Wallbarn EPDM Circular Roof Outlet (Smooth Flange) - H240mm - D75mm

CIRCULAR ROOF OUTLETS ARE MANUFACTURED WITH A SMOOTH FLANGE WHERE APPLICATORS ARE BONDING OR MECHANICALLY FIXING DRAIN CONNECTORS TO THE WATERPROOFING MEMBRANE ACROSS THE FACE OF A FLAT ROOF OR TERRACE

The spigot is 250mm long and is inserted down inside of the HDPE drainpipe. This gives ample assurance that no water can back up behind the rubber and onto the deck. The spigot is slightly cone shaped and ribbed. This helps with installation into the hole, and prevents water passing back up behind the spigot.

The mouth of the shank has a series of internal serrations so the gravel guard or leaf excluder can be fitted easily and securely. Remember installers of these outlets will always need to insert leaf guards or gravel excluders (this will be a hyperlink to “accessories” page) into the moth of these connectors to prevent the pipes becoming blocked.

They are positioned throughout the roof deck at intervals approximately 25 – 30m2 apart to handle the amount of potential UK rainwater run-off.
