Deltana FPG6 6" Surface Bolt with Off-Set, Heavy-Duty

Surface mounted. The FPG6 screws to the face of the door, no mortising and no through-boring, which is why it's the common retrofit on a door that already has a lock and just needs a second point of security. You do need a strike or a drilled hole in the frame, sill, or header for the rod to land in.

Deltana rates the FPG6 as heavy-duty and classes it commercial, so it's built for a commercial opening rather than a light interior door. It's a manual slide bolt though, with no keyed or auto-locking function. If your spec calls for a bolt that locks with a key, the Ives SB1630 is a keyed locking surface bolt; if you want one that latches on its own, the ABH HD1805 is auto-locking with a 3/4 inch stainless bar.

That's the standard use for one. A surface bolt like the 6 inch Deltana FPG6 pins the inactive leaf to the head or the sill so the active leaf has something solid to latch into. On a pair you normally want two, one top and one bottom. Because the FPG6 is offset, it's the right pick when the strike point isn't in the same plane as the door face you're screwing it to, which is common on outward-opening pairs. Note it's a manual bolt with no fire rating, so on a labeled pair of doors you need a fire rated bolt such as the Ives SB1600 instead.

For a keyed or self-locking bolt, look at two others. The Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, so a key controls whether the bolt can be thrown or released. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, which holds itself in position without a key. The Deltana FPG6 is a manually operated solid brass bolt with an offset, meant to add security at an outward-opening door while other locks are not in use. Where the requirement is key control or an auto-lock bar, the SB1630 or HD1805 answer it.

For a labeled opening, look at the Ives fire rated bolts instead. The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and carries a fire rating, and the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security carrying a 3-hour UL listing. The Deltana FPG6 is a solid brass heavy-duty bolt with an offset, made for outside-opening doors that need extra security while other locks are not in use, and that is where it belongs. When the door is fire rated, the labeled Ives bolts are the ones to specify.

The Ives SB1640 is the brass one that carries a fire rating - it is a fire rated brass construction surface bolt with a 1 inch throw. That is a meaningfully shorter throw than what a 6 inch rod bolt like the Deltana FPG6 gives you, so it is sized for a jamb or header strike rather than a long floor reach. For an institutional buyer who has to keep brass trim on a labeled opening, the SB1640 is the one that answers both the finish and the label; the FPG6 answers the offset outside-opening condition in solid brass.

Step up to the Ives SB360 in the 12 inch length - it is a heavy-duty steel surface bolt with a 1-1/4 inch throw, and the 12 inch bar gives you twice the reach of the Deltana FPG6's 6 inch rod. That matters on tall openings, transom conditions, or where the mounting point sits well away from the header or floor strike. The FPG6 stays the choice when 6 inches of rod lands the bolt where it needs to go and you want solid brass with the offset for an outward-swinging door.

Oil rubbed bronze is the finish on the FPG6 offset bolt. It's a living finish over solid brass, so it darkens and wears at the touch points over time, which is worth knowing if you're matching it to other oil rubbed bronze hardware installed at a different date. If you need a bright or satin brass to match existing trim, Emtek's 8511 is another 6 inch solid brass surface bolt and Delaney's solid brass surface bolt is a third.

Material and intent. The FPG6 is solid brass, offset, and finished for a door where the hardware is seen. The Ives SB1600 is heavy duty steel and fire rated with a 3-1/2 inch throw, which is a utility bolt for a labeled or back-of-house opening. Pick the brass one where finish match matters and the door isn't labeled; pick the steel one where the rating or the longer throw drives the spec. Trimco's 4800 Series is another surface bolt line to look at on the commercial side.

They are both solid brass surface bolts, so they read as interchangeable on a takeoff, but they are not the same part. The Deltana FPG6 is a heavy-duty bolt with an offset and a 6 inch rod, and that offset is specifically what makes it work on an outside-opening door. The Delaney Solid Brass Surface Bolt is a straight solid brass surface bolt, and Delaney also builds the BV7600 as a decorative solid brass surface bolt for openings where the visible trim is the driver. If a drawing calls for the offset geometry, substituting a straight Delaney bolt will leave the bolt short of the strike.

Material follows the opening. The Deltana FPG6 is solid brass and comes in oil rubbed bronze, which suits a door where the bolt is seen alongside other brass trim. The Ives SB1600, SB1630, and SB360 are heavy duty steel bolts, and the ABH HD1805 uses a stainless steel bar - those are the direction to go on back-of-house, service, and utility doors where appearance is secondary to the bar itself. The FPG6 remains the brass answer, and it is the one that carries the offset for outward-opening doors.

Sold each. One FPG6 bolt per unit, so if you're doing top and bottom on an inactive leaf you're ordering two, and a building's worth of openings multiplies from there.

If the door swings in and the bolt is mostly there for looks and light duty, the Delaney BV7600 decorative solid brass surface bolt covers that, and the Delaney Solid Brass Surface Bolt is the plain version of the same idea. The Deltana FPG6 is built heavy-duty with an offset and a 6 inch rod for outside-opening doors that need real added security while other locks are not in use. On a simple inswing where neither the offset nor the heavier build is doing any work, the Delaney bolts are the straightforward choice.
