Frequently asked questions

Do I need a starter kit first?

Yes. The add-on kit includes only one post, so it attaches to the end post of a starter kit or an existing run.

How many add-on kits do I need?

Divide the total run length by the rail length you chose, subtract the first section covered by the starter kit, and order that many add-on kits.

Can I mix rail lengths?

Yes. Each kit lets you pick its own rail length, so you can fit runs to your floor layout.

Where does it ship from?

Kits ship from our Dallas, TX warehouse to sites across Texas and the US.
