Adams Rite MS1880-02-682 – Frequently Asked Questions

1) Will Adams Rite MS1880 flushbolts work on narrow stile aluminum storefront doors?
That's what the MS1880/MS1881 two-point flushbolt was built for: narrow stile aluminum doors. The mechanism body measures 1 1/2 x 6 7/8 x 1 1/4 inches, so it fits inside a narrow stile without the wide backplate a corner-mount flushbolt needs. Hollow metal and wood door versions are offered as well, so the same two-point setup can carry across an aluminum entry and interior metal or wood pairs.
2) What does the interlock on the MS1880 two-point flushbolt actually do?
It stops the pivoted deadbolt of the paired MS deadlock from entering until the vertical bolts are thrown. In practice that means an installer or user cannot lock the active leaf against an inactive leaf that isn't secured, which is the usual failure with flip-lever flushbolts on a pair. One turn of the knob 180 degrees clockwise throws both bolts, so the inactive leaf is secured top and bottom in a single motion.
3) Will the MS1880 bolts engage my existing header and threshold guides?
The bolts are hexagonal 3/8 inch stainless steel with a 23/32 inch throw. That throw is shorter than the 3/4 inch throw common on corner-mount flushbolts, and the 3/8 inch hex bolt will not seat correctly in a guide bored for a 1/2 inch round bolt. Plan on installing the supplied bolt guides in the header and threshold rather than reusing what is in the opening.
4) What cylinder do I order with an Adams Rite MS1880 flushbolt?
It takes a standard Adams Rite MS cam mortise cylinder. That's the same cylinder family used across Adams Rite MS deadlocks, so a building already standardized on Adams Rite MS can key the flushbolt into the existing system rather than carrying a second keyway.
5) What do I have to specify when ordering an MS1880 flushbolt?
Three things decide the part number. Cylinder height, in five bands: 31 to 35 inches, 35-1/16 to 39, 39-1/16 to 43, 43-1/16 to 47, and 47-1/16 to 51 inches, measured to where the cylinder sits on the door. Turn shape, hourglass or teardrop. And finish, offered as 119 Black Anodized, 121 Dark Bronze Anodized, or 682 Satin Chrome. Measure the cylinder height on the opening before ordering; it is the one value you cannot change later without a different unit.
6) My pair of doors is fire rated. Can I use the Adams Rite MS1880?
For a labeled fire door pair, specify a flush bolt carrying a stated fire rating. In the ABH 1860P/1862P automatic flush bolt pair that's a 3-hour rating with thermal lock; the Ives FB41 automatic set for wood doors is rated 90 minutes; the ABH 1854 set and the Ives FB42 top bolt include an auxiliary fire latch for that use. Match the rating on the door label, and note that most fire pairs require automatic rather than manual bolts.
7) The inactive leaf on my double door is fire rated - can I use the Adams Rite MS1880 flushbolt?
The Adams Rite MS1880/MS1881 is offered in UL Listed models, so confirm the specific model against the fire door assembly listing before ordering. Where the opening calls for a flush bolt built around fire performance, the ABH 1854 Series manual flush bolt set includes a fire bolt for metal doors, the ABH 1858 is a universal bottom fire bolt, and the ABH 1860P/1862P automatic flush bolt pair is fire rated 3-hour with a thermal lock. On wood doors, the Ives FB41 automatic flush bolt set carries a 90 minute fire rating and the Ives FB42 top automatic flush bolt for wood doors includes an auxiliary fire latch.
8) What is the difference between the Adams Rite MS1880 two-point flushbolt and a standard manual flush bolt like the Ives FB358?
The Adams Rite MS1880/MS1881 is a two-point flushbolt with an interlock mechanism: one 180-degree turn of the knob drives 3/8 inch stainless steel bolts with 23/32 inch throw into head and threshold together, and the interlock blocks the pivoted bolt of the paired MS deadlock until those vertical bolts are secured. The Ives FB358 is a manual flush bolt with 3/4 inch throw and 1/2 inch bolt diameter, thrown one bolt at a time by hand at the lever. If the requirement is one operation securing both points and sequencing with an MS deadlock, that is the MS1880; if the inactive leaf is simply pinned top and bottom independently, the FB358 covers it.
9) I do not want the tenant to have to throw the bolts at all - what is the alternative to the Adams Rite MS1880?
The Adams Rite MS1880/MS1881 still requires a deliberate action: the knob is turned 180 degrees clockwise to engage the bolts, with the interlock enforcing the order against the paired MS pivoted deadlock. For an inactive leaf that should secure itself when the doors close, look at automatic flush bolts instead - the ABH 1860P/1862P automatic flush bolt pair for fire rated openings, or on wood doors the Ives FB41 automatic flush bolt set with 3/4 inch throw and the Ives FB42 top automatic flush bolt. Automatic bolts trade the single-operation interlock sequencing for hands-free engagement.
10) My double doors are narrow stile aluminum storefront - which flush bolts actually fit?
The Adams Rite MS1880/MS1881 is specifically engineered for narrow stile aluminum doors, with hollow metal and wood door options also available, and it accepts standard Adams Rite MS cam mortise cylinders. Most of the alternatives are built around other door constructions: the ABH 1855S manual flush bolt single and the Ives FB457 with 12 inch rod length are for metal doors, the Ives FB41 automatic set and Ives FB42 top bolt are for wood doors, and the Delaney 6 inch square end solid brass flush bolt and Trimco 3999 6 inch corner mount are surface-proportioned bolts sized for conventional stiles. On a glass front aluminum leaf, the narrow stile design is the deciding factor.
11) Is a 6 inch edge-mount flush bolt an equivalent replacement for an Adams Rite MS1880?
No. The Adams Rite MS1880/MS1881 is a two-point system: a single knob operation drives both the head and threshold bolts and interlocks with the paired MS pivoted deadlock, and it is ordered to a cylinder height range from 31 inches through 51 inches. A 6 inch edge-mount bolt such as the Trimco 3999 rounded end, the Trimco 3999SE square end, the Orca Hardware 6 inch flush bolt with radius corners, or the Delaney 6 inch square end solid brass bolt is a single independent bolt at one edge of the leaf, mounted at whatever height the prep allows. Two of them will pin a leaf top and bottom, but each is thrown separately and none of them sequences with the deadlock.
12) My double doors are taller than 84 inches - what are my options for flush bolts?
The Adams Rite MS1880/MS1881 is designed for doors up to 84 inches, and the optional Tall Door Kit TDK-1880 extends it to doors up to 120 inches, so a tall opening is handled by adding the kit rather than changing product. If you are working a metal door and prefer to reach height with rod length instead, the Ives FB457 is a manual flush bolt supplied with a 12 inch rod for metal doors. Confirm the leaf height before ordering, since the MS1880 without the tall door kit stops at 84 inches.
13) Should I use a two-point flushbolt or a pair of standard manual flush bolts on an inactive leaf?
Standard flush bolts, like the Trimco 3999 6 inch corner mount or the Orca 6 inch, are two separate levers: someone has to bend down for the bottom bolt and reach up for the top. The Adams Rite MS1880 replaces both with one knob that throws top and bottom together, and adds the interlock tie to the MS deadlock. Where the inactive leaf gets opened often, or where it is a tall entrance and reaching the top lever is awkward, the two-point unit is the practical choice. Where the leaf is set once and left alone, a simple corner-mount pair does the job.
14) Can I put the MS1880 on a pair with access control?
The MS1880 works with Adams Rite electric strikes, so the active leaf can be released electrically while the inactive leaf stays bolted top and bottom by the flushbolt. The flushbolt itself is mechanical, hand-operated by the knob, so the inactive leaf still has to be released manually when both leaves need to open.
15) What is a simpler flush bolt to specify when I do not need the two-point interlock?
When the inactive leaf just needs to be held and there is no MS deadlock to sequence with, a single manual bolt is the shorter spec. The ABH 1855S is a manual flush bolt single for metal doors with 3/4 inch throw, the International Door Closers FB-1202 is a square end bolt with 5/8 inch throw, 1/8 inch offset and 7/8 inch backset supplied with a guide, and the Ives FB457 comes with a 12 inch rod length for metal doors. Each of these is thrown at its own lever rather than by the single 180 degree knob operation that drives both bolts on the Adams Rite MS1880/MS1881.
16) How does bolt throw on the Adams Rite MS1880 compare to other flush bolts, and does it change my header and threshold prep?
The Adams Rite MS1880/MS1881 throws 23/32 inch on a hexagonal 3/8 inch stainless steel bolt, and the bolt guides in the header and threshold have to be aligned for that 23/32 inch engagement. Peer bolts differ: the ABH 1855S and the Ives FB41 both list 3/4 inch throw, the Ives FB358 is 3/4 inch throw on a 1/2 inch bolt diameter, and the International Door Closers FB-1202 is 5/8 inch throw with a 7/8 inch backset. Throw and bolt diameter both drive the strike hole depth and size, so the prep is not interchangeable between these when you are retrofitting an existing header.
17) I need the flush bolt to match the anodized aluminum storefront - which one finishes correctly?
The Adams Rite MS1880/MS1881 is ordered in 119 Black Anodized, 121 Dark Bronze Anodized, and 682 Satin Chrome, and it is also offered in US3, US4, US10B, US32 and US32D, so it will pick up an anodized storefront directly. The Delaney 6 inch square end bolt is a solid brass flush bolt and the Emtek flush bolts are architectural residential trim bolts, which is a different look on an aluminum leaf. If you are standardizing an anodized entrance across a building, the anodized options on the MS1880 are the closer match.
18) Will an Adams Rite MS1880 work with my access control and electric strike, or should I pick a different flush bolt?
The Adams Rite MS1880/MS1881 is compatible with Adams Rite electric strikes for access control and accepts standard Adams Rite MS cam mortise cylinders, so it is the one in the group built to sit inside an Adams Rite MS deadlock and strike system on a commercial opening. The mechanical alternatives - the ABH 1854 and 1855S sets, the Trimco 3999 and 3999SE corner mount bolts, the Orca 6 inch bolt, and the Delaney 7 inch slide type mortise bolt - are standalone bolts that hold the inactive leaf and do not tie into a keyed MS cylinder or strike arrangement.
19) Do I need a separate bottom bolt with the Adams Rite MS1880 the way I would with a top automatic bolt?
No. The Adams Rite MS1880/MS1881 is a two-point flushbolt - one knob operation drives bolts into both the header and the threshold, with guides installed at each. Some alternatives are sold as one end of a pair and have to be completed: the Ives FB42 is a top automatic flush bolt for wood doors, and the ABH 1858 is a universal bottom fire bolt. The ABH 1860P/1862P is supplied as an automatic flush bolt pair, and the ABH 1854 is a flush bolt set. Check whether the peer you are quoting is a set or a single before you count what the job needs.
20) Which finish on the MS1880 matches my existing storefront doors?
Three anodized and plated options are offered on the flushbolt: 119 Black Anodized, 121 Dark Bronze Anodized, and 682 Satin Chrome. Dark bronze and black are the usual matches to anodized aluminum storefront; satin chrome pairs with brushed stainless or aluminum trim. All three are available in every cylinder height band and in both hourglass and teardrop turn shapes.
21) What's the difference between the Adams Rite MS1880 and MS1881?
Both are two-point flushbolts sharing the same interlock mechanism, 3/8 inch stainless bolts and 23/32 inch throw; MS1880 is the base model designation carried on the unit. Order by the model plus the cylinder height band, turn shape and finish, since those are what change the part you receive.
22) What is the difference between a mortise flush bolt and a mortise extension flush bolt from Delaney, and how do they relate to the Adams Rite MS1880?
The Delaney 4101 is a 7 inch slide type mortise in flush bolt and the Delaney 4363 is a 7 inch mortise extension in flush bolt - both mortise into the leaf edge, with the extension version adding reach beyond the bolt body itself. Both are single-point bolts operated at the leaf edge. The Adams Rite MS1880/MS1881 is a two-point system operated from a knob turned 180 degrees, which drives head and threshold bolts together and interlocks with the paired MS pivoted deadlock, so it is not a drop-in swap for either Delaney bolt prep.
