Merrimack™ Railing

The new DuraLife Merrimack Railing features a beautiful design that meets commercial requirements for structural integrity.

Introducing the Merrimack Railing System

It's Your Choice. We Just Make it Easier.

DuraLife Merrimack Railing is made from an engineered PVC composite material that won't absorb moisture and reduces the rattles and squeaks commonly associated with vinyl railing.

Merrimack Railing Performance Features

Deck Board Top Rail

The Merrimack deck board adapter fits on top of the rail and allows for the addition of a DuraLife deck board. The perfect solution for resting drinks or plates while entertaining friends and family on your deck!

Contoured Rail Design with Architectural Details

Merrimack Railings offer attractive options like hidden bracket hardware, LED lighting and composite deck boards for the top rail, creating a handy, flat top rail perfect for entertaining.

Innovative Design

Innovative dovetail, level rail brackets and collars allow you to simply slide an assembled rail section onto adjacent posts without any unsightly mounting hardware.
