Deltana FPG24 24" Surface Bolt with Off-Set, Heavy-Duty

The offset on the FPG24 lets the bolt mount on an outward-opening door, where the rod has to step over from the door face to reach the strike. Deltana builds its offset surface bolts for exactly that condition, as a secondary security point used when the other locks on the door are not engaged. It is a surface-mounted bolt, so no mortising of the door is needed.

The rod measures 24 inches. That length is meant for tall openings or for the top of a door where the bolt has to be operated from a reachable height and still throw into a head strike, and it is also used at the bottom of a door where the lever sits within reach and the rod runs down to the threshold. If you only need a short local bolt at handle height, a 6 inch bolt such as the Emtek 8511 is the sort of thing to look at instead.

No mortising of the door face. The FPG24 is surface mounted, so it fastens to the face of the door and the rod drops into a strike or a hole in the frame, head, or threshold. You do have to prep the receiving point, and because this is the offset version the strike sits off the plane of the door face rather than in line with it.

The Deltana FPG24 is a 24 inch solid brass surface bolt with an off-set, heavy-duty design for surface mounting. It is described as a security bolt for outside opening doors rather than as a fire-rated device. If the opening requires a fire rating, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw that is fire rated, and the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw carrying a 3-hour UL listing. The SB1640 is a fire rated brass surface bolt with a 1 inch throw if brass construction is preferred on a rated opening.

The Deltana FPG24 has a 24 inch rod, which suits tall doors where the bolt must reach well up or down the leaf. For a much shorter run, 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. Both keep a surface-applied installation while taking up far less of the door face.

Solid brass throughout, both material and substrate. On an exterior outward-opening door that matters, because brass does not rust the way a plated steel bolt will once the plating is scratched by the rod cycling. If you want steel instead, the Ives SB1600 and SB360 are heavy duty steel surface bolts.

Oil rubbed bronze. That is the single finish offered on the FPG24, so if the rest of the door hardware on the opening is polished brass or satin nickel, this bolt will not match it.

Commercial. It is classed as a heavy-duty bolt, which is what you want on a door that gets cycled by tenants or staff rather than an occasional interior door. Property managers standardizing a building on one bolt can run the FPG24 across outward-opening exterior doors, keeping in mind it comes only in oil rubbed bronze.

The Deltana FPG24 is solid brass and surface mounted, offered in Oil Rubbed Bronze. Delaney offers a Solid Brass Surface Bolt and a Decorative Solid Brass Surface Bolt in the same material family, and the Emtek 8511 is a solid brass surface bolt in a 6 inch size. The distinction is length and styling: the FPG24 runs a 24 inch off-set rod built as heavy-duty, while those brass alternatives are shorter, more decorative bolts.

Short-throw bolts are the common mismatch. The Ives SB1630 and SB1640 each throw 1 inch and the SB360 throws 1-1/4 inch, so they are designed to engage a strike right at the head or sill rather than to run a long rod up the door face the way the 24 inch off-set FPG24 does. The ABH HD1805 also differs in operation, using an auto-locking 3/4 inch stainless steel bar instead of a manually thrown brass rod. Confirm rod length and throw against the opening before swapping.

The Deltana FPG24 is classed for commercial use as a heavy-duty off-set surface bolt in solid brass at 24 inches. For facilities standardizing across many openings, the Trimco 4800 Series surface bolts and the ABH HD1805 Series are both catalog series rather than single sizes, and Ives offers heavy duty steel bolts including the SB1600 and SB360. Steel bodies suit high-traffic service doors, while the FPG24 brass rod is the choice where finish appearance matters on the door face.

Each. The price you see is for one bolt, so a door that needs a bolt top and bottom takes two.
