Rear Outlet Drainage Channel

The Rear Outlet Drainage Channel addresses an installation constraint that no standard channel can solve: the floor slab cannot be penetrated for a drain pipe, or the plumbing must be routed horizontally through a wall rather than vertically through the floor. In these situations, the rear outlet is the only viable configuration — the drainage pipe connects to the back of the channel body, the channel installs tight against a wall, and the pipe runs horizontally through the wall to connect to the drainage stack. No floor penetration is required.

This configuration is common in ground-floor renovations where breaking the floor slab is structurally impractical or contractually prohibited, and in basement installations where the drainage system must follow the perimeter wall rather than cross the floor. The channel body is fabricated to the specific project requirements — length, width, and height specified at order. AISI 304 or 316, 1.5 mm walls, 2 mm removable grating, built-in 0.9° slope toward the rear outlet.
