The Ives Plunger Door Holder / Stop FS1154 has been around for about 50 years. Before the 1990's is was known as the Glynn-Johnson 1154, and when they were merged in the H.B. Ives line, the part number was changed to FS1154. This product is constructed of cast brass or bronze that is then plated to the desired finish. Plunger and internal parts are plated steel and provide a 1-1/4" throw for all types of doors. Plunger is easily activated with minimal pressure, releasing instantly with a light tap on the platform lever. The shoe is non-marring rubber that is securely fastened with a screw in flanged cup to prevent movement or loss, and when worn, shoes are easily replaced and are kept in stock as the GJ1154. These are sometimes called pop-up or push down stops. Ships with matching finish mounting screws.
