Does a great job getting my 27" to match my 56" height and feels very sturdy.
Knocked off a star because I had to cut 4 notches into my box on the 2 front sides for the risers to clear the bent over bottom edge of my 27" box.

I don’t normally write reviews but communication, ease of use on the website, quality of the products, fitment to my U.S. General 27” box, it was flawless. I will be ordering from rattan again. What an excellent company that from cradle to grave is solid.
