Molding Installation Guide-End Cap
Install the flooring planks including the underlayment by leaving a 1-1/8”inch (28mm) gap for the installation of the End Cap molding.
Center the U-track between the carpet and the flooring planks and screw it to the sub-floor by using #6x5/8”screws.
Gently press the molding into the track starting from one end to the other. NOTE: Do not try to push the entire molding in at once by pressing it in from the top.
