The last piece to install on the front is the chrome trim cap. Find a nice looking place to put it on the end of the header rail, and pull the finishing strip around to be positioned under the trim cap. Cut the end of the finishing strip so that the strip will end inside of the trim cap just past the center hole so that the nail will pass through the end of the strip. Drive the nail through the center of the cap and the end of the finishing strip into the header rail to hold the cap and strip securely. Be careful not to smash the trim cap in the process. Also install the trim cap an the other side in a similar manner. Pretty little thing, isn't it? All finished up front.
