G-U Ferco SECURY Multipoint Locks with Latchbolts

G-U/Ferco SECURY Automatic Latchbolt Multipoint Locks for Enhanced Entry Door Security

The G-U/Ferco SECURY series represents one of the most advanced automatic multipoint locking systems available for residential and commercial entry doors. Unlike traditional multipoint locks that require manual engagement, SECURY locks feature latchbolts that automatically secure the door the instant it closes. This automatic latching technology eliminates the common problem of doors left unlocked and provides immediate security without any additional steps. MPLocks stocks the complete SECURY lineup, including options for standard 6 foot 8 inch doors and taller 8 foot applications, with backset configurations ranging from 55mm to 65mm to accommodate various door preparations.

Automatic Security with Three-Point Deadbolt Conversion

What sets the SECURY system apart is its dual-action security mechanism. When the door closes, the top and bottom latchbolts instantly extend approximately 20mm and lock in place to resist forced entry. A single 90-degree turn of the key or interior thumbturn then engages the central deadbolt while simultaneously converting all three latchbolts into a rigid deadbolt configuration. This creates a three-point deadbolt system that provides exceptional resistance against kick-ins, prying, and other forced entry attempts—all from one simple locking motion.

Stainless Steel Construction for Lasting Performance

Every SECURY lock in this collection features stainless steel construction with Ferguard coating for superior corrosion resistance. This makes them particularly well-suited for coastal environments, humid climates, or any application where long-term durability is essential. The three series available—35565 for standard lever handles, 35185 for grip handle applications, and 40526 for Euro profile cylinder operation—ensure compatibility with various handle configurations including smart locks, motorized systems, and minimalist pull bar designs.

Selecting the Right SECURY Lock Configuration

Choosing the correct SECURY lock requires matching your door height, backset measurement, and intended handle type. The 35565 series works with standard lever-type handles and positions the keyway above the lever—this is the most common configuration for residential entry doors. The 35185 series is designed specifically for grip handle applications where the handle provides the pulling force to close the door. For modern, handle-free installations using smart locks, motorized openers, or simple pull bars, the 40526 series operates entirely through the Euro profile cylinder without requiring lever handles.
