The Thunderbird 2" No-Hub Balcony Deck Drain (BD2NH) is a copper-flashing drain built for exterior waterproofed decks, balconies, and patios. The 16 oz copper flashing is sandblasted for excellent bonding with waterproofing membranes, and the stainless steel snap-in grate keeps debris out of the 2" no-hub outlet.
Typical applications: balcony and patio waterproofed deck systems, single-ply membrane installations, liquid-applied membrane (PMMA, urethane) decks, and copper-clad architectural details.
