Ives FBPART1035 – Frequently Asked Questions

1) What does an auxiliary fire latch actually do on a pair of fire rated doors?
On a fire rated pair, the inactive leaf is held by a flush bolt at the head and sill. The auxiliary fire latch is the extra latching component that works with that flush bolt so the inactive leaf stays positively latched under fire conditions. Ives supplies it as a separate part, FBPART.1035, for the FB32, FB42, FB52 and FB62 flush bolts rather than building it into every bolt.
2) Do I need to order the auxiliary fire latch separately from the Ives flush bolt?
Yes. FBPART.1035 is a separate accessory part, not something included in the flush bolt carton. When you are specifying FB32, FB42, FB52 or FB62 flush bolts for a fire rated pair, add the auxiliary fire latch as its own line item. There is one model only, so there is no finish or handing to specify.
3) Can a Baldwin 0413 mortise door bolt be used in place of the Ives FBPART.1035 auxiliary fire latch?
No. The Ives FBPART.1035 is an auxiliary fire latch made to work with FB32, FB42, FB52 and FB62 series flush bolts, supporting the fire-rated performance of that flush bolt assembly on the inactive leaf. The Baldwin 0413 is a contemporary mortise door bolt with a 2-3/4 inch backset from the Estate series, supplied less turn piece - a standalone bolt with its own mortise prep, not a component that installs into an Ives FB series flush bolt. If you are servicing an FB32/FB42/FB52/FB62 flush bolt, order the Ives part; the Baldwin bolt would require a different door prep and does not carry the FB series fire latch function.
4) Is there more than one version of the FBPART.1035, by finish or handing?
No. The auxiliary fire latch is offered as a single model, FBPART1035. There is no handing to call out and no finish selection, which makes it straightforward to stock for a building standardized on Ives FB series flush bolts.
5) Can I use this Ives fire latch on a single door instead of a pair?
No. It is an accessory to FB32, FB42, FB52 and FB62 flush bolts, and flush bolts go in the inactive leaf of a pair of doors. A single door has no inactive leaf, so there is nothing for this part to work with. For a single opening you want the lock or exit device latching into the frame strike instead.
6) I have a Baldwin mortise door bolt on my pair, will the Ives fire latch fit it?
No. The Ives FBPART.1035 is dedicated to Ives FB32, FB42, FB52 and FB62 flush bolts. A Baldwin 0413 contemporary mortise door bolt is a different bolt entirely, with a 2-3/4 inch backset and no stated tie to this Ives accessory. Mixing brands on a fire rated pair is not something to improvise; match the accessory to the bolt already in the door.
7) Is this the right part for replacing a missing fire latch on an existing Ives flush bolt?
If the existing bolt is an Ives FB32, FB42, FB52 or FB62, yes, FBPART.1035 is the replacement auxiliary fire latch for it. Identify the series stamped on the bolt or on its face plate before ordering, because the four covered series are the limit of what this part serves.
8) I need a latch for a fire-rated pair of doors - are Baldwin Estate 5510 knob latches an option?
They are a different class of product. The Baldwin Estate 5510 2-3/8 inch knob latches are residential-style knob latches sold in passage and privacy functions, including a version with a full lip strike - they are the latch behind a knob set on an active door leaf. The Ives FBPART.1035 is an auxiliary fire latch that integrates with FB32, FB42, FB52 and FB62 series flush bolts to support fire-rated door assembly and emergency egress requirements on commercial openings. For a fire-rated pair with FB series flush bolts on the inactive leaf, the Ives part is the matching component.
9) Where do I find the mounting and prep details for installing this fire latch?
Installation follows the parent flush bolt. Use the instructions that come with the FB32, FB42, FB52 or FB62 bolt you are pairing it with, and the Ives architectural hardware products catalog for the series details. The fire latch integrates with the bolt already prepped into the inactive leaf rather than requiring a separate door prep of its own.
