Please note the correct assembly of the E-Z Lock joint shown at the left. The screws or nails MUST be installed only in the edges shown (3 and 4). Installing on the other edges may result in open seams. (Pre-drill if using screws.) 1) Glue both joint edges; slide 1st joint together 2) Push 2nd joint closed 3) Nail or screw this joint first 4) Nail or screw this joint second. Notes: Panels are marked "TOP" - trim from the bottom only. Cap and base pieces are also marked as "CAP" or "BASE". Only use non-corrosive fasteners - galvanized, stainless steel, etc. Always follow glue and paint manufacturer's instructions. *Column must not be allowed to collect water, debris, etc. If the top of the column extends beyond the soffit/beam, the cap must be flashed with lead, copper, aluminum, etc. to prevent accumulation.
