Ives IVE-261-B26D – Frequently Asked Questions

1) Will the Ives 261 flush bolt work on the inactive leaf of a pair of doors?
That's exactly what the 261 is for. It's a manual flush bolt that mortises into the edge of the inactive leaf on a pair, throwing a 3/4 inch brass bolt into the frame head or the threshold to hold that leaf fixed so the active leaf has something to latch against. The bolt is 5/16 inch diameter with a 15/32 inch backset from the door edge, and the face plate is 4 inches long. Non-handed, so the same part works on a left or right hand pair, top or bottom.
2) How deep does the door edge have to be routed for an Ives 261 flush bolt?
Plan the mortise around the 4 inch face plate length and a 1-1/8 inch depth, with the bolt sitting 15/32 inch back from the door face. That's a shallow-backset bolt, so it goes into the narrow edge of a stile without needing much meat behind it. Route the pocket, mark from the template, then drill the frame head and the sill for the 5/16 inch bolt tip.
3) Do I need one Ives 261 or two per pair of doors?
Two per inactive leaf is the normal spec: one at the top throwing into the frame head, one at the bottom throwing into the threshold or floor. The 261 is sold as a single bolt, and because it's non-handed the same part covers both positions. If you only need to hold the leaf at the head, one is enough, but a single top bolt lets the bottom of the leaf flex under load.
4) I want the inactive door leaf keyed so only staff can release it. Is the Ives 261 the right bolt?
No. The 261 is hand operated through a finger cup, so anyone who can reach it can throw or retract the bolt. For key control over the inactive leaf, look at the Adams Rite 1870 Series cylinder-operated flushbolt, or the 1877 if the pair is wood. Adams Rite also makes two-point flushbolts, the MS1880/MS1881 with an interlock and the MS2180 Series with an auto-release Smartlock mechanism, if you need both bolts driven from one point.
5) Will a 3/4 inch throw flush bolt reach my existing strike holes?
3/4 inch of projection on a 5/16 inch bolt is the common commercial throw, so the 261 drops into most existing top and bottom flush bolt preps without redrilling. Where it will not is a prep cut for a shorter bolt: the International Door Closers FB-1202, for example, throws 5/8 inch with a 7/8 inch backset, so a hole set for that bolt sits too far back from the door face for the 261's 15/32 inch backset. Measure from the door face to the existing hole center before you commit.
6) The inactive leaf needs to be released with a key from the outside - what flush bolt does that instead of a manual one?
The Ives 261 is manually operated: you extend and retract the bolt by hand at the deep cup finger hole, so it can only be worked from the side it is mounted on. For key control, the Adams Rite 1870 Series is a cylinder-operated flushbolt, and the Adams Rite 1877 is a cylinder-operated flushbolt for paired wood doors. Choose by leaf material - the 1877 is the wood door pair version - and expect to add a cylinder, which a manual 261 does not require.
7) Is an automatic flush bolt a drop-in substitute for the Ives 261?
No - they secure the inactive leaf differently. The Ives 261 is a manual bolt with a double action spring that holds the brass bolt where you put it, projected or retracted, so a person sets it. The ABH 1860P/1862P is an automatic flush bolt pair, fire rated 3-hour with a thermal lock, which throws the bolt as the doors close without anyone touching it. Swapping in an automatic pair changes the door prep and means ordering top and bottom together rather than the single bolt the 261 is.
8) What is the difference between the Ives 261 and the International Door Closers FB-1202 flush bolt?
They differ in bolt geometry. The Ives 261 has a 3/4 inch throw with a 15/32 inch backset and a 5/16 inch diameter bolt tip. The International Door Closers FB-1202 has a 5/8 inch throw, a 1/8 inch offset with a 7/8 inch backset, a square end, and comes with a guide. The backset is the number to check against the door prep already cut - 15/32 inch and 7/8 inch land the bolt in different places in the stile, so the two are not interchangeable in an existing mortise.
9) For a fire rated door pair, what fire bolt options exist alongside the Ives 261?
The Ives 261 is UL Listed for fire door applications and meets ANSI A156.16 L04201. Where the specification calls out a fire bolt by name, the ABH 1854 Series is a manual flush bolt set with a fire bolt for metal doors, and the ABH 1858 is a universal bottom fire bolt with manual operation. The 1858 is a bottom bolt specifically, so it pairs with a top bolt rather than standing in for one; the 1854 set covers both positions in one order.
10) Does the Ives 261 flush bolt stay retracted on its own, or does it drop when you open the door?
It holds where you put it. The 261 uses a double action spring that keeps the brass bolt captive in either the projected or the retracted position, so the inactive leaf won't have a bolt dragging on the sill once you pull it back. You move it with a finger in the deep cup on the face plate, no tool needed.
11) What finishes does the Ives 261 flush bolt come in?
Six, and they're the standard commercial BHMA numbers so they'll match the rest of the trim on the opening: 605 bright brass, 609 blackened brass, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, and 626 satin chrome. If you're standardizing a building, 626 satin chrome (model 261-B26D) is the usual commercial default and 605 bright brass (261-B3) matches older brass hardware sets.
12) Is the Ives 261 flush bolt solid brass or plated steel?
Cast brass, polished, all the way through the bolt itself. That matters on exterior pairs and on bottom bolts that sit near a wet threshold, where a plated steel bolt will corrode in the strike hole and seize. Brass substrate is also why the 605 and 609 brass finishes on this one wear the way brass does rather than flaking off a base metal.
13) Ives 261 vs a 6 inch flush bolt, which do I need?
Length is about the stile you're mortising into, not about strength. The 261 has a 4 inch face plate, which suits narrower stiles and shallow rails where a longer plate would run past the joinery. If you have a wide wood stile and want more plate to fasten into, the Trimco 3999 and 3999SE are 6 inch corner mount flush bolts (rounded and square end), and the Delaney 4108 is a 6 inch square end solid brass bolt. Match the end shape and length to the other bolts already in the building so the openings look consistent.
14) I need a longer mortise flush bolt for a tall wood door pair - what goes in place of the Ives 261?
The Ives 261 is a 4 inch bolt with a 15/32 inch backset and 3/4 inch throw. Where the stile is deep enough and you want more reach, the Delaney 4101 is a 7 inch slide type mortise-in flush bolt and the Delaney 4363 is a 7 inch mortise extension flush bolt. The extension version is the one to look at when the bolt has to travel farther to reach the header or threshold than a bolt of the 261 length can.
15) When would I specify a two-point flushbolt rather than the Ives 261?
The Ives 261 is a single manual bolt - you order one for the top of the inactive leaf and one for the bottom, and each is worked separately. 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 throwing top and bottom together from one operation. Two-point hardware is the choice when the inactive leaf must be secured or released in a single motion; the 261 is the choice when each bolt is set independently.
16) Is the Ives 261 flush bolt rated for commercial traffic or is it a residential part?
Commercial. It's built to ANSI A156.16 L04201, which is the auxiliary trim classification a spec writer will call out on office, school, healthcare, and government openings, and the cast brass body holds up to the cycle count those buildings put on an inactive leaf. If you're standardizing hardware across a facility, the model number to write is Ives 261 plus the BHMA finish code.

    The Ives flush bolt is a breeze to use and keeps my double doors locked tight. Love how discreet it is. Just remember, the screws could be longer for a sturdier fit. Overall, a solid security choice for my doors.
