ACO HP Overflow Aluminium Roof Outlet, available with a Dome grate in sizes 75mm & 100mm.
Overflow modules are easily attached to an appropriate circular 50/75HP or 100/150HP rainwater outlets in applications where grating blockage from leaves, for example, would lead to an excessive accumulation of water on the roof area. Unplanned excess water on the roof area can lead to over-spill to the sides of the building and significantly increase the load applied to the roof structure.
Overflow units are supplied with a PVC tube 250mm long that can be easily cut on site to the maximum permissible overflow height required for the application. Overflow units are used in conjunction with an appropriate spigot outlet unit.
Product Code: 75/100/HP/OF
