The Metal Man™ - Aluminum Hinge Handles hold any size of wooden board to create professional a-frame signs (also called sandwich boards). Aluminum construction provides high strength and high durability. It's more stronger than plastic, especially in the cold, and more durable than steel, which can rust. These hinge handles allow 360° rotation, providing four sign faces. These hinge handles produce a stable sign that can fold flat for easy storage. Unlike a slide-in A-frame, this product is not restricted to any particular sign panel size. It is comparable to the Image One Impact Sooper Hinge.
Don't forget t-nuts and screws. They're are sized specifically for these hinge handles and make installation a breeze.
