Fusible Link 165 Degree Dayton 2TGJ3 for Fire Dampers
Best for Daytons 2TFZ4 to 2TFZ9 dampers and similar units, this 165°F fusible link is UL Standard 33 listed. It fits multiple Dayton models and related damper assemblies, supporting quick replacements in systems that require precise shutdown at 165°F. This option is well suited for facilities with Dayton equipment and a need for a compact, reliable link that activates reliably under designated heat conditions.
Who it’s best for: maintenance crews with Dayton damper installations seeking a direct, compatible replacement. Why chosen: strong standard compliance and broad damper compatibility reduce downtime during replacement. Caution: confirm exact damper model fit before ordering to avoid mismatch with non-Dayton units.
Pro Chutes Trash Chute Fusible Link Kit 165°
This universal kit is designed for trash chute doors and laundry chute discharge doors. It features a 165°F activation temperature, UL listing, and NFPA compliance. The included 30-inch chain can be cut to size, accommodating horizontal or vertical installations. Best for sites with mixed chute configurations or where a single universal kit is preferable for multiple doors.
Who it’s best for: facilities with varied chute systems that require a flexible, adjustable solution. Why chosen: adjustable chain reduces inventory complexity. Caution: verify that chain length fits your specific chute door depth to ensure reliable activation.
165 Degree Fusible Link Dayton 2TGJ2 for Fire Dampers
Designed for multiple damper families, this 165°F link fits several Dayton models (2TGA through 2TGF series and related dampers). The length is 2-3/4″ with a 1″ width, making it a longer option for deeper damper installations. Best for systems with deeper damper housings or where longer fusible links are required to reach the actuator mechanism.
Who it’s best for: engineers working with deeper damper housings in commercial buildings. Why chosen: broad compatibility with common Dayton damper series. Caution: longer length means it may not suit compact installations without trimming or precise routing.
Fusible Link 165 Degree
This 165°F link focuses on laundry and trash chute discharges and compatible dampers from Dayton, Lloyd Industries, Ruskin, and others. The stable size is 1.626″ by 0.875″. This product is ideal for facilities with laundry/trash chute systems combined with fire damper doors needing dependable fusible linkage.
Who it’s best for: sites needing a compact, widely compatible fusible link for chute doors. Why chosen: broad compatibility reduces the need for multiple SKUs. Caution: size must match the specific chute door and damper assembly to ensure proper engagement at activation temperature.
Globe Fusible Links 165 Degrees Model B
This 165°F model from Globe lists a 2.36″ length with a 0.75″ width and a .125″ thickness. It also includes a bonus stainless steel S-hooks kit. Best for general 165°F needs with extra hardware for quick installation. Suitable for a range of dampers and discharge doors requiring a reliable fusible link.
Who it’s best for: facilities seeking an all-in-one package with hardware included. Why chosen: bonus hooks simplify mounting. Caution: verify load range and compatibility with your specific damper or door model to avoid fit issues.
Globe Fusible Links 360 Degree Model B
This 360°F model is intended for high-heat scenarios, with the same 2.36″ by 0.75″ profile and .125″ thickness. It offers a higher activation temperature for specialized applications while maintaining a compact footprint. Best for systems that require a higher-temperature safety link, or where 360°F activation is a design requirement.
Who it’s best for: facilities needing higher-temperature protection in specific zones. Why chosen: 360°F rating provides a different compliance path. Caution: not suitable where 165°F is mandated by local codes or equipment specifications.
Buying Guide: Key Considerations For Fusible Links And Fire Dampers
What determines the right fusible link? Activation temperature, damper compatibility, and physical size are primary. Most facilities use 165°F links for standard 3‑hour fire ratings, but some equipment may need higher or universal options. Always verify UL Standard 33 listing and NFPA compliance for code adherence.
Damper compatibility matters. Look for models that list damper families and manufacturers supported. If your system uses Daytons, Lloyd, Ruskin, or Globe components, prioritize those links explicitly designed for those assemblies to minimize installation issues.
Installation and sizing: measure the damper housing depth and the chain or link length needed. Packages that offer adjustable chains or easy trimming reduce waste and downtime. Consider whether extra hardware (like S-hooks) comes bundled, which simplifies on-site setup.
Safety and maintenance: choose UL-listed products and confirm whether you need to replace a single link or an entire kit when a damper is serviced. For shared chutes, universal kits can lower SKU count but may require precise trimming to fit.
FAQ
- What is a fusible link, and why is it used with fire dampers?
A fusible link is a heat-sensitive device that activates at a specified temperature to shut a fire damper, helping block smoke and flames. - What activation temperature is typical for these links?
Most options listed here activate at 165°F (74°C), with some specialized models offering higher ratings like 360°F. - How do I know which damper model I have?
Check the damper’s model number and manufacturer, then refer to the product’s listed compatible damper families to ensure correct fit. - Are these links UL listed and NFPA compliant?
Yes, all listed products in this guide reference UL Standard 33 listing or NFPA compliance where noted, ensuring code-aligned safety. - Can I use a universal fusible link kit for multiple doors?
Universal kits offer flexibility, but confirm that the chain length and link size fit each door type to avoid incorrect activation timing. - What installation pitfalls should I avoid?
Avoid mismatched lengths, improper mounting, or installing a link that cannot reach the damper actuator. Always trim or adjust as required for a secure fit.
