GU New Breed Panther Multipoint Locks with Tongues

GU Panther Tongue Multipoint Locks: Replacement Parts and Complete Kits

The GU NEW BREED Panther series represents G-U Ferco's streamlined approach to multipoint door security, utilizing locking tongues at three points along the door edge for dependable engagement with the frame. While G-U has discontinued the Panther tongue version, MPLocks maintains inventory of lock cases, installation hardware, and complete lock kits for those maintaining or repairing existing Panther installations. These locks feature the distinctive NEW BREED manual lift-handle-to-lock operation, where raising the lever engages all locking points simultaneously for a secure seal.

Precise Compatibility with 45mm Backset and 92mm PZ Spacing

Every GU Panther component in this collection is engineered with a standardized 1-3/4 inch (45mm) backset and 92mm PZ measurement, ensuring consistent compatibility across the NEW BREED platform. The lock cases and kits feature stainless steel construction with corrosion-resistant coatings, built to withstand years of daily use. The croppable design accommodates doors from 73 inches to 86-1/2 inches in height, with top extensions available separately for taller door applications.

Transitioning from Panther Tongues to Wolverine Shootbolts

For installations where Panther tongue components are no longer available or practical, the GU NEW BREED Wolverine series with shootbolts offers the most straightforward replacement path. Both systems share the same backset, PZ spacing, and key-above-handle orientation, making the transition seamless without requiring door modifications. The Wolverine shootbolt mechanism provides equivalent security while using more widely available components for future service needs.

Measuring and Selecting the Right Panther Lock Components

When ordering replacement parts for a GU Panther system, confirm your existing lock uses the key-above-handle configuration rather than the Europa series key-below-handle design, as these systems are not interchangeable despite similar appearances. Measure your current backset from the door edge to the center of the lever spindle hole—it should be exactly 1-3/4 inches for NEW BREED compatibility. For complete lock kit installations, measure your door height to determine whether the standard croppable kit or additional top extensions are required.
