These hard plastic Horseshoe Tile Spacers are precision injection molded for accurate, evenly spaced grout joints. They are suitable for use with all types of tile installations regardless of tile thickness or tile layout pattern. The large horseshoe design makes them easy to grasp for placing and removing. The solid construction of these spacers means they won't crush or compress even in vertical installations of heavy, large format tiles. Being solid also means that mortar will not load up in these spacers that can occur with hollow backed spacers. The non-tapered design assures these spacers stay in place and won't be pushed out of wall tile installations. These durable spacers can be reused many times and are color coded for easy size identification. Made in the U.S.A. with recycled plastic.
