Review: Stair Stringers - Sturdy, easy to attach to deck, seem well made and meets my needs. good price and should last years
Review: Heavy duty and easy to install. - I use these for my rentals. They are easy to install and heavy duty. They'll last far longer that the treated pine that we have always made stringers out of.

### ⭐⭐⭐⭐⭐ High Quality, and Low Profile
*by P***A on January 25, 2025*

These worked very well for a outdoor deck stair - very heavy duty, well made, and attractive. We wanted the stairs to our deck to have the same floating effect as the deck itself, and these fit the bill perfectly. The also come with an excellent quality hardware pack for multiple installation options. Good value for the price as well.
