Don-Jo 1581-626 – Frequently Asked Questions

1) Does the Don-Jo 1581 surface bolt come with the strike, or do I have to order it separately?
Both strikes ship with the Don-Jo 1581. You get a rim strike for surface mounting on the frame or the inactive leaf face, and a mortise strike for a cut-in prep in the frame or threshold, so one part covers either condition without a second order line. Pick the strike that matches the prep you already have and keep the other as a spare.
2) Will a 1-1/8 inch bolt throw reach my strike at the head or threshold?
The 1581 throws 1-1/8 inches. That is enough to engage a surface rim strike or a mortise strike set flush in the frame or floor, but if you have a raised threshold, a thick carpet build-up, or a deep gap between the leaf and the head, measure the actual travel you need first. Where you need much deeper engagement, the Ives SB360 throws 1-1/4 inches and the Ives SB1600 throws 3-1/2 inches.
3) Is the Don-Jo 1581 the right way to hold the inactive leaf of a pair of doors?
Yes, that is the job it does. A surface bolt mounts on the face of the inactive leaf and shoots into a strike at the head or the floor, holding that leaf fixed so the active leaf can latch against it. The 1581 is a 12 inch long, 1 inch wide bolt, so it gives a long mounting footprint on the stile. If you would rather the hardware not be visible on the door face, you want a concealed flush bolt cut into the edge of the leaf instead, not a surface bolt.
4) What does ANSI L84161 mean on this surface bolt, and is it UL rated?
L84161 is the ANSI/BHMA function designation Don-Jo publishes for the 1581, which is how a spec writer calls out this bolt on a hardware schedule. The 1581 is also UL Rated, which matters on openings where the hardware has to be listed. If your submittal calls for a specific hourly fire rating, the Ives SB1630 is listed at 3-hour.
5) What is the closest 12-inch surface bolt equivalent to the Don-Jo 1581?
The Ives SB360 in the US2C 12-inch configuration is the nearest match on length, a heavy-duty steel surface bolt with a 1-1/4 inch throw at 12 inches long. The Don-Jo 1581 is 12 inches by 1 inch in brass with a 1-1/8 inch throw and is furnished with both rim and mortise strikes, so the difference comes down to substrate, throw depth, and whether you want the two strike options in the box.
6) I need a deeper bolt throw than the Don-Jo 1581 gives me for a large gap between door and frame - what should I use?
Look at the Ives SB1600, a heavy duty fire rated steel surface bolt with a 3-1/2 inch throw. The Don-Jo 1581 throws 1-1/8 inch, which suits normal frame engagement; the SB1600's longer bar is intended for openings where the bolt must reach much farther into the strike or floor.
7) Is brass or steel better for a surface bolt in a wet or coastal location?
The 1581 is solid brass with a Satin Chrome 626 finish, which is the better choice where moisture or salt air would rust a plated steel bolt. If your concern is abuse rather than corrosion, heavy duty steel bolts like the Ives SB360 or the ABH HD1805 are the other direction to look. The Ives SB1640 is the closest brass alternative if you need a different length or throw.
8) What finish does the Don-Jo 1581 come in, and will it match my other door hardware?
Satin Chrome, BHMA 626, is the only finish the 1581 is built in. That is the standard commercial satin chrome that pairs with 626 cylindrical locks, 626 closers and US26D pulls, so it blends into most office, school and healthcare openings. If your building is standardized on brass or bronze tones, this bolt will read as a mismatch.
9) Can I use the Don-Jo 1581 on a storeroom or stockroom door in a school or hospital?
It is built for exactly that kind of work. The 1581 is a commercial grade bolt used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings, typically on the inactive leaf of a pair or on a door that stays secured from one side. One caution: a surface bolt on the egress side of a required exit is usually not permitted, so keep it on doors that are not part of the means of egress.
10) Is a 12 inch surface bolt too long for my door stile?
The 1581 body is 12 inches long by 1 inch wide, so you need a flat, uninterrupted run of at least 12 inches on the face of the stile plus clearance to the strike. On a narrow stile aluminum door or a leaf with glass close to the edge, that often will not fit. Short bolts exist for those openings, such as the Emtek 8511 at 6 inches.
11) Does the Don-Jo 1581 lock with a key?
No. The 1581 is a manually operated surface bolt, thrown and retracted by hand at the bolt, with no cylinder. If you need the bolt itself held by a key, the Ives SB1630 is a locking surface bolt with keyed security and a 1 inch throw. If you want it to catch automatically when the door closes, look at the ABH HD1805, an auto-locking surface bolt with a 3/4 inch stainless bar.
12) What is the difference between this surface bolt and a flush bolt?
A surface bolt like the 1581 screws onto the face of the door, so it can be added to an existing leaf with no routing and it is easy to see and service. A flush bolt is mortised into the edge of the door and sits hidden, which looks cleaner but requires machining the leaf. For retrofit work on doors already hung, the surface bolt is the practical pick.
13) What alternative to the Don-Jo 1581 comes in a range of sizes rather than one fixed 12-inch length?
The Trimco 4800 Series surface bolts are offered as a series rather than a single part, which is the route to take when you need to match several openings to different bolt lengths. The Don-Jo 1581 is a fixed 12 inch by 1 inch brass bolt with a 1-1/8 inch throw in Satin Chrome, well suited when you are standardizing on one size across a building.
