Installation is as easy as 1-2-3. The modular components simply swing-lock together often without the need to enter the water. The QMP Pier System has two major components; an 8'x 3' straight pier section and a 5'x 3' connector pier with three of the same swing-lock bolt less connections for branch piers. The QMP Pier System has slots molded into the front corners of the module for legs madeto fit a standard 2"x 4" . (lumber not supplied). By simply cutting the 2"x 4" to length and locking the modules together, a pier can be constructed quickly and easily.
