These legs are great for all kinds of furniture like sofas, cabinets, curio cabinets, beds ottomans etc. Made from 93% optically clear American made acrylic, these legs are the most beautiful addition to any piece of furniture that you may be contemplating changing out the wooden legs for. We make these right here in southern California, outside of Los Angeles. We have been making acrylic legs for years as an application for all kinds of furniture. Just choose which type you would prefer depending on the installation, with a threaded center thread or a top plate with 4 countersunk holes for screws. The price is for a set of four and includes the brackets for attaching to the bottom of the sofa or cabinet and the screws for attachment. We can make any height for you if the standard 4" or 8" or 16" does not work for you. Just let us know. The 8" and 16" are in another location in our store. Thank you for shopping with us at PlasticMart.
