Wallbarn Circular Roof Outlet - Spider Gravel Excluder
Our gravel excluders are available in plastic for use in circular drain connectors and roof outlets where the area is covered with a gravel or pebble layer (such as border edges or shingle ballast in an inverted roof system).
Made from polypropylene, they consist of a sturdy cage on the top with strong side bars and slats for the water to drain through.
We have two main designs: the Helix spoke (with three wide spokes) and the Spider fitting (with an angled four spoke design). Both these designs allow for installers to trim the spokes back easily using a sharp knife to fit the diameter of the outlet holes perfectly.
