The DE Small Hold-Down Assembly (Complete) (cataloged across residential and light-commercial vertical DE pressure filter lines by manufacturers such as Hayward, Pentair / Pac-Fab, Waterway, and aftermarket specialists like Filbur) is the upper structural retainer bridge designed for compact grid clusters. It is sized specifically for smaller filtration vessels utilizing curved or straight grid sets (such as 24, 36, and 48 sq. ft. configurations) where a large commercial bridge would be oversized.
The assembly spans the top of the grid cluster to lock each element into uniform alignment. Compressing the top edge prevents the elements from lifting off the bottom manifold, chattering, or shifting under high differential pressure during pump starts and backwash cycles.
