Ives IVE-SB1600M1-B-SP28 – Frequently Asked Questions

1) I have a big undercut at the bottom of my door. Will a surface bolt still reach a floor strike?
That is what the extra travel on the Ives SB1600 is for. It throws 3-1/2 inches, so it covers openings where a standard-throw bolt runs out of bolt before it ever reaches the floor. Order it with the B (bottom strike) or BL (bottom locking strike) option so the strike comes with it, and measure from the bolt's rest position down to where the strike will sit before you commit, since 3-1/2 inches is the limit of the travel, not a starting point.
2) Is the Ives SB1600 surface bolt allowed on a fire-rated pair of doors?
The SB1600 is UL Listed for 3 hour fire doors up to 8 feet and it meets ANSI A156.16 L84161, so it is the right class of auxiliary hardware for a rated commercial opening rather than a residential-grade bolt pressed into service. The listing is what your inspector will want cited, and it is printed on the product data as UL Listed for 3 Hour fire doors, up to 8 ft.
3) What is the difference between the Ives SB1600 M1 and M2, and which one do I order?
Only the actuator tab direction. M1 has the tab pointing away from the door, M2 has it pointing toward the door. Everything else is the same part: same steel body, same 3-1/2 inch throw, same four strike choices, same five finishes. Ives catalogs them as SB1600M1 and SB1600M2. Pick by which way the tab needs to face so it is comfortable to reach and clears whatever else is on the face of that leaf.
4) The Ives SB1600 lists T, TL, B and BL strikes. What do I have to specify?
Two decisions. First, where the bolt lands: T is a top strike and B is a bottom strike. Second, whether you want it keyed: TL and BL are the locking versions, and the locking bolt secures in both the up and the down position and comes with 2 keys in 4 keying variations, so a bolt left retracted cannot be thrown by anyone without the key either. The strike that ships with it measures 1-1/4 x 7/8 x 15/16 inches, so check that footprint against the flat you have at the frame head or the threshold.
5) What is the closest heavy duty equivalent to the Ives SB1600 surface bolt?
The nearest heavy duty peer is the ABH HD1805, a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar. The Ives SB1600 is a steel surface bolt with an 11 inch by 3/4 inch by 3/4 inch body and a 3-1/2 inch throw engineered for doors with larger undercuts, UL Listed for 3-hour fire doors up to 8 ft and meeting ANSI A156.16 L84161. The working difference is the bar material and how each one holds: the HD1805 auto-locks with a stainless steel bar, while the SB1600 uses a steel bar and offers a locking strike version that secures in both the up and down positions, furnished with two keys in four keying variations.
6) We are replacing surface bolts on a fire-rated pair of doors - can I substitute any surface bolt of the same size?
Match the fire requirement before the size. The Ives SB1600 is UL Listed for 3-hour fire doors up to 8 ft and meets ANSI A156.16 L84161, which is the standard a rated pair gets inspected against, and it is a commercial heavy duty steel bolt. The other surface bolts in the same size class are built around different priorities: the Emtek 8511 is a 6 inch solid brass surface bolt, the Delaney BV7600 is a decorative solid brass surface bolt, and the ABH HD1805 is a heavy duty bolt with an auto-locking 3/4 inch stainless steel bar. On a rated opening, verify the bolt's listing covers the door assembly before it goes on the door.
7) Do I have to mortise the door to install an Ives SB1600 surface bolt?
No routing into the door edge. The SB1600 is a surface bolt, so the steel body screws to the face of the leaf and the strike mounts at the head or the threshold. Both wood screws and machine screws are packed with each unit, which covers a wood leaf and a metal-prepped one out of the same box. That is what makes it a workable fix on a pair that was never prepped for flush bolts, since the door itself does not have to be machined.
8) Will the Ives SB1600 fit on a narrow stile aluminum storefront door?
Lay the numbers on the stile before you order. The SB1600 body measures 11 x 3/4 x 3/4 inches, so two of the three dimensions are 3/4 inch and only one is long; you need that long run of flat face plus 3/4 inch across it, clear of the glass stop and any pull. It is offered in 628 clear anodized aluminum, which is the finish that matches most aluminum storefront work.
9) I need surface bolts to match dark bronze doors across a building. What finishes does the Ives SB1600 come in?
Five: 622 matte black, 628 clear anodized aluminum, 691 bronze painted, 695 dark bronze, and 706 brass painted. Every one of those five is offered with all four strike styles and in both the M1 and M2 versions, so you can standardize a building on one finish even though individual openings need different strikes or a different tab direction.
10) Is there a stainless steel surface bolt instead of a painted steel one?
The Ives SB1600 body is steel, offered in painted and anodized finishes rather than stainless. If a stainless bar is what the job calls for, ZenSupply carries the ABH HD1805 heavy duty surface bolt, which uses a 3/4 inch stainless steel bar and locks automatically. The operating difference matters: the ABH is auto-locking, while the Ives locking versions (TL and BL strikes) hold the bolt with a key in either the up or down position.
11) What's a better surface bolt for a decorative or residential opening than a heavy commercial one?
The SB1600 is a commercial, heavy duty steel bolt built around a fire listing, which is more hardware than a decorative interior pair usually needs. For solid brass, ZenSupply carries the Emtek 8511 solid brass surface bolt in 6 inch, plus Delaney's solid brass surface bolt and its decorative solid brass version. Those are brass rather than steel, so they suit a finish-driven opening. On a rated door, stay with the Ives and its UL listing.
12) I want a surface bolt in solid brass instead of steel - what are my options?
Two solid brass surface bolts sit alongside the steel Ives SB1600: the Delaney 410309 Solid Brass Surface Bolt and the Emtek 8511 Solid Brass Surface Bolt in 6 inch. Both are brass-bodied, where the SB1600 is a steel bolt with an 11 inch by 3/4 inch by 3/4 inch body, a 3-1/2 inch throw, and a strike measuring 1-1/4 inch by 7/8 inch by 15/16 inch. Brass changes the look and the corrosion behavior; steel with a 3-1/2 inch throw is what suits doors with larger undercuts and commercial traffic.
13) Which surface bolt should I use where the hardware is visible and has to look finished rather than utilitarian?
The Delaney BV7600 is a decorative solid brass surface bolt, made for openings where the bolt is part of the visible hardware package, and the Delaney 410309 is the plain solid brass version of the same idea. The Ives SB1600 takes the opposite approach: it is a heavy duty steel bolt with fully concealed mounting to prevent tampering, offered in matte black, clear anodized aluminum, dark bronze, bronze painted, and brass painted finishes. If the decision is driven by appearance on a front-of-house door, the brass Delaney bolts are the direct comparison; if it is driven by security on a commercial pair, the concealed-mount steel bolt is.
14) I need a surface bolt that stays locked without someone keying it - how does that compare to the Ives SB1600?
The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so the bar itself holds position without a separate keyed step. The Ives SB1600 handles this through the strike: it ships in top, top locking, bottom, and bottom locking strike versions, and the locking version secures in both the up and down positions and comes with two keys in four keying variations, so a facility can control who releases the bolt. Choose on who is meant to operate it - the auto-locking bar for hands-off holding, the keyed locking strike where the bolt has to stay set until an authorized person releases it.
15) Can someone tamper with the mounting screws on the Ives SB1600 once it's installed?
Mounting on the SB1600 is fully concealed, so there are no exposed fasteners to back out once it is up. Body is steel, rated heavy duty for commercial use, and it meets ANSI A156.16 L84161. On an opening where you also want the bolt itself controlled, the TL and BL locking strike options key the bolt in both the up and down position.
16) What other commercial surface bolts could I spec besides the Ives SB1600?
Trimco's 4800 Series surface bolts and the ABH HD1805 are the commercial-duty peers ZenSupply stocks alongside the Ives. Where the SB1600 lands is on its own numbers: 3-1/2 inch throw for doors with large undercuts, UL Listed for 3 hour fire doors up to 8 feet, ANSI A156.16 L84161, steel body with fully concealed mounting, and four strike styles including keyed locking versions. Hold whatever you are considering against those four points and the choice usually makes itself.
17) We are standardizing surface bolts across a portfolio of buildings - which line covers the most openings?
Two of the options are full series rather than single items: the Ives SB1600 in its M1 and M2 versions, and the Trimco 4800 Series surface bolts. The SB1600 spans M1 with the actuator tab pointing away from the door and M2 with the tab pointing toward the door, four strike types including top, top locking, bottom, and bottom locking, and five finishes, all on one heavy duty steel platform meeting ANSI A156.16 L84161 and UL Listed for 3-hour fire doors up to 8 ft. That combination lets rated and non-rated openings across a portfolio carry the same bolt with only the version, strike, and finish changing.
