Cal-Royal FBG6 -US26 – Frequently Asked Questions

1) What does a flush bolt like the Cal-Royal FBG6 actually do on a pair of doors?
A flush bolt mortises into the edge of the inactive leaf of a double door and throws a bolt into the frame head or the threshold, holding that leaf shut so the active leaf has something to latch against. The FBG6 is a single route bolt, so it is one bolt, one location. A standard pair gets two: one at the top, one at the bottom of the inactive leaf. It is manually operated, so someone flips the lever by hand to release the inactive leaf, which is what you want on a leaf that stays closed day to day and only opens to move furniture or equipment through.
2) How many Cal-Royal FBG6 flush bolts do I need to order for one pair of doors?
Two per pair of doors in most cases. The FBG6 is sold as a single route bolt, not a top-and-bottom set, so you order one for the head and one for the sill of the inactive leaf. Each one ships with its own strike and 2 sets of screws, so two bolts covers the hardware for the whole inactive leaf.
3) Is the Cal-Royal FBG6 a direct replacement for an IVES #260 flush bolt?
The FBG6 is built to the same form and function as the IVES #260, at 7 inches, which is why it is used as a like-for-like swap on existing openings as well as on new work. Pull the old bolt and check the mortise pocket in the door edge before you commit; if the existing pocket was cut for a 7 inch bolt you are matching what is already there.
4) Do I need to cut into the door for a Cal-Royal FBG6, or does it surface mount?
It mortises in. The FBG6 is a 7 inch flush bolt, meaning the body is routed into the edge of the inactive leaf so the faceplate sits flush with the door edge and nothing protrudes into the gap between leaves. Budget a 7 inch pocket in the door edge plus the strike prep in the frame head or the floor. If you need something that screws onto the face of the door with no routing, a flush bolt is the wrong part type.
5) Can I use the Cal-Royal FBG6 on a fire rated pair of doors?
Do not spec the FBG6 for a fire rated opening. A fire rated pair needs a flush bolt carrying a stated fire rating, and for that ZenSupply stocks the Ives FB358 manual flush bolt and the ABH 1858 universal bottom fire bolt, along with the ABH 1860P/1862P automatic pair rated 3 hour with a thermal lock. On wood fire doors the Ives FB41 automatic set carries a 90 minute rating and the Ives FB42 top automatic bolt includes an auxiliary fire latch. Use the FBG6 on non rated commercial openings where you want a solid brass bolt in an architectural finish.
6) Should I use a manual flush bolt like the FBG6 or an automatic flush bolt on my double doors?
Manual is right when the inactive leaf stays shut and only opens occasionally: the FBG6 is operated by hand, so whoever needs the second leaf walks over and throws it. Automatic bolts retract the inactive leaf on their own when the active leaf closes, which is what you want when the second leaf gets used constantly or when an egress code path will not allow a leaf a user has to unbolt by hand. For automatic on wood doors ZenSupply carries the Ives FB41 set; for a fire rated automatic pair, the ABH 1860P/1862P. If you want key control over the inactive leaf instead, the Adams Rite 1870 Series is cylinder operated, and the 1877 is the cylinder operated version for paired wood doors.
7) My existing flush bolt pocket is 6 inches, not 7. What flush bolt fits that?
A 7 inch FBG6 will not drop into a 6 inch mortise without recutting the door edge. For a 6 inch pocket, ZenSupply stocks the Delaney 6 inch square end solid brass flush bolt, the Trimco 3999 at 6 inches with a rounded end, the Trimco 3999SE at 6 inches with a square end, and the Orca Hardware 6 inch flush bolt with radius corners. Match the end shape too, since the FBG6 is a round end bolt and a square end faceplate will leave a visible mismatch in a round cut pocket.
8) What is the closest equivalent to the Cal-Royal FBG6 flush bolt in a rounded-end corner mount?
The Trimco 3999 is a 6 inch corner mount flushbolt with a rounded end, which puts it in the same round-end family as the 7 inch Cal-Royal FBG6. The FBG6 is a single route flush bolt in solid brass and ships with a strike and two sets of screws. If the door prep already accepts a 6 inch face plate rather than a 7 inch one, the Trimco 3999 is the round-end match; if the existing mortise is cut for 7 inches, stay with the FBG6 length.
9) I need a flush bolt that a key can release from outside - is the Cal-Royal FBG6 that?
No. The Cal-Royal FBG6 is a single route flush bolt thrown by hand at the door edge. 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. Cylinder-operated bolts let the inactive leaf be released without opening the active leaf, which is what egress-controlled and after-hours pairs usually call for.
10) What is included with a Cal-Royal FBG6 flush bolt, and what do I still have to buy?
Each FBG6 comes packed with a strike and 2 sets of screws, individually poly bagged. That covers the bolt, the frame or floor strike it throws into, and the fasteners for both. What is not in the box is anything for the second location on the leaf (order a second bolt for that) and any dust proof strike or floor prep if your bottom bolt drops into a finished floor rather than a frame.
11) What finishes does the Cal-Royal FBG6 flush bolt come in?
Seven finishes, all on the solid brass body: US3 polished brass, US5 antique brass, US10B antique bronze oiled, US15 satin nickel, US15A satin nickel oxidized, US26 polished chrome, and 26D satin chrome. If you are matching hinges and lever trim already on the opening, pick off the US number stamped on that existing hardware rather than by eye, since US15 and 26D read very similarly at a distance.
12) Is there another 7 inch flush bolt that works the same way as the Cal-Royal FBG6?
The Delaney 7 inch slide type mortise in flush bolt is the closest match on length and mounting style, and Delaney also makes a 7 inch mortise extension flush bolt if you need extra reach at the head. The difference to check is the end shape: the FBG6 has a round end faceplate, so on a retrofit into an existing round cut pocket it is the one that matches without touching the door edge.
13) Can I standardize the same flush bolt across every double door in my building?
The FBG6 works for that if your openings are consistent: one model, one 7 inch prep, and seven finishes to match whatever trim is already on each floor. Two things break the standardization. Any fire rated pair needs a bolt with a stated fire rating instead, such as the Ives FB358 or the ABH 1858 bottom fire bolt. And any opening already cut for a 6 inch bolt will need the door edge recut or a 6 inch model like the Trimco 3999. Walk the openings and sort them by existing pocket length before you place a bulk order.
14) What is the difference between the Cal-Royal FBG6 and an automatic flush bolt?
The Cal-Royal FBG6 is a single route flush bolt operated by hand at the door edge. An automatic flush bolt throws and retracts with the door itself: the Ives FB41 is an automatic flush bolt set for wood doors with a 3/4 inch throw, the Ives FB42 is a top automatic flush bolt for wood doors, and the ABH 1860P/1862P is an automatic flush bolt pair. Manual bolts like the FBG6 suit an inactive leaf that stays secured; automatic bolts suit a pair where both leaves are used in daily traffic.
15) What secures both the top and bottom of an inactive leaf with one operation instead of two separate flush bolts?
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 throw head and sill in one action. The Cal-Royal FBG6 is a single route flush bolt, so a pair of them is used - one at the head and one at the sill - each operated separately at the door edge.
16) Which flush bolts are made for hollow metal doors rather than the Cal-Royal FBG6?
For metal doors, the ABH 1855S is a manual flush bolt single with a 3/4 inch throw for metal doors, the ABH 1854 series is a manual flush bolt set with fire bolt for metal doors, and the Ives FB457 is a manual flush bolt with a 12 inch rod length for metal doors. The Cal-Royal FBG6 is a 7 inch solid brass single route flush bolt for commercial door applications. Rod length matters on metal doors because the top bolt must reach the frame head above the door prep.
17) How does the Cal-Royal FBG6 compare with the International Door Closers FB-1202 flush bolt?
The International Door Closers FB-1202 is a positive U joint actuator flush bolt with a 5/8 inch throw, 1/8 inch offset, 7/8 inch backset, square end, supplied with a guide. The Cal-Royal FBG6 is a single route flush bolt with a round end in solid brass, 7 inch, packed with a strike and two sets of screws. The two differ at the face plate - square end against round end - and in what ships in the box, a guide with the FB-1202 versus a strike with the FBG6.
18) Is a bottom fire bolt the same thing as the Cal-Royal FBG6?
No, and they are not interchangeable. The ABH 1858 is a universal bottom fire bolt with manual operation, a device intended for the sill position on a rated pair. The Cal-Royal FBG6 is a solid brass single route flush bolt for commercial doors and is used where a standard manual edge bolt is called for. Ordering a fire bolt into a non-rated opening, or a standard flush bolt into a rated one, changes what the assembly is approved to do.
19) Is the Orca 86SQ flush bolt a substitute for the Cal-Royal FBG6?
The Orca Hardware 86SQ is a 6 inch flush bolt with radius corners, so the face plate reads close to the round end Cal-Royal FBG6 but the body is 6 inches against the FBG6 at 7 inches. On a replacement, the shorter plate will not cover a 7 inch mortise pocket, so it substitutes cleanly only on new prep or on an opening already cut for a 6 inch bolt.
20) Will a solid brass flush bolt hold up in a high traffic commercial building?
Solid brass is the substrate on the FBG6, and it is specified as commercial rather than residential hardware. Brass gives you a bolt that will not rust in a damp stairwell, entry vestibule, or exterior service opening, which is where a plated steel bolt starts seizing. It is used in offices, schools, healthcare, retail, warehouses, multi tenant residential, and municipal buildings. Where the bolt sees constant daily cycling rather than occasional use, an automatic bolt is usually the better call, since a manual bolt gets left unthrown.
21) What flush bolt matches decorative brass hardware on a residential-style door pair?
The Cal-Royal FBG6 is solid brass and comes in US3 polished brass and US5 antique brass along with US10B antique bronze oiled, US15 satin nickel, US15A satin nickel oxidized, US26 polished chrome and 26D satin chrome. Emtek flush bolts and the Delaney 4108 6 inch square end solid brass flush bolt are the other brass-bodied options in the group. The FBG6 keeps the round end profile; the Delaney 4108 is square end at 6 inches.
