Quaker Multipoint Lock Hardware Replacement Parts

Replacement Multipoint Lock Hardware for Quaker Doors

Since 1949, Quaker Windows and Doors has built a reputation for quality craftsmanship in the fenestration industry. Over the years, Quaker has partnered with several trusted multipoint lock manufacturers, meaning replacement hardware depends on identifying which system your door uses. MPLocks carries compatible parts from all three brands found on Quaker doors—HOPPE, Amesbury, and Ashland—so you can restore full function to your entry or patio door without replacing the entire lock assembly.

Understanding Your Quaker Lock System

Quaker doors feature multipoint locks from three different manufacturers, each with distinct characteristics. HOPPE systems use European-style hardware with 7-7/8 inch or 8-1/2 inch screw spacing and require a Euro Profile cylinder positioned below the lever. Amesbury and Ashland systems are American-style locks using standard cylinders with flat tailpieces, but they differ in screw spacing—Amesbury matches HOPPE at 7-7/8 inch or 8-1/2 inch, while Ashland uses 7-1/4 inch spacing. Measuring your existing hardware is the first step to finding the right replacement.

Euro vs. American Cylinder Compatibility

The cylinder type determines which handlesets will work with your Quaker door. European-style HOPPE locks accept Euro Profile cylinders, which have a distinctive figure-eight shape and mount through the door edge. American-style Amesbury and Ashland systems use traditional cylinders with flat tailpieces that connect to the lock mechanism. Knowing which cylinder style your door requires ensures you order parts that integrate seamlessly with your existing multipoint lock.

Measuring Screw Spacing for Accurate Replacement

Screw spacing—the distance between the center of the top mounting screw and the center of the bottom mounting screw on your handleset—is critical for finding compatible replacement trim. Measure your existing handle plate carefully before ordering. HOPPE and Amesbury handlesets come in both 7-7/8 inch and 8-1/2 inch configurations, while Ashland uses a unique 7-1/4 inch spacing. Ordering the wrong screw spacing means the new handle won't align with your door's existing mounting holes.
