G-U Ferco Lock Cylinders & Tailpieces

Replacement Cylinders and Tailpieces for G-U and Ferco Multipoint Locks

G-U and Ferco multipoint locks are widely used in residential and commercial entry doors, and their cylinder and tailpiece components are essential for secure, reliable operation. When these parts wear out or need replacement due to rekeying or damage, finding the correct specifications is crucial. MPLocks stocks cylinders and tailpieces specifically designed for G-U and Ferco lock systems, including options compatible with Pella and Peachtree doors that utilize similar hardware. Whether you need to replace a worn cylinder, customize a tailpiece length for your door thickness, or convert to a thumb-turn only configuration, these components ensure your multipoint lock functions as intended.

American-Style Cylinders with Schlage Keyways

The American-style cylinders in this collection feature Schlage 5-pin SC1 keyways, making them compatible with one of the most common residential key systems in the United States. These cylinders are fully rekeyable, so locksmiths and homeowners can match them to existing keys or create new key sets. Available in finishes including bronze, brass, and satin chrome, these cylinders fit door thicknesses of 1-3/4 inch and 2-1/4 inch. When ordering multiple cylinders, they ship keyed alike for single-key convenience across all entry points.

Tailpieces for Custom Door Applications

Tailpieces transfer the turning motion from your key or thumb turn to the lock mechanism inside your door. This collection includes flat tailpieces with break-away score marks, allowing you to adjust the length in 1/8 inch increments to match your specific door thickness. Thumb-turn tailpieces in 48mm standard and 72mm extended lengths accommodate doors where keyed entry is not required, enabling the locking mechanism to operate solely from the interior thumb turn while maintaining full security functionality.

Selecting the Right Cylinder Length for Your Door

Measuring your door thickness before ordering is essential to ensure proper cylinder fit. Most standard entry doors are 1-3/4 inch thick, while some exterior doors measure 2-1/4 inch. Cylinders that are too long will protrude awkwardly and may not engage properly, while those too short won't reach the lock mechanism. For doors that fall between standard sizes, choose a cylinder designed for the thicker measurement and use the break-away tailpiece feature to trim it to your exact door thickness.
