Corbin Russwin 503F56-7 – Frequently Asked Questions

1) What is the Corbin Russwin 503F56-7 and where does it go on the door?
The 503F56-7 is the top strike for Corbin Russwin ED7000 Series exit devices. It mounts at the head of the frame (or the head of the door on a pair) and receives the top latch of the vertical rod device, so the latch engages properly when the door closes. It is a replacement part, not a complete device.
2) Will the 503F56-7 top strike work with a Von Duprin or Sargent vertical rod device?
No. The 503F56-7 is built specifically for the Corbin Russwin ED7000 Series and is engineered to that device's mounting and latch geometry. For another manufacturer's vertical rod device, order that manufacturer's own top strike. If you are unsure what you have, check the device chassis for the ED7000 marking before ordering.
3) Can I use this strike on a fire rated exit door?
Yes. The 503F56-7 is a fire rated top strike intended for use in fire-rated door assemblies, which is the point of the part: on a fire-rated opening the top latch has to engage and hold, and a non-rated strike compromises the assembly. Use it where the ED7000 device is installed on a labeled door.
4) My building's fire doors won't latch at the top. Is replacing the top strike the fix?
Often, yes. A worn, bent, or wrong top strike is a common reason a vertical rod device fails to latch at the head, and an unlatched fire door fails inspection. The 503F56-7 is the OEM top strike for ED7000 devices and restores correct latch engagement. Also check the top rod adjustment while the strike is off, since a short rod produces the same symptom.
5) Is this a genuine Corbin Russwin part or an aftermarket equivalent?
Genuine OEM. The 503F56-7 is a factory-authorized Corbin Russwin component, which matters on a fire-rated opening where an inspector can question non-OEM substitutions in a labeled assembly.
6) Do I need anything else besides the top strike to complete an ED7000 repair?
The 503F56-7 covers the top strike only. If the device also latches at the threshold you may need the bottom strike or floor strike, and worn top and bottom rods or latch assemblies are ordered separately. Pull the device and confirm which components are damaged before ordering, since the strike alone will not fix a bent rod.
7) Is the 503F56-7 rated for commercial traffic or is it a residential part?
Commercial. It is specified for commercial door hardware installations such as offices, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential properties, where exit devices see heavy daily use and the opening has to stay code compliant.
