Weather seal device for conduit extending through ridged surface

A weather seal device for providing a seal between a surface having longitudinal ridges and an elongate member extending therethrough, said device comprising an apertured base member of resilient deformable material to be located in use in superimposed relation on the surface with the elongate member extending through the aperture, a sleeve member of resilient material integral with the base member and projecting from one side thereof, said sleeve member enclosing said aperture in the base member so that in use the elongate member also extends through the sleeve member, the end of the sleeve member remote from the base member being adapted to in use sealably engage the exterior of the elongate member, said base member having a marginal edge portion extending along one edge of the base member,a marginal portion spaced from the junction of the sleeve member and the base member and to in use be positioned to extend in a direction generally inclined and across the direction of the longitudinal ridges of the surface, said marginal edge portion being contoured along its length in a direction normal to the plane of the base member, so that the length of the marginal edge portion measured along the contours is greater than the linear length thereof, when the measurements are made when the edge portion is in the free as produced state, said base member in the free, as produced state having a substantially flat area between the contoured marginal edge portion and the junction of the base member and the sleeve member, said contours in the marginal edge portion in use being deformed to follow the contour of the surface having longitudinal ridges with limited alteration of the linear length of the marginal edge.
