If your sectional sofa keeps moving around, you can fasten the sections together with the Sofa Snap bracket. This hardware is used to connect modular upholstered furniture to form seating rows or groups. The hardware is easily connected to the bottom of the upholstered pieces and connects to the corresponding angle bracket. When not in use the device can be pivoted out of the way. The catch fork is turned and the upholstered pieces are pushed together. The connection is released by lifting.
This piece has flat mounting plates and is designed to mount on the bottom of the sofa. The mounting plate is approx. 1.75" Deep x 2.25" Wide and requires 5 screws to mount. If you do not have a wide enough frame to accommodate this plate, consider the
Compact Angle Mount Sofa Snap.
