Ives FB457 12 US26D – Frequently Asked Questions

1) Does one FB457 flush bolt secure a fire rated pair of doors, or do I need two?
Two. The FB457 is UL Listed for 3 hour fire rated openings only when a top and bottom bolt are both used on the inactive leaf. Order in pairs for any fire rated pair of doors. Single-bolt use is fine on a non-rated opening where you only need the inactive leaf held at the head or the sill.
2) What does the 12 inch rod length on the FB457 actually measure, and how much bolt engagement do I get?
The 12 inch dimension is measured from the center of the flush bolt body to the bolt tip, not the overall part. The bolt tip is 1/2 inch diameter with 3/4 inch throw and 3/4 inch backset, plus 7/8 inch of vertical adjustment to dial in engagement after the door hangs. The bolt body itself measures 1-1/4 x 6-3/4 x 1-1/8 inches.
3) Does the Ives FB457 meet ANSI/BHMA for a commercial spec?
It certifies to ANSI/BHMA A156.16 under function number L04261, and it is a commercial grade product. That is the auxiliary hardware standard a facility spec or submittal for flush bolts will call out, and the L04261 designation is what you write on the schedule.
4) Should I use a manual flush bolt like the FB457 or an automatic flush bolt on my pair of doors?
Manual is the right call when the inactive leaf stays put most of the time, a stockroom or an equipment room pair where staff rarely open both leaves. Someone has to reach up and throw the bolt by hand. If the inactive leaf gets opened regularly, or egress code on the opening will not allow a leaf that must be manually released, go automatic instead, for example the ABH 1860P/1862P automatic flush bolt pair, which is fire rated 3 hour with a thermal lock.
5) My double doors are wood, not metal - is the Ives FB457 still the right flush bolt?
The FB457 is designed specifically for metal door applications, with a round bolt head that needs only a punched hole in metal frames. For paired wood doors, the Adams Rite 1877 is a cylinder-operated flushbolt built for that construction, and the Delaney 6 inch square end solid brass flush bolt and Delaney 7 inch slide type mortise in flush bolt are mortise-style bolts for wood stiles. The Delaney units mortise into the door edge, which is a different door prep from the FB457's metal door installation.
6) What flush bolt do I use if the inactive leaf needs to be locked and unlocked with a key?
The Adams Rite 1870 Series cylinder-operated flushbolt adds key control, and the Adams Rite 1877 is the cylinder-operated flushbolt built for paired wood doors. Both are operated by a cylinder rather than by a lever at the door edge, which is what you want when the inactive leaf must be under key control by a facility keying scheme. The Ives FB457 is a manual bolt with no cylinder, thrown by hand at the door edge, and is intended for metal door applications where the round bolt head only needs a punched hole in the frame.
7) What is the closest equivalent to the Ives FB457 flush bolt for a metal double door?
The ABH 1855S is the nearest single manual flush bolt for metal doors, and it shares the 3/4 inch throw the FB457 uses. Both are manual bolts driven by hand at the door edge rather than automatic bolts released by the active leaf. The FB457 is non-handed and carries a 12 inch rod measured from the center of the bolt body to the tip, with a 1/2 inch diameter bolt tip and 7/8 inch vertical adjustment, so if you are matching an existing rod length you will want to confirm the rod on the 1855S against the opening. For fire-rated openings, the FB457 is UL Listed for 3 hours with top and bottom bolts used together.
8) I need bolts that release automatically when the active leaf opens instead of by hand - what should I use?
The ABH 1860P/1862P automatic flush bolt pair is the automatic alternative. It is fire rated 3-hour with a thermal lock and comes as a pair for the top and bottom of the inactive leaf, so the bolts retract when the active door opens rather than being thrown by hand at the edge. The Ives FB457 is a manual bolt, thrown and retracted by the installer or occupant at the door edge, and is also UL Listed for 3 hours when top and bottom bolts are used together. Choose the automatic pair where the inactive leaf must free itself on egress; choose the manual FB457 where the inactive leaf stays secured until someone deliberately releases it.
9) Do I have to order a left hand and right hand FB457, or is it non-handed?
Non-handed. The same FB457 goes on a left hand or right hand inactive leaf, so a property manager stocking spares for a building only carries one part rather than two.
10) I need to replace a flush bolt on a metal door pair but only the bottom one failed. Can I buy a single FB457?
Yes, the FB457 is sold as an individual bolt, so you can replace just the failed one. Two cautions on a fire rated opening: the UL 3 hour listing applies when top and bottom bolts are both in place, and mixing a new FB457 with an existing bolt of another make changes the assembly. If both need replacing, ABH also offers the 1854 Series manual flush bolt set with fire bolt for metal doors as a matched pair.
11) Will the FB457 hold up in a hospital or school corridor pair that gets constant use?
The bolt is brass substrate, certified to ANSI/BHMA A156.16 as a commercial product, and rated by UL for 3 hour fire openings with top and bottom bolts. Where it struggles is traffic on the inactive leaf itself: a manual bolt has to be thrown and released by hand each time. In a corridor where both leaves open all day, an automatic or two-point flushbolt such as the Adams Rite MS2180 Series auto-release two-point flushbolt is a better fit for the duty cycle.
12) How does the International Door Closers FB-1202 compare to the Ives FB457 on throw and backset?
The IDC FB-1202 is a flush bolt with a positive U joint actuator, a 5/8 inch throw, 1/8 inch offset with 7/8 inch backset, square end, with guide. The Ives FB457 has a 3/4 inch throw with a 3/4 inch bolt backset and a 1/2 inch diameter bolt tip, and its guide design with a flat-sided bolt tip prevents the bolt from rotating in service. The throw and backset figures differ between the two, so check them against your strike depth and the existing door prep before substituting one for the other.
13) I only need to replace the bottom bolt on a fire door - what are my options?
The ABH 1858 is a universal bottom fire bolt with manual operation, sold as a bottom unit. The ABH 1854 Series is a manual flush bolt set with fire bolt for metal doors, which covers both positions in one set. The Ives FB457 is UL Listed for 3 hours and its listing is conditioned on top and bottom bolts being used together on a fire rated opening, so whichever route you take, the opening needs both positions filled to stay compliant.
14) What is a two-point flushbolt and when would I use one instead of the FB457?
The Adams Rite MS1880/MS1881 are two-point flushbolts with an interlock mechanism, and the MS2180 Series is an auto-release two-point flushbolt with a Smartlock mechanism. A two-point unit drives the top and bottom bolts from a single operation rather than requiring each to be thrown separately, and the MS2180's auto-release means the bolts free themselves rather than needing manual retraction. The Ives FB457 is a single manual bolt, non-handed, thrown at the door edge, so a full opening uses one at the head and one at the sill.
15) What finishes does the Ives FB457 12 inch flush bolt come in?
Nine finishes, so you can match the rest of the hardware on the opening: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. Satin chrome (626) is the usual commercial default and matte black (622) matches current dark hardware packages.
16) What is the exact Ives part number for a 12 inch flush bolt in satin chrome?
The base model is FB457 and the 12 inch satin chrome (626) version orders as FB457 12 US26D. The finish suffix changes per finish, for example FB457 12 BLK for 622 matte black and FB457 12 US3 for 605 bright brass. The 12 in the number is the rod length in inches.
17) Which flush bolt should I standardize on across a facility with mixed finishes?
The Ives FB457 in the 12 inch rod length is offered across a broad finish range including 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome, 626 Satin Chrome, and 643E Aged Bronze, which lets one part number and one door prep carry across openings with different trim. It is non-handed, so there is no left or right stocking decision. If the standard needs to extend to paired wood doors, the Delaney 7 inch mortise extension in flush bolt and the Adams Rite 1877 for paired wood doors cover that construction.
18) Are decorative residential flush bolts an alternative to the Ives FB457 on a commercial opening?
The Emtek Flush Bolts and the Orca Hardware 6 inch flush bolt with radius corners are flush bolts, but they are a different proposition from the Ives FB457, which is a commercial unit meeting ANSI/BHMA A156.16 with L04261 certification and UL Listed for 3 hours on fire rated openings when top and bottom bolts are used together. If the opening is fire rated or has to meet a commercial specification, that certification is the deciding factor rather than the bolt profile.
