International Door Closers 520-AL – Frequently Asked Questions

1) What arm parts are available for the International Door Closers 520 Series size 2 closer arm?
Three separate pieces are sold: the main arm, the regular forearm, and the hold-open forearm. All three come in aluminum finish. If you only broke the forearm, you order the forearm alone rather than a full arm assembly.
2) Do I need the regular forearm or the hold-open forearm?
Pick by how the door has to behave. The regular forearm lets the closer pull the door shut from any position. The hold-open forearm is the one that lets the door stand open at a set point until it is pushed free. Both mate to the same size 2 main arm, so you can change the door's behavior by swapping only the forearm.
3) Can I convert an existing 520 closer to hold open without replacing the whole closer?
Yes. Order the hold-open forearm in size 2 and fit it in place of the regular forearm on the existing main arm. The closer body stays on the door.
4) Are 520 Series size 2 arm parts the right replacement for a fire door closer?
For a fire rated opening, hold-open arms are generally not permitted unless the hold open is electrically released on alarm. On a fire door replacing a broken 520 arm, use the regular forearm, not the hold-open version.
5) Do I have to order the main arm and forearm together?
No. The main arm and the forearms are ordered as separate items, so a property manager replacing only a bent forearm buys that one piece. A full arm replacement means ordering the main arm plus whichever forearm the door needs.
6) What finish do the IDC 520 closer arms come in?
Aluminum, on all three pieces. If your building standard is a painted or plated closer arm, an aluminum arm will read lighter next to it, so match across the openings if appearance matters on the fleet.
