Sofa Snap Sectional Couch Connector (Flat HD Fixed Mount #345) If your sectional sofa keeps moving around, you can fasten the sections together with the Sofa Snap bracket. One Sofa Snap bracket per separation in your sectional is generally sufficient. Some high-traffic areas will benefit from two brackets per separation to ensure a secure hold. Designed for furniture with a wooden frame across the bottom edge which is at least 2 inches wide. If yours is less than this, look at the #917 or #938 Sofa Snap brackets. Screws are included. Installation is simple, instructions can be found on the Sofa Snap website. LIFETIME SERVICE POLICY
