A Hader bar nylon retention rider is a plastic clip that snaps onto a metal bar, providing retention and stabilization for a denture. The Hader bar is attached to implants or teeth, and the nylon rider clicks onto it to hold the denture in place. These riders come in different colors (white, yellow, red) to indicate varying levels of retention.

Various forms of the device are intended to connect a lower partial denture with another lower partial denture, to connect an upper partial denture with another upper partial denture, to connect either an upper or lower partial denture to a tooth or a crown, or to connect a fixed bridge to a partial denture. The device typically includes fixers (e.g., clasps, sleeves, or screws).
