Perigo A-Frame Supports provide a clean and sturdy solution for supporting pipes high off of the concrete slab. Perigo A-Frames are typically used to support the inlet and discharge pipe in filter applications, but can be used in any application you may need them for. Our A-Frame Supports use the same adjusting process as our standard pipe supports and come painted gray with plated thread and adjusting nut to resist rusting. All stands are a standard height depending on the size of the pipe.
