Josam Roof Drain Deck Clamp (-1)

The Josam deck clamp is the most dependable means of securing a Josam roof drain to a roof deck. It ensures a permanent bond and prevents damage of flashing and membrane materails caused by movement and vibration. 

It is secured to the underside of the drain body with heavy-duty treaded rods, which can be adjusted to accommodate various slab and deck thicknesses. It is drawn tightly in place against the underside of the deck to form a positive union.

The Josam roof drain deck clamp is an option that must be specified when ordering. Its use is contingent on the type of roof construction.
