View full detailsG-U (Gretsch-Unitas) and Ferco multipoint locks are widely used in residential and commercial entry doors across North America. Over time, specific components like cylinders, knob tails, and snap rings may wear out or require adjustment for different door thicknesses. MPLocks carries the individual accessories needed to service these systems, allowing you to address specific issues without the cost of full hardware replacement. From American-style cylinders with Schlage SC1 keyways to gripset conversion kits for thicker doors, these parts are engineered to integrate seamlessly with existing G-U and Ferco lock assemblies.
The G-U American cylinders in this collection feature flat tailpieces and use the popular Schlage 5-pin SC1 keyway, one of the most common residential standards in North America. This makes them easy to integrate with existing key systems or rekey through any local locksmith. Available in chrome and satin brass finishes, these cylinders include two keys and offer a straightforward replacement solution when your original cylinder is worn, damaged, or needs to match a new key system throughout your property.
Standard G-U hardware typically ships configured for 1-3/4 inch thick doors, but many entry doors measure 2-1/4 inches or even 2-3/4 inches thick. The gripset conversion kits in this collection provide all necessary components—including actuator cylinders, extended screws, and tailpieces—to properly install G-U handles on thicker doors. These kits are non-handed, working for both left and right configurations without modification, ensuring a secure and functional installation regardless of your door's swing direction.
When ordering G-U / Ferco accessories, accurate measurements are essential. For cylinders, confirm whether your system uses an American-style cylinder with a flat tailpiece or a Euro-profile cylinder—these are not interchangeable. For conversion kits, measure your door thickness precisely, as kits are designed for specific thicknesses like 2-1/4 inch or 2-3/4 inch doors. Knob tail replacement kits require knowing your exact door thickness and confirming you have the newer-style handle sets, as older models use a different configuration.
