Stair Stringers

Many do-it-yourself deck builders find stairs to be the most daunting part of any deck project. But Universal’s wood, pre-cut stair stringers let you add stairs to your new wood deck in a snap. It’s easy to “notch and botch” stairs by cutting them improperly, so our stair stringers are pre-cut to save you time, money, and materials. You don’t have to measure, mark, or cut—we’ve already done it for you! Stair stringers are available with a 6-3/4” rise and an 10” run, and in 3-step, 4-step, and 5-step varieties. Pre-cut 2x12-48" step treads are also available in select regions for easy installation. Universal’s pre-cut stair stringers resist decay and weather—just like our other wood decking products. Build your deck to last with Universal’s solid wood stair stringers.
