Sargent 63-3904 – Frequently Asked Questions

1) What is the Sargent 63-3904 and what does it do on a door closer?
The 63-3904 is a hold open kit with a bumper for Sargent door closers. It adds or restores hold-open function so the closer will park the door in the open position instead of closing it, and the bumper takes the impact at the hold-open point so the door and wall surfaces don't get beaten up. It is sold as a replacement part, not a complete closer.
2) Will the Sargent 63-3904 hold open kit work on any Sargent closer arm?
No. The 63-3904 is built for channel-type closer arm configurations only. If the closer on the opening uses a standard parallel arm or a regular arm without a channel (track), this kit is not the part for it. Check the arm on the door first: it has to be the channel style for this kit to mount and operate.
3) Do I have to replace the whole door closer to get hold-open, or can I add it to the closer I already have?
If the existing Sargent closer uses a channel-type arm, you can add hold-open with the 63-3904 kit rather than swapping the closer body. That is the point of the part: it restores manufacturer-specified hold-open function on a closer that is otherwise working, which keeps the opening down for a shorter maintenance window. If the arm isn't channel type, hold-open has to come from a different arm or closer instead.
4) Is the Sargent 63-3904 hold open kit rated for commercial traffic, or is it a residential part?
It is a commercial part. Sargent lists the 63-3904 as commercial-grade and it is used in offices, schools, healthcare facilities, retail, industrial and warehouse buildings, multi-tenant residential properties, and government buildings. For a property manager standardizing hold-open across a building's Sargent closers, it is the same part on every channel-arm opening.
5) Does the Sargent 63-3904 come with a bumper or do I order that separately?
The bumper is part of the kit. You are not buying a separate stop or cushion on top of it. The bumper sits at the hold-open position so the door stops against it rather than driving into the wall or the arm hardware.
6) I need a hold-open on a fire door. Can I use this kit?
A mechanical hold-open kit parks the door open and keeps it there, which is not what a fire-rated opening needs. Fire doors require a hold-open that releases on alarm, normally an electromagnetic hold-open or a fusible-link arrangement. Use the 63-3904 on non-rated openings where a door is meant to stand open, such as a corridor or a loading area.
7) What should I check on the door before ordering the Sargent 63-3904?
Two things. First, confirm the closer is a Sargent unit with a channel-type arm, since the kit is made for that arm configuration. Second, look at where the door swings to when held open: the bumper in the kit takes the impact, so you want clearance at that point rather than the door landing on trim or a wall fixture. Beyond that, this is a direct replacement component and does not require a different closer body.
