a spring-loaded cassette for smoother lever action and comfortable everyday use.

Careful consideration was given to fitment, with a 1-3/4" (44.5mm) door thickness, 1.80" x 9.52" (45.7mm x 242mm) escutcheon plate, and 7.87" (200mm) screw hole spacing. The set utilizes a 5/16" (8mm) square spindle and offers a standard keyed cylinder (Schlage 5 pin, SC1 keyway) with an option for composite Kwikset® or Weiser® keyways. The unit is right-hand oriented, but lever handles can be removed and reattached if necessary. No set screws are used; instead, a snap ring system secures the handles to the escutcheon.

The hardware’s PVD Satin Nickel (US15) and Oil Rubbed Bronze finishes provide durability and style, with a solid brass base material offering superior corrosion resistance for exterior use.
