Installation Instructions
To ensure straightness, snap a chalk line along the drywall to use as a guide for the 3/8" reveal. Dry fit the bead for length. The Fiber Optic Corner is designed to curve standard 3/8" Fiber optic cable along a gradual 3" radius. One Corner will make a 45º turn. Parts can be used together to make 90º, 135º or 180º turns. The part is designed with a flat area on both sides. When running multiple parts, the flat area must be cut off as shown. You may need to cut off 1 or both sides. See figure 1 for details.
To cut the corner, turn it over as shown in figure 2. With a sharp utility knife, cut along the score mark that is molded into the back of the part. Start at the highest point as shown and then cut off the flanges.
Basic Method: Use a chalk line as a guide to install the bead to the wall, stapling both mud legs every 6-10" with 1/2" long divergent staples.
Superior Method: Liberally apply Trim-Tex 847 spray adhesive to the back of the bead and then to the drywall. Immediately apply to the wall using the chalk like as a guide. Once in position, press the legs into place using the FODW Installation Tool. This ensures the bead will properly bond to the wall. Go back a second time to press the legs into place once the adhesive has tacked up. Staple both mud legs every 6-10" with 1/2" long divergent staples. To keep mud out of the center insert a 3/8" foam backer rod into the center of the Reveal. Be sure not to leave excessive mud buildup on the mud bumps. After final sanding, gently remove the cord from the Reveal. Lightly sand along the edges of the Reveal as needed. Caulk seams with a latex acrylic caulk at all intersections and butt joints.
When painting be careful not to roller too much paint into the Reveal. The center does not require primer and only needs a coat of finish paint to be brushed in.
