It’s Fast – Contractor can install roof drain in half the time as conventional methods … a superior method of installation using a bolt-down system that secures roof drain assembly integrally to roof deck.
It’s Secure – Unique design combines a traditional roof sump receiver with a deck clamp to provide a more secure, long-lasting installation of the roof drain. Available for all main roof drain sizes - Z100 (15˝), Z121(12˝), Z125 (8˝)
It’s Safe – Contractor can install roof drain from the top of the roof eliminating costly and dangerous assembly of components from the underside of the roof deck, leaving the pipe connection as the only remaining task from under the roof deck.
The Zurn TOP-SET® Roof Drain Deck Plate (catalog option -DP) features ease of installation, allowing the installer to move onto more projects sooner. The TOP-SET® Deck Plate allows for the entire roof drain assembly to be installed from the topside of the roof. Separate underdeck clamps and roof-sump receivers are no longer necessary … the deck plate acts as both. Only the pipe connection is completed from the underside of the roof.
Zurn manufactures three different sizes (-DP) deck plates for a trouble-free fit for all [8", 12" and 15"] diameter Zurn drains. The deck plate also includes strategically placed slots allowing versatile securing arrangements for various roof decks. The deck plate is constructed of 14-gauge steel with a corrosive-resistant finish.
