Rooftop upblast exhaust fan being serviced
Exhaust Fan Hinges

The small upgrade that makes every cleaning better

Without hinges, cleaning behind an exhaust fan means lifting it off its curb, straining its wiring, and risking damage every single visit. A hinge kit lets the fan tip back safely, so the fan base and duct opening actually get cleaned.

What's Included

What a hinge kit changes

  • Fan tips back on a fixed hinge instead of being lifted loose
  • Hold-open retainer keeps the fan safely propped while the crew works
  • Wiring and flexible conduit protected from repeated strain
  • Fan base and duct opening fully accessible for cleaning
  • Curb and fan protected from drop damage
  • Installed once, used on every cleaning after
Why It Matters

Unhinged fans get half-cleaned

When a fan cannot be safely tipped, crews are forced to work around it, and the grease directly under the fan stays put.

Better cleaning, every visit

Full access to the fan base and duct opening means the dirtiest part of the system stops being skipped.

Protects your equipment

Repeated lifting damages wiring, curbs, and fan housings. Hinges end that.

Safety on the roof

A controlled tip-back is safer for anyone servicing the fan, in any weather, which in this part of the country means rain.

Pays for itself

One hinge kit prevents wiring repairs and fan damage across years of service visits.

Common Questions

Hinge kit questions

Does my fan need a hinge kit?

If your fan sits directly on its curb with no hinge, yes. We confirm during your estimate or next cleaning.

Is this required?

NFPA 96 requires exhaust fans to be serviceable with access for cleaning, and it calls for hinged upblast fans with flexible weatherproof cable. Hinge kits are the standard way to meet that.

Can it be installed during a regular cleaning visit?

Usually, yes. It is a natural add-on to a scheduled service.

Make every future cleaning count

Ask for a hinge kit on your next visit and the fan gets tipped back properly from then on.
