GU Secury SH2 Multipoint Locks - Replacement Hardware

GU Secury SH2 Hook-Style Multipoint Locks with Anti-Slam Technology

The GU Secury SH2 series represents a specialized approach to multipoint door security, utilizing the distinctive Rhino Hook mechanism that GU Ferco developed for demanding residential and commercial applications. These locks integrate an anti-slam feature into the latch mechanism, a thoughtful design choice that requires the door to be fully closed before the hooks can extend. This prevents damage to door frames and eliminates the frustration of accidental lockouts that can occur with conventional hook locks. MPLocks stocks these locks in stainless steel construction with radius-end faceplates that don't extend the full door length, making them suitable for retrofit and new construction projects alike.

Rhino Hook Engagement for Superior Holding Power

The Rhino Hook design used in the Secury SH2 series provides exceptional security through its robust hookbolt projection of 15/16 inches (24mm). Unlike simpler locking mechanisms, these hooks engage automatically when the handle is lifted after door closure, creating multiple secure anchor points along the door edge. This lift-to-lock operation is intuitive for users while delivering the kind of forced-entry resistance that modern security standards demand. The two-hook configuration on standard models distributes holding force across the door height, reducing stress on any single locking point.

Flexible Backset Options for Various Door Profiles

Understanding that door constructions vary significantly, the Secury SH2 locks come in three backset configurations: 1-3/4 inch (45mm), 2 inch (50mm), and 2-3/8 inch (60mm). This range accommodates everything from narrow-stile aluminum doors to thick wood entry doors. The 92mm PZ (cylinder center distance) is standard across the line, ensuring compatibility with common Euro-profile cylinder handlesets. When measuring for replacement, always verify your existing backset from the door edge to the center of the keyhole before ordering.

Door Height Considerations and Extensions

Standard Secury SH2 locks are engineered for doors up to 8 feet in height, which covers the majority of residential and light commercial applications. For doors exceeding this height, GU Ferco offers dedicated Rhino Hook extensions that add an additional locking point near the top of the door. These extensions maintain the same stainless steel construction and hook projection as the main lock, ensuring consistent performance throughout. When ordering for oversized doors, measure the full door height and confirm whether an extension will be needed to achieve proper security coverage.
