ABH ABH-HD1825TB-US32D – Frequently Asked Questions

1) Will the ABH HD1805 surface bolt work on a pair of doors without a mullion?
That's exactly what a surface bolt like the HD1805 is for. You mount it on the inactive leaf of a pair and throw the bar into a strike at the head or the sill, which holds that leaf fixed so the active leaf has something to latch against. The HD1805 ships with both top and bottom strikes, so one bolt covers either position without a separate strike order. The bar is 3/4 inch wide by 3/4 inch thick stainless steel, and it locks automatically when thrown; to release it you press the knob toward the door.
2) Does the ABH HD1805 surface bolt meet ANSI/BHMA A156.16?
The HD1805 meets ANSI/BHMA A156.16, which is the standard covering auxiliary hardware such as surface bolts. It is also Buy American Act qualified, which is what matters on federal, municipal and other publicly funded jobs where domestic sourcing is written into the spec. Both of those, plus all stainless construction, are the reason this one shows up on government and institutional door schedules.
3) Which surface bolt is the closest heavy duty equivalent to the ABH HD1805?
Among steel-bodied heavy duty bolts, the Ives SB360 is the nearest peer - a heavy-duty steel surface bolt with a 1-1/4 inch throw sold in a 12 inch length, matching the shortest of the HD1805 lengths. The ABH HD1805 runs 12, 24, 36, 48 and 60 inch lengths in 689 stainless steel with an auto-locking bar and ships with top and bottom strikes plus sex bolts. The Ives SB1600 is the other heavy duty steel option, with a 3-1/2 inch throw. The practical split is construction and reach: the HD1805 is all stainless and goes long, the Ives units are steel and fixed at the lengths their catalog lists.
4) What is a heavy duty alternative to the ABH HD1805 surface bolt for a fire rated door?
The Ives SB1630 heavy duty steel locking surface bolt carries a 3-hour UL listed fire rating with a 1 inch throw and keyed security, and the Ives SB1600 heavy duty steel surface bolt is fire rated with a 3-1/2 inch throw. The ABH HD1805 is a commercial all stainless steel bolt built on a 3/4 inch wide by 3/4 inch thick bar that meets ANSI/BHMA A156.16 and is BAA qualified, and it auto-locks rather than keying. On a labeled opening where the bolt itself has to carry a fire rating, the SB1630 or SB1600 is the one to spec.
5) I need a keyed surface bolt instead of an auto-locking one - what should I use in place of the ABH HD1805?
Specify the Ives SB1630, a heavy duty steel locking surface bolt with keyed security and a 1 inch throw, carrying a 3-hour UL listed fire rating. The ABH HD1805 secures by an auto-locking mechanism released by pressing the knob toward the door, and it takes a padlock up to a 3/8 inch shackle diameter with a 1-3/4 inch minimum shackle opening height rather than a cylinder. So the choice is between padlock-and-auto-lock on the HD1805 and a key cylinder on the SB1630.
6) What comes in the box with the ABH HD1805 surface bolt?
The bolt ships with a top strike, a bottom strike, and sex bolts for mounting. Sex bolts mean it's set up to go through the door and clamp from both faces rather than relying on wood screws, which is why it holds up on hollow metal and on doors that get abused. You supply nothing else for a standard install beyond drilling to the ABH template.
7) Is a heavy duty surface bolt like the HD1805 overkill for a residential door?
For a house, yes. The HD1805 is catalogued commercial only and built for extreme-use work: warehouses, back-of-house retail, government buildings, healthcare restricted access. For interior residential doors, French doors or a closet pair, the Emtek 8511 solid brass surface bolt at 6 inches or a Delaney decorative solid brass bolt is the right scale and finish. Step up to the ABH when the door takes real traffic or the opening is part of a security plan.
8) What's the difference between an auto-locking surface bolt and a plain one?
A plain surface bolt relies on friction in the guide to stay put, so vibration or a hard slam can walk it back out. The ABH HD1805 locks itself the moment the bar is thrown and stays locked until someone presses the knob toward the door to release it. On a door that gets hit by carts or wind loading, that's the difference between the inactive leaf staying fixed and the whole pair going slack. It also means one deliberate motion to release, which matters if staff are operating it a dozen times a shift.
9) Can I standardize on the ABH HD1805 across a whole facility?
It's a reasonable single standard for commercial openings. One model covers 12 through 60 inch lengths, plus custom, in a single 689 stainless finish, so every opening in the building takes the same part in a different bar length and everything matches visually. Each bolt arrives with its own top and bottom strikes and sex bolts, so stocking spares is one line item rather than a kit of pieces. The exception is any labeled fire door, where you need a bolt carrying the rating your assembly requires.
10) Is a solid brass surface bolt an acceptable substitute for the ABH HD1805 on a commercial door?
They are different classes of hardware. The Delaney solid brass surface bolt, the Delaney decorative solid brass surface bolt and the Emtek 8511 solid brass surface bolt in 6 inch are brass-bodied bolts suited to lighter and more decorative openings. The ABH HD1805 is a commercial all stainless steel bolt with a 3/4 inch wide by 3/4 inch thick bar built for extreme-use applications and meeting ANSI/BHMA A156.16. If the opening is an industrial, warehouse or back-of-house door taking daily traffic, the brass bolts are not carrying the same duty; if it is a decorative interior pair of doors, they are the intended product.
11) What is the difference between the ABH HD1805 and the Ives SB1640 surface bolt?
The Ives SB1640 is a fire rated brass construction surface bolt with a 1 inch throw. The ABH HD1805 is all stainless steel in a 689 finish with a 3/4 inch wide by 3/4 inch thick bar, offered in 12 through 60 inch lengths, ANSI/BHMA A156.16 compliant and BAA qualified. The SB1640 answers a fire rating requirement in brass; the HD1805 answers extreme-use duty, corrosion resistance and domestic sourcing on federal and institutional work.
12) Can I standardize a facility on one surface bolt series across both decorative and service doors?
Most facilities end up with two lines rather than one. The ABH HD1805 covers the heavy end - all stainless steel, 3/4 inch by 3/4 inch bar, ANSI/BHMA A156.16, BAA qualified, in 12 through 60 inch lengths for tall or oversized leaves. The Trimco 4800 Series surface bolts and the Delaney decorative solid brass surface bolt cover openings where appearance drives the selection. Where a leaf is fire rated, the Ives SB1600 and SB1640 are the fire rated units. Standardizing the HD1805 across the service, warehouse and back-of-house doors and running a second series on the public-facing ones is the usual split.
13) Will a 6 inch surface bolt work where the ABH HD1805 is specified?
Not usually. The Emtek 8511 solid brass surface bolt is a 6 inch bolt, roughly half the reach of the shortest ABH HD1805, which starts at 12 inches and runs to 24, 36, 48 and 60 inches. Long bolts are specified when the throw has to reach a header or threshold well above or below the bolt body, so a 6 inch brass bolt will not cover a spec written around a 24 inch or longer stainless bar. Where the spec is simply for a short interior bolt, the Emtek 8511 or the Delaney solid brass surface bolt is the shorter, simpler option.
14) Which surface bolt has the longest throw, the ABH HD1805 or the Ives models?
Among the Ives bolts, the SB1600 has the longest stated throw at 3-1/2 inches, followed by the SB360 at 1-1/4 inches, with the SB1630 and SB1640 at 1 inch. The ABH HD1805 is distinguished instead by bar section and overall length - a 3/4 inch wide by 3/4 inch thick stainless bar in 12 through 60 inch lengths. If the deciding factor is how far the bolt projects into the strike, compare the Ives throws directly; if it is how far the bolt body spans the leaf, the HD1805 is the one that scales.
