Middle Atlantic Z4 Series Seismic Brackets

A rack base decides whether the frame rolls, sits on a riser, or is anchored for seismic duty, and it sets the finished height of everything above it. The Z4 Series Seismic Brackets range is the base option, ordered to match the frame's footprint.

9 part numbers on this page, BGR-ISO-Z4 through WRK-Z4, covering 22 - 30 in wide, 1 - 9 in high. Every part number listed here is a current Middle Atlantic item; pick the one that matches your frame and we ship it as ordered.
