Elsie Manufacturing B165-LONG HOOK Fusible Link
The Elsie Manufacturing B165-LONG HOOK Fusible Link is a critical thermal release mechanism designed for integration into fire dampers, ceiling radiation dampers, and overhead fire door assemblies. Engineered with a precision-calibrated 165°F temperature rating, this UL Listed fusible link utilizes a specialized bismuth alloy solder that melts at its designated set point, allowing the spring-loaded damper blades or doors to snap shut and prevent the spread of flames through HVAC ductwork. This Model B fusible link features a long hook design, facilitating a secure and versatile connection for contractors during fire damper replacement or new system installations. With a 1.5-inch length and 0.563-inch width, this component provides a 0.938-inch center-to-center distance, ensuring compatibility with standard curtains and multi-blade damper linkages. Built to handle load capacities between 1 and 10 pounds, these links are essential for maintaining NFPA 80 compliance and ensuring the integrity of fire-rated partitions in commercial and industrial mechanical systems.
Key Benefits- UL Listed and FM Approved: Meets rigorous safety standards for 165°F fire protection applications in residential and commercial settings.
- Long Hook Configuration: Provides extended reach for easier attachment to curtain style fire dampers and various mechanical release triggers.
- Precision Thermal Response: Features a reliable eutectic alloy solder that triggers rapid separation once the 165-degree threshold is reached.
- Corrosion-Resistant Construction: Durable stamping designed to withstand the ambient conditions found in HVAC ventilation systems.
- Universal Compatibility: Standard dimensions allow for seamless fusible link replacement across multiple damper brands and models.
What is the difference between a long hook and a short hook fusible link?
The long hook version, such as the B165-LONG HOOK, offers more clearance and flexibility for specific damper linkages where a standard short hook may not reach or secure properly. Always verify the hook length required by the original equipment manufacturer (OEM) to ensure proper tension and closure.
How often should HVAC fusible links be replaced?
Per NFPA 80 and 105 standards, fire dampers should be tested and inspected one year after installation and every four years thereafter (six years for hospitals). If a fusible link shows signs of corrosion, paint buildup, or physical damage during these inspections, it must be replaced immediately to ensure the life safety system remains functional.
Can I use this link for an application heavier than 10 lbs?
No. The Model B Fusible Link is strictly rated for a maximum linear load of 10 lbs. Exceeding this limit can cause premature mechanical failure or prevent the link from separating correctly at the 165F melting point. For heavier loads, a higher-rated link must be sourced.
