Made from durable composite fiberglass, the D-Plate is designed to withstand deflection caused by heavy soil loads.  The strength of the 1/4″ fiberglass D-Plate allows for the marriage of the larger diameter poly riser over top of the smaller opening of the square concrete d-box.

The D-Plate can also be used as an adapter for any riser system over a septic tank opening.  The D-Plate’s large 36″ x 30″ footprint provides coverage and security over any large septic tank opening that you are trying to gain access to with poly risers.

To install, apply sealant (i.e. Conseal Mastic, I/I sealant, Orenco ADH200, etc.) around the rim of the exposed concrete D-Box.  Fasten the D-Plate to the D-Box with concrete fastening screws (i.e. TapCons).  Fasten appropriate Adapter ring over the opening of the D-Plate with 5/16″ x 1″ self-tap screws and sealant.  Adapter Ring Models are listed below.  Use desired Risers and Lid to extend to grade.
