Level out furniture legs and move furniture easily with these Fusion Feltac furniture glides. The glides have a felt base that ensures they move smoothly and quietly over hardwood, laminate, linoleum or ceramic surfaces. The furniture leg levellers have a threaded stem that allow for adjustable installation from 1/4" to 20" (6.35 mm - 508 mm) to achieve just the right height. The felt is fused on for a durable design, and the round shape and white base complement a wide range of furniture leg styles. They have a 1 1/4" (32 mm) inside diameter and a 1 1/2" (38 mm) outside diameter. The package contains four furniture glides.
