Through Wall Drain Outlet 100mm x 100mm

The EPDM Rubber Through Wall Drain Outlet is a synthetic EPDM rubber outlet for use on flat roofs with parapet walls to form a through wall outlet so that water can be dispersed into a drain hopper or a similar soak away.

The EPDM Rubber Through Wall Drain Outlet 100mm x 100mm requires a hole size of 105mm X 105mm.

This can be used with EPDM Rubber roofing membranes and can be fitted above or below the membrane to suit the situation. EPDM Flashing Tapes and Tape Primer should be used to create waterproof finish in areas where water ingress is possible.
