Rockwood 2945 US26D – Frequently Asked Questions
1) Do I have to order a left hand and right hand version of the Rockwood 2945?
No handing to specify. The 2945 bottom bolt is non-handed, so one part number covers the inactive leaf whichever way the pair swings. You order by finish only.
2) Is the Rockwood 2945 acceptable on a fire rated pair of wood doors?
The 2945 is intended for labeled wood doors in the B, C, D and E range, and it carries a thermal lock that automatically locks the inactive door under the high heat of a fire, so the leaf stays secured even if the automatic mechanism is compromised. It is built to ANSI A156.3, Type 27. Match the bolt to the label on the door you actually have before you commit.
3) What do I need to order along with the Rockwood 2945 flush bolts to finish the job?
For the floor, the 2945 is set up to use the Rockwood No. 570 dust proof strike, which keeps grit out of the floor socket so the bottom bolt keeps dropping cleanly. Fasteners come in the box, so you are not sourcing screws: the top bolt ships with 4 #8 x 3/4 inch FH combo screws, 2 #8-32 x 1/2 inch FH machine screws and 3 #10 x 1 inch FH wood screws, and the bottom bolt adds 10 #8 x 3/4 inch combo screws, 4 #8-32 x 1/2 inch machine screws, 6 #10 x 1 inch wood screws and 2 #6-8 plastic anchors. The top bolt needs no plastic anchor.
4) My floor is out of level and the bottom flush bolt does not reach the strike. Can the Rockwood 2945 be adjusted?
There is adjustment built in: the bolt head rod on the 2945 adjusts up to 3/8 inch, which covers the usual undercut and floor variation on a wood pair. If something blocks the bolt head from entering the strike, the override feature lets the mechanism give rather than tearing up the door or the bolt.
5) I only need the top bolt on a pair of wood doors, not a full set. What can I use instead of the Rockwood 2945?
The Ives FB42 top automatic flush bolt for wood doors covers the top of the inactive leaf on its own and includes an auxiliary fire latch. The Rockwood 2945 is the combination set, where the bottom bolt hardware ships only with the 2945 and is what adds the fully automatic bottom bolt and the plastic anchors. If the bottom of the leaf is already handled by a strike or a surface bolt, the FB42 addresses just the top.
6) The doors are hollow metal, not wood. What flush bolt should I order instead of the Rockwood 2945?
The Rockwood 2945 is a combination flush bolt set built for wood doors. For metal doors, the ABH 1860P/1862P automatic flush bolt pair is fire rated 3 hour and carries a thermal lock, which is the same behavior the 2945 uses to lock the inactive door under high heat from fire. The ABH 1854 series is a manual flush bolt set with fire bolt for metal doors, and the ABH 1855S is a single manual flush bolt for metal doors with a 3/4 inch throw if you need only one leg of the opening.
7) Can a keyed flushbolt replace the Rockwood 2945 on a pair of wood doors?
They solve different problems. The Adams Rite 1877 is a cylinder-operated flushbolt for paired wood doors, and the Adams Rite 1870 series is a cylinder-operated flushbolt with key control, both of which put the inactive leaf under a key so it cannot be released without one. The Rockwood 2945 is released by pressing the plunger button on the bolt face, with no cylinder in the picture. Choose the cylinder-operated units when the inactive leaf must be secured against release by hand, and the 2945 when the leaf should latch and unlatch with normal use of the active door.
8) Should I use automatic flush bolts or manual flush bolts on my pair of doors?
Automatic bolts like the Rockwood 2945 release the inactive leaf when the active door opens, so a person can get the full opening without any extra step. That matters where staff move carts or furniture through daily and would otherwise leave the inactive leaf bolted forever. Manual flush bolts, such as the Ives FB358 or the Trimco 3999 corner mount, are thrown and retracted by hand and are the choice where the inactive leaf is meant to stay fixed and only be opened deliberately. Cylinder operated flushbolts like the Adams Rite 1877 for paired wood doors add key control, so only a keyholder can release the inactive leaf.
9) What finishes does the Rockwood 2945 flush bolt set come in, and will it match the rest of my door hardware?
Three finishes ship on the 2945: 626 satin chrome, 630 satin stainless steel and 10BE dark satin bronze. Satin chrome and satin stainless are the two that sit alongside most commercial lever and exit hardware in a school or office, and 10BE is the dark oil rubbed look for hospitality and higher end interiors. The bolts themselves are brass and stainless steel.
10) Is the Rockwood 2945 flush bolt set rated for commercial traffic or is it a residential part?
Commercial. The 2945 is built to the ANSI A156.3 Type 27 auxiliary door hardware standard and Rockwood hardware of this line goes into institutional buildings, offices, retail, schools, detention, sports facilities, hotels and restaurants. For a light residential pair of French doors, a solid brass surface flush bolt such as the Delaney 6 inch square end is the simpler route.
11) I only need the top flush bolt, not a pair. Does the Rockwood 2945 come as a single?
The 2945 is sold as a combination set, top bolt plus bottom bolt, and several features are called out as bottom bolt only under that number. If you need a single, a top automatic bolt for wood doors is the Ives FB42, and the ABH 1858 is a universal bottom fire bolt in manual operation.
12) Can I standardize the Rockwood 2945 across every pair of wood doors in my building?
For a facility standard it works well: the bottom bolt is non-handed so one part number fits every inactive leaf regardless of swing, the set covers labeled wood doors up to 4 by 8 feet, and it is specified to ANSI A156.3 Type 27 so it reads consistently on a hardware schedule. Pick one finish across the fleet, 626 satin chrome or 630 satin stainless being the usual institutional choices. Openings with hollow metal pairs need a different bolt.
13) What is a simpler manual alternative to the Rockwood 2945 automatic flush bolt set?
The Ives FB358 manual flush bolt has a 3/4 inch throw and a 1/2 inch bolt diameter and is fire rated. Manual bolts are thrown and retracted by hand at the bolt face, while the Rockwood 2945 top bolt engages by itself as the inactive door closes and the bottom bolt retracts as the active door opens. On an opening where the inactive leaf is set once and left alone, a manual bolt does the job; where the inactive leaf is worked daily, the automatic action of the 2945 is what removes the manual step.
14) Is a 6 inch mortise flush bolt the same thing as the Rockwood 2945?
No. Items such as the Delaney 6 inch square end solid brass flush bolt, the Delaney 7 inch slide type mortise in flush bolt, the Trimco 3999 6 inch corner mount rounded end flushbolt and the Trimco 3999SE square end version are single mortised bolts operated by hand at the bolt face. The Rockwood 2945 is a combination set covering both the top and bottom of the inactive leaf, non-handed, with an override feature that prevents damage to the door or bolt if the bolt head is blocked from entering the strike. If the opening needs automatic latching of the inactive leaf, a single manual mortise bolt is not a substitute.
15) Which flush bolt meets ANSI A156.3 Type 27 for a pair of wood doors?
The Rockwood 2945 combination flush bolt set is a commercial product built to ANSI A156.3, Type 27, in brass and stainless steel. Among automatic sets for the same kind of opening, the Ives FB41 automatic flush bolt set for wood doors is fire rated 90 minutes and the Ives FB42 top automatic flush bolt for wood doors carries an auxiliary fire latch. Where a specification calls out Type 27 by number, the 2945 answers it directly.
16) I need a longer rod at the top of a metal door opening. What flush bolt covers that instead of the Rockwood 2945?
The Ives FB457 manual flush bolt has a 12 inch rod length, is made for metal doors and is fire rated. The Rockwood 2945 is a wood door set whose bolt head rod is adjustable up to 3/8 inch, which trims for strike alignment rather than reaching farther up the leaf. For a taller top rod on a hollow metal opening, the FB457 is the part that addresses it.
17) What is the difference between the Rockwood 2945 and a two-point flushbolt like the Adams Rite MS2180?
The Adams Rite MS2180 series is an auto-release two-point flushbolt with a Smartlock mechanism, and the MS1880/MS1881 are two-point flushbolts with an interlock mechanism, both operating the top and bottom points through a single linked mechanism. The Rockwood 2945 is a combination set for wood doors with an automatically engaging top bolt and a fully automatic bottom bolt, and it is non-handed. The two-point Adams Rite units are the route when the opening calls for a linked interlock or auto-release; the 2945 is the route for a conventional pair of wood doors latching off the active leaf.
18) I only need to replace the bottom fire bolt on a pair of doors. Do I have to buy a full set?
The ABH 1858 is a universal bottom fire bolt of manual operation, sold to address the bottom of the leaf on its own. The Rockwood 2945 is the full combination set, with the bottom bolt hardware supplied on the 2945 only and a thermal lock that automatically locks the inactive door under high heat conditions due to fire. If the top of the opening is intact and only the bottom bolt is being replaced, the 1858 is the single-position part.
19) Do I need to match handing when ordering the Rockwood 2945 or a comparable flush bolt?
The Rockwood 2945 bottom bolt is non-handed, so one part number covers either leaf orientation and there is no left or right to specify when ordering. It is available in 626 satin chrome, 630 satin stainless steel and 10BE dark satin bronze. Comparable automatic sets for the same kind of opening include the Ives FB41 for wood doors with a 3/4 inch throw and the ABH 1860P/1862P automatic pair for metal doors.
20) What flush bolt should I use if the extension rod needs to reach past a standard mortise pocket on a wood door?
The Delaney 7 inch mortise extension flush bolt is built as an extension-style mortise bolt for that reach, and the Delaney 7 inch slide type mortise in flush bolt is the slide-operated version. The Rockwood 2945 is an automatic combination set whose bolt head rod is adjustable up to 3/8 inch for strike alignment. The Delaney units are hand-operated single bolts, so the inactive leaf is set and released manually rather than latching off the movement of the active door.
