Is there a gate that goes with this product and matches the white rail/black baluster color scheme?

Hello, and thank you for your interest in Trex Railing. The only gate offered by Trex is the all aluminum gate rail kit offered in a 48" length only in all black, white, or bronze aluminum. The Aluminum gate rail kit is also offered in 2 rail heights of 36" or 42" and with 2 baluster options of square aluminum or round aluminum. Therefore the aluminum gate rail kit does not match the Enhance rail kit exactly, but the all Charcoal Black aluminum gate rail kit with round aluminum balusters would contrast nicely with the Enhance Rail kit due to it containing round black aluminum balusters as well. I hope this helps answer your question. Thanks, Tori - Trex Customer Care Team
