Deltana 6FBS 6" Flush Bolt, Heavy-Duty, Stainless Steel

The Deltana 6FBS holds the inactive leaf of a double door shut so the active leaf has something to latch against. It mortises into the edge of the inactive door and throws a 1 inch bolt into a strike in the head frame or the floor. You operate it by hand at the door edge, so the inactive leaf stays fixed until someone deliberately retracts it.

Manual. The 6FBS is thrown and retracted by hand at the door edge, which means the inactive leaf stays bolted until a person releases it. If you need the inactive leaf to release automatically when the active leaf opens, look at an automatic set instead, such as the Ives FB41 automatic flush bolt set for wood doors or the ABH 1860P/1862P automatic pair.

Each 6FBS is packed as a single bolt with its #6 x 3/4 inch screws, sold by the each. A typical inactive leaf gets two, one at the top into the frame head and one at the bottom into the floor, so order two per pair of doors. Bulk quantities run 15 pieces per box and 75 per case.

The 6FBS throws 1 inch, which is longer than many competing manual bolts, so it will reach into a standard frame head strike or floor strike with room to spare. By comparison the Ives FB358 manual bolt throws 3/4 inch and the International Door Closers FB-1202 throws 5/8 inch. If you are reusing strikes drilled for a shorter bolt, the extra length is not a problem at the head, but check floor depth so the bolt bottoms out in the strike rather than on the slab.

The 6FBS has a 6 inch faceplate, which is the most common size on existing pairs, so it lines up with an existing 6 inch mortise in most cases. Other 6 inch options that share the same faceplate length include the Trimco 3999 with a rounded end, the Trimco 3999SE square end, and the Orca 6 inch bolt with radius corners, so match the end shape of what is coming out. If the existing bolt is 7 inches, the Delaney 7 inch mortise flush bolt is the size match instead.

The Deltana 6FBS is a heavy-duty manual flush bolt for holding the inactive leaf of a double door in a recessed install, described as a commercial-duty part. For an opening where a fire-rated bolt is called for, the fire-rated options include the ABH 1854 series manual flush bolt set supplied with a fire bolt for metal doors, the ABH 1858 universal bottom fire bolt, the ABH 1860P/1862P automatic flush bolt pair rated 3-hour with a thermal lock, the Ives FB358 manual flush bolt, the Ives FB41 automatic set for wood doors rated 90 minutes, and the Ives FB42 top automatic bolt for wood doors with an auxiliary fire latch. Choose by door material and by whether the opening requires manual or automatic operation.

The Deltana 6FBS is a 6-inch manual flush bolt in stainless steel with a 1-inch throw. Comparable 6-inch manual flush bolts include the Orca Hardware 86SQ series 6-inch flush bolt with radius corners, the Trimco 3999 6-inch corner mount flush bolt with a rounded end, the Trimco 3999SE 6-inch corner mount with a square end, and the Delaney 4108 6-inch square end solid brass flush bolt. The Deltana and Delaney differ in base material - stainless steel versus solid brass - and the Trimco pair differ from each other only in end shape, so match the end profile and mounting style to the mortise already cut in the door.

The Deltana 6FBS is manually operated by hand at the bolt face. When the inactive leaf has to be locked or released with a key, the cylinder-operated options are the Adams Rite 1870 series flushbolt with key control and the Adams Rite 1877 cylinder-operated flushbolt for paired wood doors. For two-point locking of the leaf, the Adams Rite MS1880/MS1881 two-point flushbolts use an interlock mechanism and the MS2180 series is an auto-release two-point flushbolt with the Smartlock mechanism. These require cylinder prep and deeper door machining than a recessed manual bolt.

No - it looks similar in the door but works differently. The Deltana 6FBS is a manual bolt: someone has to throw and retract it by hand on the inactive leaf. Automatic bolts such as the ABH 1860P/1862P automatic flush bolt pair and the Ives FB41 automatic flush bolt set for wood doors retract when the active leaf opens, which is what an opening requiring unobstructed egress typically calls for. The Ives FB42 is only the top bolt of such a set for wood doors, not a complete pair. Confirm whether your opening was specified for manual or automatic operation before swapping.

It is built for commercial use and specified heavy-duty, with a stainless steel body and bolt rather than plated brass. Stainless also suits exterior or damp openings where a brass or plated bolt would discolor. For a decorative interior pair in a residential setting, a solid brass bolt such as the Delaney 6 inch square end brass flush bolt is the closer match on appearance.

It is a recessed (mortised) bolt. The faceplate sits flush in the edge of the inactive leaf, so you route a pocket for the case and a shallow mortise for the 6 inch faceplate. That keeps the bolt out of the way when the pair is closed, but it does mean the door edge has to be prepped, not just drilled.

The 6FBS is released by hand at the door edge, so anyone standing at the open pair can drop the inactive leaf. A cylinder operated flushbolt is keyed, which stops that. If you need key control over the inactive leaf, the Adams Rite 1870 Series is the cylinder operated version for that job, and the 1877 is the cylinder operated flushbolt for paired wood doors.

Yes, each bolt ships with #6 x 3/4 inch screws for the faceplate. Strikes are the separate item to account for: plan on a head strike for the top bolt and a floor strike or dust proof strike for the bottom, since those are not part of the packed bolt.

The Deltana 6FBS 6-inch flush bolt throws 1 inch. Among the manual alternatives, the ABH 1855S single manual flush bolt for metal doors and the Ives FB358 both throw 3/4 inch, and the International Door Closers FB-1202 throws 5/8 inch with a 1/8 inch offset and 7/8 inch backset. If the strike or floor condition needs the bolt to reach further into the prep, the Deltana 6FBS carries the longest stated throw of that group.

The Deltana 6FBS has a 6-inch face plate. For a 7-inch mortise pocket, 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. If the opening needs the bolt rod to reach much further, the Ives FB457 manual flush bolt is offered with a 12-inch rod for metal doors. Measure the existing pocket length and edge prep before ordering, since face plate length is what has to match.

The Deltana 6FBS is a stainless steel heavy-duty flush bolt for recessed installation in a double door. Where the leaf is hollow metal, the bolts specifically described for metal doors are the ABH 1854 series manual set with fire bolt, the ABH 1855S single manual bolt, and the Ives FB457 with a 12-inch rod. On the wood side, the Ives FB41 automatic set, the Ives FB42 top automatic bolt, and the Adams Rite 1877 cylinder-operated flushbolt are described for paired wood doors. Door construction drives the edge prep, so match it to the leaf you are cutting.

Brushed stainless is the finish on the 6FBS, which is the natural match for stainless pulls, push plates and hinges on a commercial opening. Because the bolt is solid stainless rather than plated, the face will not flake or wear through to a different color at the thumbpiece.

The Deltana 6FBS is stainless steel in a brushed stainless finish, which is a common choice for standardizing across commercial double-door openings. Where the existing door trim is brass, the Delaney 4108 6-inch square end flush bolt is solid brass at the same 6-inch length, and Emtek also offers flush bolts as a decorative line. Function is the same recessed manual bolt in each case, so the decision comes down to base material and the finish family already on the doors.
