Ives SB1640T US3 – Frequently Asked Questions

1) Do I need two Ives SB1640 surface bolts to secure the inactive leaf of a pair of doors?
To bolt the inactive leaf at both the head and the floor, order two. The SB1640T comes with a top strike and the SB1640B comes with a bottom strike, so a single unit only covers one end of the leaf. Plenty of openings get just the top bolt into the frame head, with the lock or exit device holding the bottom. Order both units in the same finish code so the pair matches: 605 bright brass, 613 satin bronze oil-rubbed, or 626 satin chrome.
2) How far does the Ives SB1640 bolt throw, and does a strike come with it?
One inch of throw, and the matching strike is included with every unit: T versions ship with the top strike, B versions with the bottom strike. The strike itself measures 1-1/4 x 7/8 x 15/16 inches, so that is the footprint to allow for on the frame head or the floor. The bolt body measures 8 x 7/8 x 3/4 inches. With a full 1 inch of projection there is room for the normal gap between leaf and frame and still real engagement in the strike.
3) Can the ABH HD1805 be used in place of the Ives SB1640 surface bolt?
Both are surface bolts for an inactive leaf, but they are built to different requirements. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so the bar locks itself when it is thrown. The Ives SB1640 is a brass surface bolt measuring 8 by 7/8 by 3/4 inches with a 1 inch throw and a 1-1/4 by 7/8 by 15/16 inch door strike, UL Listed for 3 hour fire doors up to 8 feet and meeting ANSI A156.16 L24161. Specify the SB1640 when the pair is a rated assembly and the submittal calls out A156.16 L24161; specify the HD1805 when the requirement is a stainless bar that locks on its own. The two mount with different screw patterns and different strikes, so treat a change between them as new door prep rather than a drop-in.
4) What do I have to specify when ordering an Ives SB1640, and is it handed?
No handing to call out. Three things get specified: strike position (T for top, B for bottom), whether you want the plain bolt or the locking version (BL and TL add a locking bolt), and one of three finishes, 605 bright brass, 613 satin bronze oil-rubbed, or 626 satin chrome. That is twelve orderable combinations in total, and the option letter is part of the model number, as in SB1640TL US26D.
5) What is the difference between the Ives SB1640B and the SB1640BL surface bolt?
The L is the locking option. SB1640B is the standard surface bolt with a bottom strike, thrown and retracted by hand; SB1640BL is the same bolt with a bottom strike plus a locking bolt, so the thrown position can be secured rather than simply left shot. The same pairing exists at the head: SB1640T against SB1640TL. Both versions come in all three finishes.
6) Surface bolt or flush bolt for an inactive leaf, which one do I want?
A surface bolt like the Ives SB1640 mounts on the face of the door and throws into a supplied strike, so the door edge never gets mortised. The whole unit is 8 x 7/8 x 3/4 inches sitting proud of the leaf. A flush bolt is the other approach: it buries in the edge of the door, needs that edge routed and the frame or floor prepped, and disappears from view. Pick the surface bolt when you are adding security to an existing leaf and do not want to pull and machine the door, or when the door is already hung. Pick a flush bolt when the hardware has to be out of sight and out of reach.
7) Does the Ives SB1640 come with the screws to mount it on a hollow metal door as well as a wood door?
Fasteners for both are in the box. Each SB1640 is packed with wood screws and machine screws, plus an end plug and end plug stud package, so a wood leaf takes the wood screws and a hollow metal leaf takes the machine screws into tapped holes. Nothing extra to order for a standard install; the strike comes with the unit too.
8) What other commercial surface bolts could I use instead of the Ives SB1640?
Two to look at. The Trimco 4800 Series is the closest straight alternative, a commercial surface bolt line. The ABH HD1805 is a heavier duty take: an auto-locking bolt with a 3/4 inch stainless steel bar, so it locks itself when thrown rather than relying on a separate locking option the way the Ives SB1640BL and SB1640TL do. Stainless bar versus the brass substrate on the Ives is the other difference if the opening sees moisture.
9) I need a surface bolt for a decorative interior or residential door, not a commercial fire door. What should I look at?
The Ives SB1640 is a commercial bolt, sized 8 x 7/8 x 3/4 inches with a plain utility look, so it is more hardware than a nice interior door usually wants. For a decorative application, the Delaney Decorative Solid Brass Surface Bolt is built for exactly that, and the Delaney Solid Brass Surface Bolt is the simpler solid brass version. The Emtek 8511 is a 6 inch solid brass surface bolt if you want something shorter on a French or closet pair.
10) What does ANSI A156.16 L24161 mean on the Ives SB1640 spec?
A156.16 is the BHMA standard covering auxiliary door hardware, and L24161 is the type number within it that identifies this class of bolt. For a submittal or a hardware schedule that is the line you copy across: the SB1640 meets ANSI A156.16 L24161 and is UL Listed for 3 hour fire doors up to 8 ft, which is usually everything an institutional reviewer asks for on an inactive leaf bolt.
11) What is the difference between the locking version of the Ives SB1640 and the auto-locking ABH HD1805?
The locking function is chosen differently on each. The Ives SB1640 is ordered in four option codes - T for a top strike, B for a bottom strike, TL for the locking bolt with a top strike, and BL for the locking bolt with a bottom strike - so the lock and the strike position are selected together at order time on a brass bolt with a 1 inch throw. The ABH HD1805 is a heavy duty surface bolt whose 3/4 inch stainless steel bar is auto-locking as built. If the bolts are going into a rated pair, the SB1640 is the one carrying the UL listing for 3 hour fire doors up to 8 feet, and the TL or BL code gets you the locking bolt without giving that up.
12) Will an Ives SB1640 surface bolt hold up on a school or apartment corridor door where people pick at the hardware?
Built for that traffic. Brass substrate, commercial grade, and the mounting is fully concealed so there are no exposed fasteners to back out or pry at from the corridor side. It meets ANSI A156.16 L24161 and is UL Listed for 3 hour fire doors up to 8 ft, which covers most stair and corridor pairs in a school, healthcare or multi-tenant building.
13) What finishes does the Ives SB1640 surface bolt come in, and will it match my existing door hardware?
Three finishes across every option: 605 bright brass, 613 satin bronze oil-rubbed, and 626 satin chrome. Those are the standard BHMA finish codes, so 626 lines up with satin chrome levers and closers, 613 with oil-rubbed bronze trim, and 605 with polished brass. Every strike option (T, B, TL, BL) is available in all three, so a top and bottom bolt on the same leaf will match.
14) The bolt will be visible on a lobby door pair - is there a more decorative option than the Ives SB1640?
The Delaney BV7600 is a decorative solid brass surface bolt, built for openings where the bolt is meant to read as part of the visible hardware. The Ives SB1640 takes the other approach: a plain brass body 8 by 7/8 by 3/4 inches with fully concealed mounting so there is nothing exposed to tamper with, offered in 605 bright brass, 613 satin bronze oil-rubbed, and 626 satin chrome. On a lobby pair that also has to be rated, the SB1640 is the bolt that is UL Listed for 3 hour fire doors up to 8 feet, and the finish selection is how it gets matched to the surrounding trim.
