Don-Jo 1578-626 – Frequently Asked Questions

1) Will the Don-Jo 1578 surface bolt work on a door with a rim strike, or do I need a mortise prep in the frame?
Either prep works. The 1578 ships with both a rim strike and a mortise strike in the box, so you can surface-apply the strike to the frame face or the threshold, or mortise it in where you want the cleaner look. That is the main reason to pick it over a bolt that comes with only one strike, since you can decide on site once you see what the frame or floor will take.
2) How long is the Don-Jo 1578 surface bolt and how wide is the plate?
The 1578 measures 8 inches in length and 1 inch in width. That 1 inch width is what decides whether it fits your application: it needs a inch of flat, unobstructed face on the stile or the inactive leaf to sit on, so check narrow-stile aluminum doors and glazing stops before ordering. On a standard hollow metal or wood door leaf the 8 inch body mounts without conflict.
3) What ANSI number does the Don-Jo 1578 surface bolt meet? My spec calls out a surface bolt by ANSI code.
It conforms to ANSI L84161. If your drawing or hardware schedule calls that number, the 1578 answers it directly, which is the usual case on institutional and government jobs where the schedule specifies by ANSI designation rather than by manufacturer part number.
4) Can the Don-Jo 1578 surface bolt be locked or keyed?
No, it is a manually thrown bolt with no keying and no auto-lock. If you need the bolt itself secured against being retracted from the room side, the Ives SB1630 is a heavy duty steel locking surface bolt with keyed security and a 1 inch throw. If you want the bolt to catch on its own when the door closes, the ABH HD1805 has an auto-locking 3/4 inch stainless steel bar.
5) Can I use a surface bolt like the Don-Jo 1578 instead of a flush bolt on the inactive leaf of a pair?
Yes, and it is the usual retrofit move. A flush bolt has to be mortised into the edge of the leaf, which means routing the door. The 1578 mounts to the face of the door with a concealed-mount configuration, so no edge prep is needed, which is why it goes on existing pairs where you cannot pull and machine the leaf. Trade-off is that the bolt body sits proud of the face rather than hidden in the edge.
6) What is the closest solid brass alternative to the Don-Jo 1578 surface bolt?
The Don-Jo 1578 is a brass surface bolt in Satin Chrome (626). Two brass peers cover the same job: the Emtek 8511 is a solid brass surface bolt in a 6 inch length, and the Delaney Solid Brass Surface Bolt is a plain solid brass unit. The 1578 measures 8 inches long by 1 inch wide, so the Emtek 8511 sits two inches shorter if you are matching an existing mounting pattern on the door.
7) The Don-Jo 1578 is not fire rated. What surface bolt should I use on a fire rated opening?
For a labeled opening, use a fire rated surface bolt. The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and carries a fire rating; the Ives SB1640 is a fire rated brass surface bolt with a 1 inch throw; and the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, carrying a 3-hour UL listing. The Don-Jo 1578 is a commercial brass surface bolt conforming to ANSI L84161.
8) What is the difference between the Don-Jo 1578 and a heavy duty steel surface bolt like the Ives SB360?
Material and reach. The 1578 is brass, 8 inches long, commercial grade to ANSI L84161. The Ives SB360 is heavy duty steel in a 12 inch length with a 1-1/4 inch throw, and the ABH HD1805 is a heavy duty bolt with an auto-locking 3/4 inch stainless bar. Go brass when finish match and corrosion resistance drive the choice; go steel and longer when you need the bolt to reach a header or floor strike that is further from the mounting point, or want auto-locking action.
9) Is the Don-Jo 1578 surface bolt suitable for a residential entry or interior door?
It is built for commercial duty, so it will hold up fine residentially but the look is plain functional hardware, not decorative. If the door is in a home and appearance is driving the choice, the Delaney Decorative Solid Brass Surface Bolt or the Emtek 8511 solid brass surface bolt in 6 inch are the decorative brass options we carry. For office buildings, schools, healthcare, retail, and multi-tenant residential, the 1578 is the right class of part.
10) Is the ABH HD1805 a drop-in replacement for the Don-Jo 1578?
No. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so the bar is stainless and narrower than the 1 inch width of the Don-Jo 1578, and it latches automatically on throw instead of sliding free. The 1578 is a brass bolt 8 inches long by 1 inch wide, furnished with both rim and mortise strikes. Confirm the strike prep and mounting hole pattern on the door before swapping either way.
11) If I am standardizing surface bolts across a facility, how does the Don-Jo 1578 compare to the Trimco 4800?
The Don-Jo 1578 is a single model, 8 inches by 1 inch in brass with Satin Chrome (626), conforming to ANSI L84161, and ships with both rim and mortise strikes so one part covers two frame preps. The Trimco 4800 is a surface bolt series rather than a single part, so a facility standard built on it means selecting within the series per opening. For openings needing a heavier steel bolt in the same program, the Ives SB1600 is heavy duty steel with a 3-1/2 inch throw.
12) My opening needs a longer bolt throw than the Don-Jo 1578 provides. What should I use?
For a deeper throw into the strike, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw, and the Ives SB360 in the 12 inch length is a heavy-duty steel surface bolt with a 1-1/4 inch throw. Both are steel rather than the brass used on the Don-Jo 1578. Longer throw is what you want where the bolt drops into a floor socket or reaches a header strike set back from the door face.
