How can I get a 8 foot section

Hello, and thank you for your interest in Trex Railing. The Enhance railing line is only manufactured in 6' rail kits. However Trex offers another railing line called Select which is identical in design to Enhance. The only difference is how the Select Railing line is designed in length. The Select rail line is manufactured at "on center dimensions" which means the 8' rail kit would have an actual rail length of 91.5". If this would work for your longer sections then you may order Enhance 6' rail kits where needed, and then special order the 8' Select rail kits where needed. I hope this helps! Thanks, Tori - Trex Customer Care Team
