Rockwood ROC-2949-32D – Frequently Asked Questions
1) Do I have to drill the floor or set a floor strike for the Rockwood 2949?
No floor prep. The bottom fire bolt on the 2949 eliminates the need for a floor strike, which is the main reason people pick it over a conventional bottom flush bolt that has to drop into a threshold or floor mortise. The fire bolt strike hole is oversized as well, so slight door misalignment still lets the bolt seat.
2) What is the difference between a self latching flush bolt and a manual flush bolt on a pair of doors?
A manual flush bolt has to be thrown and retracted by hand every time, so the inactive leaf stays bolted until someone reaches down and lifts it. The Rockwood 2949 is self latching at the top: close the inactive leaf and the top bolt latches itself, which keeps a fire pair secured without depending on staff to do it. If you actually want the inactive leaf under deliberate manual control, ZenSupply carries manual sets like the Ives FB358 and the ABH 1855S. For key control over who can release the inactive leaf, the Adams Rite 1877 is a cylinder-operated flushbolt for paired wood doors.
3) What happens if the doors settle and the top bolt hits the frame instead of the strike?
The 2949 has an override built in, so if the bolt head is blocked from entering the strike it gives rather than damaging the door or the bolt. On top of that the bolt head rod adjusts up to 1/2 inch, so you can dial out normal frame settling or a slightly out-of-square opening at install instead of re-mortising the strike.
4) What else should I look at if my wood pair needs a longer fire rating than 20 minutes?
The 2949 carries a 20-minute UL listing on wood core and composite doors. For wood pairs where you need more, the Ives FB41 automatic flush bolt set for wood doors is rated 90 minutes, and the ABH 1860P/1862P automatic flush bolt pair is rated 3-hour with a thermal lock.
5) Is the Ives FB42 the same thing as a Rockwood 2949?
They serve the same opening but cover different amounts of it. The Ives FB42 WD is a top automatic flush bolt for wood doors with an auxiliary fire latch, meaning it is the top bolt on its own. The Rockwood 2949 is supplied as a self latching top bolt together with a bottom fire bolt, and its bottom fire bolt eliminates the need for floor prep. Confirm whether the opening needs only a top device or a top and bottom pair before ordering either.
6) What is the closest equivalent to a Rockwood 2949 automatic flush bolt for a pair of wood doors?
The Rockwood 2949 is a self latching flush bolt with a bottom fire bolt built for fire rated wood doors, so the nearest peer is the Ives FB41 automatic flush bolt set for wood doors, which carries a 90 minute fire rating and a 3/4 inch throw. Both are automatic-style sets intended for the inactive leaf of a wood door pair rather than manual bolts that an operator throws by hand.
7) What flush bolt do I use if the inactive leaf has to be keyed rather than latched automatically?
The Rockwood 2949 is a self latching bolt with no cylinder, so key control comes from a different family. 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 put operation of the inactive leaf behind a key instead of latching it when the door closes.
8) What should I use instead of a Rockwood 2949 when the inactive leaf has to release automatically as the active leaf opens?
The Rockwood 2949 latches the inactive leaf when the door closes and is released at the bolt. Where the requirement is an automatic release tied to the active leaf, the Adams Rite MS2180 Series is an auto-release two-point flushbolt with a Smartlock mechanism, and the Adams Rite MS1880/MS1881 is a two-point flushbolt with an interlock mechanism that ties the two leaves together. Both are two-point devices, so they set the top and bottom of the leaf from a single operation.
9) Is the Rockwood 2949 flush bolt handed? Do I need to order left or right?
Non-handed. One 2949 set covers either hand, so you don't specify handing on the order and you don't need to stock two versions across a building.
10) Can I use the Rockwood 2949 on a single door instead of a pair?
No. A flush bolt like the 2949 mortises into the edge of the inactive leaf of a pair and latches into the head frame, so it needs a second leaf to hold shut. On a single opening the active hardware, a lock or exit device, does that job. For a pair on which you only need to replace the bottom fire bolt, ZenSupply carries the ABH 1858 universal bottom fire bolt.
11) We do not need automatic operation, just a manual flush bolt for a wood door pair. What is simpler than a Rockwood 2949?
Where the inactive leaf is thrown by hand, a manual bolt covers it. The Ives FB358 is a manual flush bolt with a 3/4 inch throw and a 1/2 inch bolt diameter and is fire rated. The Trimco 3999 is a 6 inch corner mount flushbolt with a rounded end and the Trimco 3999SE is the same 6 inch corner mount with a square end. None of these self latch the way the Rockwood 2949 does; someone has to operate the bolt at the door.
12) I only need to replace the bottom fire bolt, not the whole set. Is there a single part for that?
Yes. The Rockwood 2949 is furnished as a top self latching bolt plus a bottom fire bolt as one set. If only the bottom device is being replaced, the ABH 1858 is a universal bottom fire bolt of manual operation sold on its own, and the ABH 1855S is a manual flush bolt single for metal doors with a 3/4 inch throw.
13) Which flush bolts look like a substitute for a Rockwood 2949 but should not be used on a fire rated opening?
Several mortise and edge-mount bolts share the flush bolt name without the fire bolt function. The Delaney 7 inch slide type mortise in flush bolt, the Delaney 6 inch square end solid brass flush bolt, the Delaney 7 inch mortise extension flush bolt, and the Orca Hardware 6 inch flush bolt with radius corners are decorative-profile edge bolts. The Rockwood 2949 is a commercial device with a bottom fire bolt and a thermal lock that automatically locks the inactive door under high heat conditions due to fire, which is what a rated wood pair is specified for.
14) Our metal door pairs use a 12 inch rod flush bolt. Does the Rockwood 2949 cross to that?
No. The Ives FB457 is a manual flush bolt with a 12 inch rod length for metal doors and is fire rated, which is a different door material and a rod-length-specific device. The Rockwood 2949 is a wood door bolt whose bolt head rod is adjustable up to 1/2 inch, so it is set at the opening rather than ordered by rod length. Standardizing a facility on one or the other means splitting by door material, not by rod dimension.
15) What flush bolt has a defined backset and offset for an edge that is already prepped?
The International Door Closers FB-1202 is a flush bolt with a positive U joint actuator, a 5/8 inch throw, a 1/8 inch offset with a 7/8 inch backset, a square end, and a guide, so the prep dimensions are stated for the device. The Rockwood 2949 works differently at the sill: its bottom fire bolt eliminates the need for floor prep and its oversize fire bolt strike hole allows for slight door misalignment.
16) Do screws come with the Rockwood 2949 flush bolt, or do I need to supply fasteners?
Fasteners are in the box: 6 each #8 x 3/4 inch flat head combo screws, 2 plastic anchors, and 3 each #10 x 1 inch flat head wood screws. Nothing extra to order to mount the bolt itself.
17) What finish does the Rockwood 2949 come in, and will it match my other stainless door hardware?
One finish only: 630 satin stainless steel, the US32D equivalent, on a stainless steel bolt. That is the standard commercial finish on most institutional pulls, push plates, and hinges, so it matches a typical satin stainless opening without a special order.
18) Is the Rockwood 2949 suitable for residential double doors, or is it a commercial part?
It's a commercial part, the kind used on institutional, office, retail, education, hotel, and detention openings. On a residential wood pair where there's no fire rating to hold, a simpler surface or mortise bolt does the job: ZenSupply carries the Delaney 6 inch square end solid brass flush bolt and the Delaney 7 inch slide type mortise-in flush bolt, plus Emtek flush bolts.
19) Is a Rockwood 2949 a match for the flush bolts on our residential-style interior door pairs?
The Rockwood 2949 is a commercial stainless steel device in US32D, furnished with 6 each #8 x 3/4 inch FH combo screws, 2 each plastic anchors and 3 each #10 x 1 inch FH wood screws. For an interior pair where appearance drives the choice, Emtek flush bolts and the Delaney 6 inch square end solid brass flush bolt are the decorative-finish options. The trade-off is function: those are hand-operated bolts, while the 2949 self latches and carries a bottom fire bolt.
