Ives IVE-SB453US26D-8-TB – Frequently Asked Questions

1) How far does the Ives SB453 bolt throw, and will it reach an existing strike?
Throw is 1-3/16 inches. That is measured from the bolt guide to the tip of the extended bolt, so the strike has to sit within that distance of the bolt housing once the bolt is mounted on the door face. The bolt bar itself is 3/4 inch wide and 1/4 inch thick, and the supplied door strike is 1-1/2 x 1-1/2 x 3/16 inches. If the strike already in your frame or threshold has a hole that takes a 3/4 x 1/4 inch bar and sits within the 1-3/16 inch reach, the SB453 drops into it. If the existing hole is a round mortise cut for a different bolt profile, use the strikes that come in the box instead of fighting the old prep.
2) What strikes and screws come with the Ives SB453, and what else do I need to buy to install it?
Both strikes are in the box: a universal top strike and a mortise bottom strike, plus wood screws and machine screws to cover either a hollow metal or a wood application. The strike supplied measures 1-1/2 x 1-1/2 x 3/16 inches. What you supply is the labor and the prep. The top strike surface mounts to the frame or the head; the bottom strike is a mortise type, so the floor, threshold, or sill has to be drilled and the strike set flush. Nothing else is required to complete a standard installation.
3) How does a surface bolt like the Ives SB453 hold a pair of doors closed?
It secures the inactive leaf. The SB453 mounts flat on the face of the inactive door, one bolt at the head and one at the sill, so that leaf is pinned top and bottom and becomes the strike surface for the active leaf. Both strikes ship with it, universal at the top and mortise at the bottom. Because it is thrown by hand from the face it is mounted on, it goes on the leaf people do not walk through, not on the active egress leaf.
4) Can a decorative solid brass surface bolt be used on a fire rated door in place of the Ives SB453?
Hardware going onto a rated opening has to be listed for that assembly. The Ives SB453 8 inch is UL listed for 3 hour fire doors up to 10 feet and is built in heavy duty steel to ANSI A156.16 L84161, which is what makes it the bolt for the rated door. The Delaney Decorative Solid Brass Surface Bolt and the Delaney Solid Brass Surface Bolt are brass-bodied decorative bolts, and they belong on the non-rated openings in the same building where the look drives the choice. Matching the appearance across both is still possible, since the SB453 is offered in 632 bright brass and 633 satin brass among its finishes.
5) The stile on my door will not take an 8 inch surface bolt - what is a shorter option?
The Emtek 8511 is a solid brass surface bolt in 6 inches, which is the shorter body when an 8 inch bolt runs past the rail or crowds a light. For reference on the layout you are replacing, the Ives SB453 body is 8 inches tall, 3/4 inch wide and 1/4 inch thick, throws 1-3/16 inches, and lands on a 1-1/2 by 1-1/2 by 3/16 inch strike. Measure the flat run of stile or rail above the bolt before choosing, and note that the SB453 8 inch is the one carrying the UL listing for 3 hour fire doors up to 10 feet if the opening is rated.
6) What is the closest ABH equivalent to the Ives SB453 8 inch surface bolt?
ABH's counterpart in the same heavy duty class is the HD1805, a heavy duty surface bolt built around a 3/4 inch stainless steel bar that locks automatically when thrown. The Ives SB453 is a heavy duty steel surface bolt measuring 3/4 inch wide by 1/4 inch thick by 8 inches tall, with a 1-3/16 inch throw and tension springs that hold the bolt in position against creep. The operating difference is the mechanism: the ABH HD1805 auto-locks, while the SB453 is set by hand and held by spring tension. The SB453 also carries ANSI A156.16 L84161 and is UL listed for 3 hour fire doors up to 10 feet, so on a rated assembly it is the one to specify.
7) How much does the Ives SB453 stick out from the door face?
The bolt body is 1/4 inch thick, 3/4 inch wide, and 8 inches tall, so it sits about a quarter inch proud of the door face plus the head of the bolt knob. That thin a profile matters on a pair where the astragal, weatherstrip, or the frame stop runs close to the leaf. Measure the clear face you have between the door edge and any applied stop before you lay it out.
8) Does the Ives SB453 meet ANSI/BHMA requirements for a commercial spec?
It carries ANSI/BHMA A156.16 L84161, the auxiliary hardware standard, with the L84161 designation identifying it as a surface bolt tested to that spec. Duty level is heavy duty and the material is steel, which is what an institutional spec normally calls for over a decorative brass bolt. If your drawing lists auxiliary hardware by A156.16 designation, this is the number to put against it.
9) What finishes does the Ives SB453 8 inch surface bolt come in? I need it to match the rest of my door hardware.
Nine finishes, and the codes are the standard BHMA numbers so they cross-reference to whatever is already hanging on your other openings: 604 clear zinc, 631 matte black, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze oil-rubbed, 643E aged bronze, 646 satin nickel, and 652 satin chrome. For a building already standardized on 652, that is the same satin chrome family as most commercial lever and closer trim. 604 clear zinc is the utility choice for back-of-house and warehouse doors where appearance is not the driver.
10) Can the Ives SB453 surface bolt be keyed or locked from the other side of the door?
No. The SB453 is a manually operated bolt with no cylinder and no keyway. It is thrown and retracted by hand from the face it is mounted on, which means access is controlled by whoever can reach that side of the leaf. If you need key control on the inactive leaf, a bolt is the wrong device for it and you want a locking device with a cylinder instead.
11) Should I use a surface bolt or a flush bolt on the inactive leaf?
A surface bolt like the SB453 mounts on the face of the door with screws, so there is no mortising of the door edge and it can be added to an existing leaf without machining. That makes it the retrofit answer and the answer on doors you cannot cut. A flush bolt is let into the edge of the door and disappears when retracted, so it is what you specify when the bolt cannot be visible or cannot project from the face. For a rated opening, note that the SB453 is UL listed for 3-hour fire doors up to 10 feet, so choosing the surface type does not cost you the rating.
12) What other surface bolts can I buy besides the Ives SB453, and how are they different?
Four other lines sit alongside it. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so it latches itself rather than being pushed home. The Trimco 4800 Series is the other commercial line. On the decorative side, the Emtek 8511 is a 6 inch solid brass bolt and Delaney offers both a plain solid brass surface bolt and a decorative version. The SB453 is the steel, heavy duty, fire-rated one, UL listed for 3-hour doors up to 10 feet, with an 8 inch bolt and a 1-3/16 inch throw. Pick on the opening: rated commercial pairs point to the Ives, a brass entry door in a residence points to the Emtek or Delaney.
13) Our spec calls out a Trimco 4800 Series surface bolt - what is the Ives cross-reference?
Trimco's surface bolt line is the 4800 Series. The Ives bolt to put against it is the SB453 in 8 inch: heavy duty steel, 3/4 inch wide by 1/4 inch thick by 8 inches tall, 1-3/16 inch throw, meeting ANSI A156.16 L84161 and UL listed for 3 hour fire doors up to 10 feet. It ships with both a universal top strike and a mortise bottom strike plus wood screws and machine screws, so the same part covers most field conditions. Check the submittal for the called-out length, throw and strike prep before substituting, since a series callout can cover several bolt lengths.
14) We are changing out surface bolts across a building where some doors are fire rated and some are not - can one bolt cover both?
The Ives SB453 8 inch can carry the whole building if you want a single part number: it is heavy duty steel, UL listed for 3 hour fire doors up to 10 feet and built to ANSI A156.16 L84161, and it comes in nine finishes - 604 clear zinc, 631 matte black, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze oil-rubbed, 643E aged bronze, 646 satin nickel and 652 satin chrome - so the rated and non-rated doors can look identical. If certain openings call for a solid brass body instead, the Delaney Solid Brass Surface Bolt and the Emtek 8511 in 6 inch cover those, and the SB453 stays on the rated assemblies.
