Flights

FRP - Channel Flight / Standard
Standard "C" Channel Flight, Fiberglass Pultrusion

FRP - Channel Flight / High Strength
High Strength variant of the "C" channel flight, designed for heavy duty applications and tanks up to 22 ft wide.

FRP - HMAX Flight / Extreme Duty
Designed for tanks up to 36 ft wide and extreme service requirements. Unique shape eliminates needs for filler blocks.

Aluminum Flight
Made of T-5 Aluminum these flights do not corrode and do not require drilling or notching. Environmentally friendly, these flights have salvage value at the end of their service life vs paying hazardous material disposal fees.

Flight Components

Filler Blocks
