This year Deckorators introduces the all new aluminum classic AXL rail panel. This system allows you to choose the round (classic) or square (estate) balusters that will come with the boxed kit. Available colors - Satin Black - Matte Black - Textured White.
A railing kit will contain the following:
2 - Aluminum Rails with your choice of balusters installed
1 - In-line hardware kit with 4 - inline brackets - 8 - #8 x 3/4" and 4 - #6 x 1/2" SS installation screws
All that you need to do is buy the posts.
The narrow 2.5" posts anchor directly to your deck structure and include a matching post cap and base trim
Also available are Solar or Low Voltage LED Post Cap options
I think this is simple to install and priced well.
