Rockwood 2805 Self Latching Top Only Flush Bolt

The 2805 is a self latching top bolt. It engages on its own when the inactive leaf swings shut, so the leaf stays latched at the head with no manual step. To release it, you press the plunger button on the face of the bolt. That is the practical difference from a manual flush bolt like the Ives FB358 or the Trimco 3999, where somebody has to physically throw and retract the rod every time the inactive leaf is opened. On a pair that gets opened for deliveries or furniture a few times a week, self latching is what keeps the inactive leaf from being left unsecured.

No. The 2805 is built for metal doors, and that is the only door material it is made to go into. For a pair of wood doors you want a bolt prepped for wood, such as the Ives FB41 automatic flush bolt set for wood doors or the Ives FB42 top automatic flush bolt for wood doors. Putting a metal door bolt into a wood leaf means the mortise pocket and reinforcement do not line up.

Top only. The 2805 gives you one self latching bolt for the head of the inactive leaf, nothing for the threshold. If the opening needs the inactive leaf held at the sill too, you order a bottom bolt separately. The ABH 1858 universal bottom fire bolt is a bottom-only unit, and the ABH 1854 Series is a full manual flush bolt set with fire bolt for metal doors if you would rather buy top and bottom together.

The bolt body measures 1 x 6-3/4 inches, so that is the face dimension the edge prep has to accept on the inactive leaf. If your existing pocket was cut for a 6 inch bolt, such as a Trimco 3999SE or an Orca 86SQ, the 2805 face plate is longer and the mortise needs to be extended.

The 2805 is certified to ANSI A156.3, Type 27, and it is UL listed. It is a commercial grade product, which is what a spec writer or facility procurement group is looking for on institutional, healthcare, education, or multi-family openings.

The Rockwood 2805 is a top only flush bolt, so a second part is needed at the sill if the opening calls for two point securing. The ABH 1858 is a universal bottom fire bolt in the 1858 Series with manual operation. For a metal door pair where both ends are wanted from one set instead, the ABH 1860P/1862P is an automatic flush bolt pair, fire rated 3 hour with a thermal lock, and the ABH 1854 Series is a manual flush bolt set with fire bolt for metal doors.

The Rockwood 2805 self latching top only flush bolt is built for metal doors, so on a pair of wood doors the Ives FB42 top automatic flush bolt for wood doors is the part that does the same job at the head. The FB42 is a top automatic flush bolt for wood doors with an auxiliary fire latch. If the opening needs both top and bottom automatic bolts on wood, the Ives FB41 automatic flush bolt set for wood doors carries a 3/4 inch throw and a 90 minute fire rating.

The Rockwood 2805 engages automatically when the inactive door closes, and the inactive leaf stays latched at the top until the plunger button on the bolt face is pressed to release it. The Ives FB358 is a manual flush bolt with a 3/4 inch throw and a 1/2 inch bolt diameter, so the bolt is thrown and withdrawn by hand at the bolt every time the inactive leaf is used. Choose by how often the inactive leaf gets opened: automatic operation suits leaves that move regularly, manual suits leaves that stay closed.

Two finishes: 626 satin chrome and 630 satin stainless steel. If the levers and hinges on the rest of the openings are 626, order the 626 bolt and it reads the same. On stainless door and frame packages, 630 is the match. Those are the two standard commercial satin finishes, so on a fleet of doors you are almost always matching one or the other.

No, fasteners come with it: 8 each #8 x 3/4 inch flat head combo screws are included in the box. Nothing else ships with the bolt, so if the opening also needs a bottom bolt or a dust proof strike at the threshold, those are separate line items.

Depends on who you want operating the inactive leaf. A self latching bolt like the Rockwood 2805 re-secures itself every time the leaf closes and is released by hand at the bolt face, so anyone can open the leaf. A cylinder operated flushbolt, like the Adams Rite 1870 Series or the 1877 for paired wood doors, takes a key to move the bolt, which locks the inactive leaf down to whoever holds the key. Use the keyed version where you do not want staff or the public opening the second leaf at all. Use self latching where the leaf gets opened routinely and you just want it latched again afterward without anyone thinking about it.

That is the common reason to change. A manual bolt such as the Ives FB457, which uses a 12 inch rod on metal doors, only stays thrown if someone throws it. The 2805 latches the inactive leaf on its own each time it closes on a metal door pair. It is not a drop-in for every existing prep, though: the 2805 face is 1 x 6-3/4 inches, so check that against the pocket already cut in the door edge before you pull the old bolt.

They are not interchangeable. The Rockwood 2805 is a self latching top only flush bolt that engages on its own as the inactive door closes and releases by a plunger button on the face. 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 in a square end, both manually operated corner mount bolts. A corner mount bolt also preps differently in the door than the 1 inch by 6-3/4 inch face plate of the 2805, so swapping one for the other on an existing opening means new prep.

The Rockwood 2805 is released by pressing a plunger button on the bolt face, which is an inside release with no key control. Where the inactive leaf must be under 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. Both put operation of the bolt behind a cylinder rather than a face button.

The Rockwood 2805 is a top only bolt that self latches at the head as the inactive door closes. Where a single mechanism should drive both points, 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. Those tie the head and sill bolts to one operation, where the 2805 addresses the top of the leaf only.

They serve different openings. The Rockwood 2805 is a commercial flush bolt built to ANSI A156.3, Type 27 and is UL listed. The Delaney 7 inch slide type mortise in flush bolt, the Delaney 6 inch square end solid brass flush bolt, and the Delaney 7 inch mortise extension in flush bolt are slide and mortise style bolts operated by hand. For institutional, office, educational, hotel and detention work the 2805 is the commercial specification part; the Delaney bolts suit lighter duty paired door use.

Where the inactive leaf stays closed and no automatic engagement is wanted, the ABH 1855S is a manual flush bolt single for metal doors with a 3/4 inch throw, and the Ives FB457 is a manual flush bolt with a 12 inch rod length for metal doors and carries a fire rating. The International Door Closers FB-1202 is a flush bolt with a positive U joint actuator, 5/8 inch throw, 1/8 inch offset with 7/8 inch backset, square end, with guide. Each of those is thrown by hand rather than latching itself as the door closes.

Brass and stainless steel construction, certified to ANSI A156.3, Type 27, and rated commercial. That combination is what puts it in schools, hospitals, hotels, offices, retail, and detention work rather than residential use. Stainless in the 630 finish is the usual pick where the pair sees weather or wash down.

The Rockwood 2805 is supplied in 626 satin chrome and 630 satin stainless steel, described in the US equivalents US26D and US32D, in brass and stainless steel. Among comparable bolts, the Orca Hardware 6 inch flush bolt with radius corners in the 86SQ Series and the Delaney 6 inch square end solid brass flush bolt are the closest in face size for keeping a door pair visually consistent. Confirm the specific finish code on the substitute against the rest of the hardware on the opening.
