Sargent 63-3903 – Frequently Asked Questions

1) What does the Sargent 63-3903 hold open kit actually do?
It is a channel type hold open kit for Sargent door closers. Fitted to a compatible Sargent closer, it lets the door be held in the open position instead of closing on every cycle, which is what facilities want on high traffic passageways and for accessibility. It is a replacement part, not a complete closer, so you are installing it onto an existing Sargent closer.
2) Will the Sargent 63-3903 hold open kit work on any brand of door closer?
No. The 63-3903 is built as a Sargent door closer part and is intended for compatible Sargent closer installations only. It is the channel type version, so the closer it goes on has to be a Sargent unit that takes a channel type hold open arrangement. Don't plan on it fitting an LCN, Norton or Dorma closer.
3) My Sargent closer stopped holding the door open. Do I have to replace the whole closer?
Not necessarily. If the closer body still controls the door properly and it is the hold open function that has failed, the 63-3903 channel type hold open kit restores that function as a component swap on a compatible Sargent closer. You only go to a full closer replacement if the body itself is leaking or has lost closing control.
4) Is the 63-3903 a genuine Sargent part or an aftermarket copy?
Genuine Sargent. The 63-3903 is the manufacturer's own replacement component, which matters on a closer that was originally specified as Sargent because the hold open hardware has to match the arm and channel geometry of the original installation.
5) What is the difference between a channel type hold open and a regular hold open arm?
Channel type refers to how the hold open is carried: the arm rides in a track or channel rather than acting through a standard parallel or regular arm linkage. The 63-3903 is the channel type kit, so it belongs on a Sargent closer set up with a channel arm. If your closer uses a conventional swing arm, this is not the kit for that opening.
6) Is the Sargent 63-3903 hold open kit rated for commercial use or is it a light duty residential part?
Commercial. The 63-3903 is classed as commercial door hardware and is the part used on closers in office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings, where the closer sees constant traffic.
