Systems and methods are directed to securing products to product display assemblies. In one aspect, a product display assembly includes an adjustable bracket for securing a product. The adjustable bracket for securing a product comprises a first bracket arm, a second bracket arm, and a base comprising a top plate, a bottom plate, a gear located between the top plate and the bottom plate, and a lock that is controllable between a locked state and an unlocked state. The first and second bracket arms extend laterally outward from opposite sides of the base. The gear is located between the top plate bottom surface and the bottom plate top surface. The lock compresses the top plate and the bottom plate together to restrict extension of the first and second bracket arms relative to the base.
