Cal-Royal UNIFB780-US1 – Frequently Asked Questions

1) What is the difference between the self-latching top bolt and the auto flush bottom bolt in the UNIFB780 set?
They do two different jobs on the same inactive leaf. The top bolt is self-latching, so it engages into the frame head on its own as the leaf closes. The bottom bolt is an automatic flush bolt, which engages into the floor strike automatically as well. Both are supplied together in one coordinated set, so you are not buying a top and bottom bolt separately and hoping they work together. The top bolt head is square, the bottom is round, so keep them straight during install.
2) Do I still need a manual flush bolt if I install automatic flush bolts on a pair of doors?
No, and that is the point of the UNIFB780. Manual flush bolts have to be thrown by hand every time, which is why they get left open in high traffic. The UNIFB780 pair engages automatically as the inactive leaf closes, so the leaf stays secured without anyone reaching up. If you actually want the leaf held manually and released only when someone chooses, a manual set like the ABH 1855S single or the Ives FB358 is the other approach.
3) Is the Cal-Royal UNIFB780 flush bolt set fire rated for a labeled pair of doors?
For a labeled pair you want a set that carries the fire rating outright. The ABH 1860P/1862P automatic flush bolt pair is listed at a 3-hour fire rating with a thermal lock, and on wood pairs the Ives FB41 automatic set carries a 90 minute rating. If the opening is labeled, specify from those rather than assuming any automatic bolt will pass the inspection.
4) What is the closest equivalent to the Cal-Royal UNIFB780 flush bolt set for a pair of wood doors?
The Ives FB41 automatic flush bolt set is built for wood doors and carries a 90 minute fire rating, with a 3/4 inch throw. The UNIFB780 differs in that it is a universal set intended for both metal and wood doors, combining a self-latching top bolt with an auto flush bottom bolt in one set, built to ANSI/BHMA A156.3-2008 Type 25. If the opening is a wood pair and you want a set specified for wood only, the FB41 is the direct counterpart.
5) I need key control over the inactive leaf - is the Cal-Royal UNIFB780 the right flush bolt?
No. The UNIFB780 is a self-latching and auto flush bolt combination with a square top bolt head and a round bottom bolt head, operated by the door rather than by a key. For key control, the Adams Rite 1870 Series is a cylinder-operated flushbolt with key control, and the Adams Rite 1877 is a cylinder-operated flushbolt for paired wood doors. Those let a keyed cylinder throw and retract the bolt, which the UNIFB780 does not do.
6) What ANSI standard do the Cal-Royal UNIFB780 flush bolts meet?
The UNIFB780 set is built to ANSI/BHMA A156.3-2008, Type 25. A156.3 is the exit device and auxiliary bolt standard, and the Type 25 designation is what a spec writer or an institutional buyer will be looking for on the door hardware schedule for automatic flush bolts on a pair.
7) Do the Cal-Royal UNIFB780 flush bolts come with screws, or do I need to supply fasteners?
Fasteners are included. Each bolt component ships with #8 fasteners, so the installer is not sourcing hardware on the job. What is not in the box is the strike work: an automatic flush bolt still needs a strike in the frame head and a floor strike or threshold prep at the bottom, and the door edge has to be mortised for the face plate.
8) I need to lock the inactive leaf with a key instead of automatically. What should I use instead of an automatic flush bolt?
An automatic set like the UNIFB780 engages on its own with no key control at all. If the inactive leaf has to be released only by an authorized person, the Adams Rite 1870 Series is a cylinder-operated flushbolt with key control, and the 1877 is the cylinder-operated version for paired wood doors. For a two-point bolt with an interlock, look at the Adams Rite MS1880/MS1881.
9) Can I buy just the top or just the bottom bolt from the Cal-Royal UNIFB780?
The UNIFB780 is sold as a combination set, self-latching top plus auto flush bottom together. If you only need to replace one end, a single is the right buy instead: the ABH 1855S is a manual flush bolt single for metal doors, and the ABH 1858 is a universal bottom bolt. Mixing a single into an existing automatic pair changes how the leaf behaves, so match the operation you already have.
10) What is a simpler alternative to the Cal-Royal UNIFB780 if I do not need automatic operation?
The ABH 1855S is a manual flush bolt single for metal doors with a 3/4 inch throw, and the Ives FB358 is a manual flush bolt with a 3/4 inch throw and 1/2 inch bolt diameter that carries a fire rating. Both are operated by hand at the bolt. The Cal-Royal UNIFB780 instead pairs a self-latching top bolt with an auto flush bottom bolt so the inactive leaf engages without a separate motion. Choose manual when the inactive leaf stays fixed most of the time and staff will set it deliberately.
11) Are the 6 inch corner mount flushbolts a substitute for the Cal-Royal UNIFB780?
They are a different part despite the shared name. The Trimco 3999 is a 6 inch corner mount flushbolt with a rounded end and the Trimco 3999SE is the 6 inch corner mount square end version; the Orca Hardware 86SQ is a 6 inch flush bolt with radius corners. Those are single bolts sized and prepped by their own length. The Cal-Royal UNIFB780 is a two-piece set with a 1 x 2 inch face plate on each bolt, so the door edge prep and the count of bolts you receive are not the same.
12) What top bolt works with an auxiliary fire latch instead of the Cal-Royal UNIFB780 self-latching bolt?
The Ives FB42 is a top automatic flush bolt for wood doors with an auxiliary fire latch and carries a fire rating. The ABH 1858 is a universal bottom fire bolt of manual operation, and the ABH 1854 Series is a manual flush bolt set with a fire bolt for metal doors. The Cal-Royal UNIFB780 handles the top of the door with a self-latching bolt and the bottom with an auto flush bolt, both with a #8 fastener, and does not include a separate auxiliary fire latch component.
13) What two-point flushbolt should I look at instead of the Cal-Royal UNIFB780 for an aluminum storefront pair?
The Adams Rite MS1880/MS1881 are two-point flushbolts with an interlock mechanism, and the Adams Rite MS2180 Series is an auto-release two-point flushbolt with a Smartlock mechanism. Both drive top and bottom from a single point on the inactive leaf. The Cal-Royal UNIFB780 is a universal set for metal and wood doors with independent self-latching top and auto flush bottom bolts, each on a 1 x 2 inch face plate.
14) Which flush bolt has a shorter throw than the Cal-Royal UNIFB780 for a shallow strike condition?
The International Door Closers FB-1202 uses a positive U joint actuator with a 5/8 inch throw, a 1/8 inch offset and a 7/8 inch backset, square end, with a guide. The ABH 1855S and the Ives FB358 both run a 3/4 inch throw. Confirm the head and threshold conditions against the throw before committing, since the FB-1202 also fixes the backset at 7/8 inch.
15) Is a mortise slide bolt the same thing as the Cal-Royal UNIFB780?
No. The Delaney 4101 is a 7 inch slide type mortise-in flush bolt, the Delaney 4363 is a 7 inch mortise extension flush bolt, and the Delaney 4108 is a 6 inch square end solid brass flush bolt - each a single mortised bolt thrown by hand at a slide. The Cal-Royal UNIFB780 is a commercial set built to ANSI/BHMA A156.3-2008 Type 25 with a self-latching top bolt and an auto flush bottom bolt. If a submittal calls out Type 25 self-latching, a slide bolt does not answer it.
16) What finishes do the Cal-Royal UNIFB780 flush bolts come in?
Two: US1 flat black and US32D satin stainless steel. US32D is the standard commercial match for most hollow metal openings and lines up with satin stainless exit devices and pulls on the same pair. US1 flat black is the choice when the rest of the opening is dark bronze or black storefront hardware.
17) Are the Cal-Royal UNIFB780 flush bolts suitable for a high-traffic commercial building or are they residential grade?
Commercial. The UNIFB780 is a commercial-duty set built to the A156.3 Type 25 requirement, and the typical openings are office buildings, schools, healthcare, retail, warehouse, multi-tenant residential, and municipal buildings. For decorative residential pairs, a solid brass surface bolt such as the Delaney 6 inch square end or the Orca 6 inch radius corner flush bolt is the different animal.
18) I need a longer rod flush bolt for a tall metal door pair - what works instead of the Cal-Royal UNIFB780?
The Ives FB457 is a manual flush bolt with a 12 inch rod length for metal doors and carries a fire rating. The Cal-Royal UNIFB780 is a self-latching and auto flush bolt combination for metal and wood doors with a 1 x 2 inch face plate on each bolt. Where the top rail height or an oversized leaf calls for reach up the door edge, the 12 inch rod version is the one to price.
