Patent attributes
A unitary molded corner piece, shaped as a right angle V, has a grooved base with slide openings on adjacent sides of the base for receiving and joining together a pair of orthogonally oriented J channel pieces in an assembly. Right angles of the unitary corner piece are spaced apart and defined by spaced vertical walls shaped as an inner and outer angle. Such angles are joined together at the top of the vertical walls by a closed loop. Two orthogonal oriented J channels slide into the corner base while a J channel vertical wall and a J channel top piece slide within the space defined between the vertical walls of the right angle V of the corner piece. A loose free end of the J channel fits within the adjoining loop of the corner piece. Reinforcing ribs in a J channel receiving pocket both frictionally hold a J channel inserted into said corner piece and guide water as a trough.
