A hollow housing has a closed top, a closed back, a pair of side walls formed integrally with the closed top and the closed back, an open front and an open bottom. The open front is adapted to abuttingly engage a flat exterior surface of a wall of a building. The open bottom receives an uppermost end of a vertically oriented conduit. A throughbore is formed in the wall so that at least one cable enters the vertically oriented conduit from a lowermost end, extends through the lumen of the conduit, makes a gentle right angle bend in the hollow housing, and extends through the throughbore into the interior of the building. Sealant is then introduced into the hollow housing through a port formed in the closed top to seal the throughbore.
