Acudor 3" Aluminum Under Deck Clamp

Under-deck clamps are recommended to provide a secure, long lasting installation of the roof drain on all but poured-in-place installations. Roof drains must be firmly secured to the roof with an under-deck clamp, otherwise, due to snow loads, rain loads and regular expansion and contraction, the drain will work in and out of the roofing, causing roofing membranes to flex and fail.
