Internationally regarded as the go to source for door accessory hardware, IVES is the clear cut brand to use for your building project. This is no exception when it comes to the IVES plunger door stops. Having all the hardware included, the IVES FS1154 plunger door stop is exactly what you need to hold a door open. Office, warehouse, and institutional settings are a few of the places you will find plunger door stops. Each plunger door stop is heavy-duty, being constructed from cast brass or bronze. This provides maximum strength, and helps resist damage to the unit like no other. Operating these plunger door stops could not be easier. Once the unit is fastened to the door, a gentle press of the sole of the foot to the plunger, will engage the spring and slide the round, non-marring, replaceable rubber shoe onto the floor. Release door with light tap on unit's platform lever.
