HES 4501-1 Lip Extension for Electric Strikes
The HES 4501-1 lip extension is a precision accessory designed to extend the strike lip on compatible HES ASSA ABLOY electric strike systems. This component solves frame geometry challenges by adapting strike installations to non-standard, recessed, or retrofit conditions where standard lip depth is insufficient for reliable latch engagement.
Key Features
- Extends strike lip to accommodate non-standard frame depths
- Compatible with HES ASSA ABLOY electric strike systems
- Black finish for discrete integration
- Suitable for both retrofit and new construction applications
- Enables proper latch bolt engagement in recessed frame conditions
Technical Specifications
- Form Factor: Lip extension accessory
- Color: Black
- Compatibility: HES ASSA ABLOY electric strike systems
- Applications: Standard door frame installations requiring lip extension
Installation & Applications
The 4501-1 extension mounts directly to compatible HES electric strikes and is ideal for installations where frame geometry prevents the standard strike lip from achieving proper latch engagement. Common applications include retrofit projects on older door frames, installations with recessed or non-standard frame configurations, and new construction where frame depth variations require accommodation.
Note: Verify compatibility with your specific HES strike model before ordering. Installation should follow HES ASSA ABLOY guidelines to ensure secure mounting and reliable operation.
