Zurn Z884 Perma-Trench
The 4” Z884 Series provides a sturdy channel drain for residential drainage and depth-restricted installations. This 4″ wide modular drainage system features a inegral top frame, interlocking ends, and a radiused bottom.
Lightweight & Durable
Each channel interlocks to create a smooth seam, eliminating water leaks that weaken concrete and lead to freeze-thaw damage. Made from HDPE, the Z884 is lightweight but durable enough to resist heavy traffic and corrosive materials.
