508 x 508mm Galvanised Mounting Frames

A 508 x 508mm galvanised steel mounting frame with a foam gasket seal, designed to securely hold standard-depth HVAC filters within ductwork or air handling units. The galvanised finish provides corrosion resistance for long-term installation in humid or outdoor-adjacent environments. The foam gasket ensures an airtight seal around the filter perimeter, eliminating bypass and maintaining filtration efficiency.
