4 Count Universal Slider Door / Window Clip & Block for Security Bar Dowel Stick. Really simple to use and install and intended to work with dowels or rods from 1-1/16" to 1-5/16" in diameter. An extra layer to secure your door, as a rod by itself can be bumped or shaken out by a savvy enough intruder, especially in a vertical sliding window. Group of 4, all brand new, sealed.
