Fusible Links

 6 |  7 |  8 |

Automatically close fire doors, windows, lids, dampers, vents, and more in the event of a fire. High temperatures melt the solder bond between links, causing them to separate and release their load. Install with S-hooks or chain (not included).
To ensure safety, replace links annually and do not paint or coat them. Use links in straight-pull applications only.
Style 1-5 links are for use on fire doors, windows, and lids.
Style 6 and 7 links are often used on fire doors, windows, hatches, dampers, and blowers.
Style 8 links are commonly used on fire doors, smoke and heat vents, and ducts.
Style 9 links are good for range hood applications.
Style 10 links are designed for use on dampers.
