HOFFMAN

HOFFMAN F4490EIN 90° Elbow Inside Opening 4x4

SKU CH-2E9N-SZRR1

A 90-degree inside-opening elbow connects 4x4 wireway runs and meets CSA 22.2 No. 26, UL 870 and IEC 60529 standards

  • Directs cable runs at 90° inside the enclosure
  • NEMA Type 1 rating protects indoor wiring
  • Screw-clamp cover secures without extra hardware
  • 16-gauge steel construction resists impact and corrosion
  • CSA and UL listed for code-compliant installations

F44 Series 90° Inside Elbow

The Hoffman F4490EIN is a painted steel wireway fitting that turns a F44 series run ninety degrees while keeping the cover on the inside radius. It suits installers building NEMA Type 1 raceways in commercial or light-industrial electrical projects.

Thermals Noise and Power Draw

As a passive steel component the elbow generates no heat, emits no sound and draws no electrical power. Its 16 gauge painted finish resists corrosion in indoor environments without active cooling or energy consumption.

Inside Opening Cover Configuration

The cover mounts on the top and inside surfaces and locks with screw clamps, so the fitting only matches wireway runs that require an inside opening at the bend. Builders needing an outside opening or a different cover style must select another part.

Questions about this item

How is the Hoffman F4490EIN 90° elbow installed, and which step is often missed?

Align the 90-degree inside-opening elbow with the F44 series wireway, then secure the screw-on cover using the screw clamps on both the top and inside surfaces; the step often missed is tightening the inside clamps after the top ones.

What maintenance or replacement will the elbow need later?

The painted 16 ga steel body resists corrosion in NEMA Type 1 environments; inspect the screw clamps and cover gasket periodically and replace the cover if the screw threads strip or the paint fails.

What limit appears first under sustained use?

The screw-clamp cover locking style is the first limit; repeated thermal cycling can loosen the clamps, so re-torque them to maintain the NEMA Type 1 seal.
