I plan to install New Standard planks (Hatteras) on concrete subfloor and will require an end cap at the door. Is there a cap available in the color range? How do I install the end cap to the floating floor? Lastly, is a rubber floor ramp a viable option? Thank you.

A reducer or end cap would be recommended for this space. Coordinating end caps in this series are not currently available. The transition piece typically installs directly into a track and onto your subfloor. Rubber flooring ramps are a suitable solution as well. Be sure to follow manufacturer's installation instructions for any trim molding.
