Large Frame 3-4 Bar

The Large Frame 3-4 Bar is the bottom-most horizontal bar, designed to sit on the floor and connect to the left and right vertical bars of Retrotec’s large-sized blower door frames. This extended bar provides essential foundational support, ensuring a stable base for the larger frame during air leakage testing in larger openings.
