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.

Styles 1-5—Styles 1-5 links are for use on fire doors, windows, and lids.

Styles 6 and 7—Styles 6 and 7 links are often used on fire doors, windows, hatches, dampers, and blowers.

Style 8—Style 8 links are commonly used on fire doors, smoke and heat vents, and ducts.

Style 9—Style 9 links are good for range hood applications.

Style 10—Style 10 links are designed for use on dampers.

Parts Washers for Solvent-Based Solutions


Style A	Style B	Style C

Use these washers with solvent-based cleaning solutions that have a flash point above 105° F. Turn on the pump, and solution will flow to the flexible metal spigot. A fusible link closes the cover in the event of a fire.

Note: Do not use with flammable liquids.

Agitating Cleaner—Washers that agitate move the cleaning solution around in the tub to loosen dirt as the parts soak. They also have a neoprene hose with pistol-grip nozzle that adjusts the solvent flow from a light spray to a solid stream.

Filter—Washers with filter remove large particles to keep the solution cleaner longer.

Fusible Link Wire

Often found in older vehicles, this fusible link wire protects a circuit in applications where you can’t use a standard fuse. The conductor in the fusible link melts if there’s a short circuit or voltage spike, breaking the circuit to protect the rest of your wiring. Since the conductor needs to be thin enough to melt before the rest of your wiring overheats, choose a fusible link wire that’s four gauge sizes smaller than your circuit. If you’re replacing a fusible link that has burned out, make sure the new wire is the same length and gauge as the old one.
