Timloc Invisiweep Concealed Wall Weep Vent – Black | Discreet Cavity Drainage for Masonry Walls

The Timloc Invisiweep offers a modern, discreet solution for draining moisture from cavity walls without disrupting the look of your masonry. Designed to blend seamlessly into the mortar line, this low-visibility weep vent delivers exceptional performance in brickwork, blockwork, and stonework, making it the preferred choice for both residential and commercial projects.
