This document is the Nyloplast Double Base Plate Sell Sheet. General description, features and curb inlet structure detail are included.

The Nyloplast Double Inlet Structure was introduced in order to maximize inlet capacity in a single, economical structure. It is a more cost-effective solution compared to requiring installation of multiple side-by-side structures at road sags and traffic areas where you need to reduce ponding.

Features listed are ideal for traffic installs, exceeds H-20 loading. Ductile iron, which is heavier duty and longer lasting. Great for roads and parking with high flow. ASTM rated A536 grade 70-50-05 frame and grate. Available only on 30” basins. Double grated inlet capacity on one structure to eliminate excess excavation costs and construction and installation of a second structure.

Installed cost savings with one light weight structure and built-in pipe connections. Water tight joint connections to prevent premature degradation of structure and surrounding road base. Easy field adaptability.

The nyloplast double 2” x 3” curb inlet structure on 30” drain basin illustration shows the ductile iron frame, hood & grate, 18” minimum width & 8” minimum thickness guidelines, minimum pipe burial, variable invert heights, integrated base plate to match basin, watertight joint, traffic loads, variable sump depth and backfill material that should be crushed stone or other granular material.
