Lowe's entered the do-it-yourself ramp market with what it calls an "affordable, configurable" ramp system. 

The Gatehouse Custom Access Ramp System will be available to consumers in Lowe’s stores and on Lowes.com in spring 2012.

The product, which is the latest extension of Lowe's accessible home products for safety and mobility in the home, was unveiled at the 2012 International Builders' Show in Orlando, Fla.
