Aluminum Classic Drain

The Aluminum Classic Drain is manufactured from spun aluminum. Its one-piece construction is designed for quick installation in new connection and ponded roof applications. The drain can be connected by using the mechanical coupler provided. The drain flange has six welded aluminum studs to secure the aluminum clamping ring and six pre-drilled fastener holes for attachment of the drain to the roof deck. The drain flange has a depressed sump area to facilitate the drainage of all water from the roof surface. The cast aluminum strainer dome is secured to the cast aluminum clamping ring by means of 3 stainless steel screws. Available in 3-in., 4-in., and 6-in. sizes along with options of a plastic dome or cast aluminum SuperDome.

Features & Benefits

  • One-piece seamless body is made from 0.125-in., 11 gauge spun aluminum. It provides strength and durability without separation of the flange from the stem.
  • Pre-punched flange insures consistent, stable attachment to the roofing substrate eliminating the need for an under-deck clamp.
  • Heavy-duty cast aluminum strainer dome and clamping ring - designed to be durable and to ensure a uniform compression seal of the membrane. A plastic dome or the cast-aluminum SuperDome are available options.
  • No-hub coupler has stainless steel bands that connect with PVC or cast iron plumbing, and will work with schedule 40 or 80 water leaders.

Application

The Aluminum Classic New Connection Drain is designed for installation in roof areas that pond water or new roof construction. The drain comes complete with strainer, clamp ring, no-hub banded coupler and pre-punched drain flange for top-side securement, eliminating the need for clumsy underdeck clamps.

As with all building materials it is the responsibility of the installer to review its usage with a design professional to confirm safety, compatibility and acceptance with the roof cover manufacturer as well as local building codes.
