1. LITTLE ITEM WITH BIG BENEFITS The MechWare support bracket is perfect for applications requiring space constraints and/or flexibility, such as that of the kitchen, laundry room, retail/grocery stores, RV, boat, warehouses, industrial, garages, maintenance storage, and office/residential storage. Apply them to table legs or surfaces for DIY table or bed folding legs, folding workbench projects, fold down desk extensions, and so on. 2. SELFLOCKING AND SIMPLE FOLDING – The brackets have a springactivated 'positive lock' that ensures stability by locking in the open position for added security. Press the latch to fold down the table or work surface when not in use to create additional space. Before being fitted, these brackets are stiff to open. It is preferable to use two pliers to bend the plate inward or outward in order to test how these brackets perform.
