The Universal 20k Slate Vent is available in slate grey or dark slate to blend in with the roof tiles. KG9795-0429.
Installing a 20K Slate Vent
To accommodate the downpipe, cut a hole in the roofing underlay and place the Slate Vent. Use Klober underlay seal to maintain the underlay's integrity. Nail the rigid base on each side of the batten. Cut the profile of the vent body into the two slates immediately above the Slate Vent to ensure a proper fit.
Notice: When using 500mm x 250mm (20" x 10") slates we advise to detach the front section of the Slate Vent base by following the guidelines on the underside. Cut the adjacent slates on the same course and the slate directly behind the Slate Vent to fit. Clip the Slate Vent base with a slate rivet.
