Ives SB1630-TB-US26D – Frequently Asked Questions

1) How do I keep the inactive leaf of a pair of doors locked without an exit device?
A surface bolt is the usual answer, and the Ives SB1630 is the heavy duty steel version of it. It mounts on the face of the inactive leaf and throws a 1 inch bolt into a strike, so the inactive leaf becomes the fixed jamb the active leaf latches against. Order it with a top strike (T), a bottom strike (B), or both (TB) depending on whether you want the leaf held at the head, the threshold, or both points. Fasteners are fully concealed once installed, so the bolt can't be unscrewed off the door.
2) What is the difference between the SB1630 B, T, TB, BL, TL and TBL options?
The letters are the strike package and whether the bolt locks. B is bottom strike only, T is top strike only, TB gives you both a top and a bottom strike. Add an L and you get the locking bolt: BL is locking with bottom strike, TL is locking with top strike, TBL is locking with top and bottom strikes. The locking versions are keyed and hold the bolt in both the thrown (up) and retracted (down) position, so nobody can drop the bolt or free the leaf without the key. Every option is offered in 604 clear zinc, 626 satin chrome, and 613 satin bronze oil rubbed.
3) Do I need a keyed surface bolt, or will a plain one do?
It depends on who has access to the inactive leaf. In a back-of-house or staff-only area, a non-locking bolt (SB1630 in B, T, or TB) is enough, because nobody is going to work the bolt but the person who should. Where the pair faces a public corridor, a tenant lobby, or a retail floor, take the locking option (BL, TL, TBL). Keyed operation holds the bolt up or down, so a passerby can't retract it and swing the inactive leaf open. Each locking bolt comes with 2 keys, and you pick the key code at order time: 1289 standard, or 1360, 1390, or 1395.
4) Is a steel surface bolt overkill compared to a solid brass one for a commercial opening?
For a commercial or institutional pair, no. The SB1630 is heavy duty steel and carries the ANSI/BHMA A156.16 L84161 designation with a UL fire listing, which is what a spec or an AHJ on a fire rated opening will look for. The solid brass alternatives ZenSupply stocks, like the Emtek 8511 6 inch surface bolt or the Delaney solid brass surface bolt, are the right call on a residential or decorative interior door where appearance leads and there's no fire or code requirement to satisfy. Also in the commercial range: the ABH HD1805, a heavy duty bolt with an auto-locking 3/4 inch stainless bar, and the Trimco 4800 Series.
5) Can I use an Emtek 8511 solid brass surface bolt on a fire rated double door instead of an Ives SB1630?
The Emtek 8511 is a 6 inch solid brass surface bolt, a decorative-grade flush-mounted bolt for holding an inactive leaf. The Ives SB1630 is the one carrying the fire credential: it is a heavy duty steel bolt, UL listed for 3 hour fire doors up to 10 feet, and it meets ANSI/BHMA A156.16 L84161. If the opening is a rated assembly and the inspector is checking the bolt on the inactive leaf, specify the SB1630. The Emtek 8511 suits interior double doors, French doors, and closet pairs where the look of solid brass matters and no fire rating is being called out.
6) Can I get all my SB1630 locking bolts keyed alike across a building?
Within limits, yes. The SB1630 locking bolt is furnished with 2 keys in one of 4 key codes: 1289 (the standard code), 1360, 1390, or 1395. Order every bolt on the same code and one key runs them all, which is what a property manager standardizing a fleet of doors wants. Order different codes to separate buildings or floors from each other. This is a fixed code set, not a keyway you can key into an existing master system.
7) Will the SB1630 bolt reach into my existing floor strike or head strike?
The SB1630 throws 1 inch, which is a long throw for a surface bolt and gives it real engagement into a floor or head strike, but the strikes are furnished with the bolt rather than being something you match to what's already there. Ives supplies a 1-1/4 x 7/8 x 15/16 inch strike, and you order the package with a top strike, bottom strike, or both. Plan on setting the supplied strike rather than reusing the old one, since the throw and the strike pocket are matched to each other.
8) What comes in the box with the Ives SB1630, and what do I still have to supply?
The SB1630 ships with wood screws and machine screws, an end plug, and an end plug stud package, plus the strike or strikes for the option you ordered. The wood and machine screws mean it covers both a wood door and a metal door out of the same box. Keys come with the locking (L) versions. What isn't in the box is anything for the floor prep, so on a bottom strike installation into concrete or terrazzo, plan the anchoring for the floor material yourself.
9) What is the alternative to the SB1630 if I want the bolt to lock itself instead of being keyed?
The ABH HD1805 is the auto-locking option ZenSupply carries, with a 3/4 inch stainless steel bar that locks on its own rather than needing a key turned. The Ives SB1630 takes the other approach: keyed control in both the up and down positions, so the bolt stays exactly where the keyholder left it and no one else moves it. Pick the SB1630 when you want the leaf's state controlled by whoever holds the key, and the auto-locking bolt when you want it to secure itself every time it's thrown.
10) Can someone unscrew the surface bolt off the door to get through?
Not without defeating the bolt itself. The SB1630 mounts with fully concealed fasteners, so there are no exposed screw heads on the face of the installed bolt to attack with a driver. Combine that with the keyed locking version and the bolt can't be retracted or removed by anyone without the key, which is the setup for a pair of doors facing a public area or an opening that's had vandalism problems.
11) I do not need a keyed bolt, I just need to hold the inactive leaf. What is a simpler alternative to the Ives SB1630?
Two directions. Staying within the SB1630 family, the non-locking configurations are the plain bolt versions - top strike only, bottom strike only, or top and bottom strike - which throw and retract by hand while keeping the same heavy duty steel body and the 3 hour UL fire listing. Stepping outside it, the Delaney Solid Brass Surface Bolt is a straightforward solid brass hand-operated bolt, and the Trimco 4800 Series is Trimco's surface bolt line. Use the plain SB1630 versions when the opening is fire rated and the specification still applies; use the Delaney or Trimco bolts on non-rated interior pairs where a basic manual bolt is all the opening asks for.
12) Is a Delaney decorative brass surface bolt an equivalent substitute for an Ives SB1630 in a commercial building?
They serve different openings. The Delaney BV7600 is a decorative solid brass surface bolt, built around appearance for residential and light interior pairs. The Ives SB1630 is specified as commercial heavy duty in steel, meets ANSI/BHMA A156.16 L84161, mounts with fully concealed fasteners so the bolt cannot be unscrewed off the door face, and is UL listed for 3 hour fire doors up to 10 feet. On an office, healthcare, education, or multi-family corridor pair, the SB1630 is the one written into the hardware schedule. The Delaney decorative bolt fits a residence or a light-duty interior door where the finish detail is the point.
13) Which SB1630 finish matches the rest of my door hardware?
Three finishes cover the SB1630 across every strike and locking option: 626 satin chrome, 604 clear zinc, and 613 satin bronze oil rubbed. 626 is the one that lines up with typical commercial satin chrome levers and closers. 604 clear zinc is the utility finish for back-of-house and industrial openings where nobody's matching anything. 613 is the dark oil rubbed bronze for hospitality and multi-family corridors running a bronze package.
