Deltana FPG42 42" Surface Bolt with Off-Set, Heavy-Duty

The Deltana FPG42 carries a 42 inch rod, so it throws far up the door leaf rather than just a few inches past the edge. That length is aimed at tall or oversized leaves, French doors, and full-height entry doors where you want the bolt engaging well above head height into a header strike. On a standard 80 inch leaf a 42 inch rod still mounts fine, it just runs most of the way up the stile, which is usually the point: the bolt head sits within reach at the top while the strap and rod carry the load. If you need a short bolt tucked at the top or bottom edge only, a 6 inch bolt like the Emtek 8511 or the 12 inch Ives SB360 is the shape you want instead.

The offset kinks the rod away from the mounting plane so the bolt head can clear a raised panel, an astragal, or a stop that sits proud of the flat face you are screwing to. On an outswing door the bolt has to reach past the door edge geometry to drop into its strike, and a straight rod would bind on whatever is in the way. Deltana builds this one specifically for outside opening doors, so the offset is doing that clearance job. If your door face is flat all the way to the strike point, a straight surface bolt is simpler to mount.

Yes, that is the classic use. A surface bolt pins the inactive leaf to the head or the threshold so the active leaf has something solid to latch against. The FPG42 is a manual bolt, so you throw and retract it by hand from the inside face of the door, which means it works on the inactive leaf that nobody uses day to day. Deltana positions these as extra security while other locks are not in use, so it is a supplement to your main lockset, not a replacement for it. If you need the inactive leaf to release automatically when the active leaf opens, a manual surface bolt is the wrong tool and you want an automatic flush bolt instead.

Surface mounted, so no mortising of the leaf. The bolt body and rod guides screw to the face of the door and you drill the strike hole in the header, threshold, or floor. That makes it a retrofit you can do on an existing door without routing a pocket, which is why property managers and remodelers reach for surface bolts on doors that are already hung. The trade-off is that the hardware is visible on the door face, so if you want it concealed you are looking at a flush bolt mortised into the door edge, not this.

For a labeled fire door opening, specify a bolt that carries the rating on its own record. The Ives SB1630 is listed with a 3-hour UL rating and a 1 inch throw with keyed security, and the Ives SB1600 (3-1/2 inch throw) and SB1640 (1 inch throw, brass) are both carried as fire rated. Those are the ones to put on a labeled opening. The Deltana FPG42 is built as a decorative solid brass bolt for outside opening doors and extra security when other locks are not in use, so it belongs on non-labeled entry, French, and patio door applications.

The offset version, which is what the FPG42 is. Deltana builds the off-set surface bolts specifically for outside opening doors, where the rod needs to step over the door geometry to reach its strike. A straight surface bolt on an outswing leaf will often foul the stop or the astragal. Specify the offset model, then pick the finish from the nine available.

The Deltana FPG42 is a heavy-duty surface bolt built in solid brass with a 42 inch rod. If the opening calls for steel rather than brass, the ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, and the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw. The FPG42 gives you a long 42 inch rod for reaching a header or threshold from mid-door; the ABH and Ives units are shorter-throw bolts that hold at the point where they are mounted.

The Deltana FPG42 carries a 42 inch rod, which suits a tall door leaf or a door where the bolt is thrown from mid-height into the header or sill. For a short brass bolt at the top or bottom rail, the Emtek 8511 is a 6 inch solid brass surface bolt, and the Ives SB360 is a heavy-duty steel surface bolt with a 1-1/4 inch throw in a 12 inch length. Delaney also builds a solid brass surface bolt in its 410309 line.

The Deltana FPG42 is a hand-thrown offset surface bolt in solid brass, meant to add security while other locks are not in use - it has no key. If the door needs a bolt that a tenant or the public cannot simply retract, the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security. The ABH HD1805 takes a different approach with an auto-locking 3/4 inch stainless steel bar.

Solid brass, both the described material and the substrate on record. That matters on an exterior application, since a solid brass bolt and rod will not rust through the way a plated steel one can once the coating gets scratched at the guides. It also means the decorative finishes are applied over brass rather than over steel. If you want steel or stainless instead, for a higher duty commercial opening, the ABH HD1805 uses a 3/4 inch stainless steel bar and the Ives SB1600 and SB360 are steel.

Nine finishes: Polished Brass, PVD Polished Brass, Antique Brass, Polished Chrome, Brushed Chrome, Brushed Nickel, Antique Nickel, Oil Rubbed Bronze, and Paint Black. That spread covers the common Deltana trim palettes, so a bolt can be matched to the hinges, levers, and pulls already on the opening. PVD Polished Brass is the one to pick for an exterior door if you want the brass look to hold up outdoors, since PVD is a harder deposited coating than standard lacquered brass. Paint Black is the choice when the bolt needs to disappear against a dark door.

Deltana lists the FPG42 as a commercial product and builds it as a heavy-duty bolt in solid brass. It suits multi-family entries, offices, and light commercial openings where a manual bolt secures a leaf that is not in daily use. For a high-traffic institutional opening where you want steel and an auto-locking action, the ABH HD1805 with its 3/4 inch stainless steel bar is the sturdier direction, and the Trimco 4800 Series is another commercial line to look at.

Length changes what the bolt is for. Short bolts in the 6 to 12 inch range, like the Emtek 8511 at 6 inches or the Ives SB360 at 12 inches, mount right at the top or bottom edge and throw a couple of inches into a strike. The Deltana FPG42's 42 inch rod is meant to be operated from a comfortable height while the bolt engages far up the leaf, which is what you need on a tall door where a top-edge bolt would be out of reach. Same job, different geometry: pick by where you want your hand and where you want the strike.

No key on the Deltana FPG42. It is a manual throw bolt, operated by hand from the face it is mounted on, which means it secures the door only from the side it is installed. If you need a bolt that keys, the Ives SB1630 is a heavy duty locking surface bolt with keyed security and a 1 inch throw. For an unattended or public-side opening, that keyed option is the one to specify.

The FPG42 is a commercial heavy-duty offset bolt in solid brass with a 42 inch rod, offered in nine finishes including oil rubbed bronze, antique brass, polished chrome and PVD polished brass. Where the emphasis is on appearance at a short rail rather than a long throw, the Delaney BV7600 decorative solid brass surface bolt and the Emtek 8511 solid brass surface bolt at 6 inches are the brass alternatives in the set.

No. Both are solid brass surface bolts, but the Emtek 8511 is a 6 inch bolt and the Deltana FPG42 carries a 42 inch rod with an off-set, heavy-duty build. The 42 inch rod covers the distance from a mounting point on the door face down to the sill or up to the header, which a 6 inch bolt cannot do. Swap them only if the mounting point is already at the strike.
