Rail Options

* Narrow (Original) Handrails - a close-fitting handrail with a 17" inside dimension. Is an added safety feature by enclosing the body to provide additional upper body support.
* Straight Handrails - Instead of narrowing partway down the stair, the handrail remains straight, giving an additional 3" between the handrail. When you need additional space between the handrails.

We recommend the "Narrow" (Original) handrail for the added safety it provides. Still have questions? Contact us.
