Don-Jo 1570-626 – Frequently Asked Questions

1) What does a dust proof strike like the Don-Jo 1570 actually do, and do I need one?
A dust proof strike is the floor socket that receives the bottom flush bolt or vertical rod on an inactive door leaf. The Don-Jo 1570 keeps that floor socket clear of dirt and debris while the door stands open, so the bolt drops all the way in when the door closes. If you have a pair of doors with flush bolts, or a surface vertical rod device that bolts into the floor, you need one at every bolt location. If nothing bolts into your floor, you don't.
2) How big is the Don-Jo 1570 dust proof strike, and will it cover my existing floor cutout?
The 1570 measures 2-1/4 by 2-7/8 inches. That is the face plate footprint, so measure your existing floor prep against those two numbers before you pull the old strike. If the current cutout is larger in either direction, the 1570 won't cover it and you'll want a larger plate or an adjustable strike such as the Trimco 3911.
3) Does the Don-Jo 1570 meet ANSI L24021?
Yes, the 1570 is built to ANSI L24021, the function designation for a dust proof strike. If your hardware schedule calls out L24021 on the pairs, this satisfies that line item, which is the usual sticking point on institutional and government submittals.
4) My bottom bolt doesn't line up with the floor strike. Is the Don-Jo 1570 adjustable?
No. The 1570 is a fixed cast brass strike at 2-1/4 by 2-7/8 inches, so the bolt has to land where the socket is. If your bolt is off center or the door has settled, use an adjustable strike instead. The Trimco 3911 Series is the adjustable dust proof strike we carry for exactly that problem.
5) Can a Detex 96B strike kit be used in place of a Don-Jo 1570 dust proof strike?
They are not interchangeable. The Detex 96B Strike Kit is a bottom dust proof strike supplied for Detex 50 Series surface vertical rod exit devices and belongs to the Detex 90 Strike Series, so it is matched to that exit device's bottom rod. The Don-Jo 1570 is a standalone cast brass dust proof strike, 2-1/4 inches by 2-7/8 inches, for a floor socket at a flush bolt or comparable bottom bolt. If the opening has a Detex 50 Series surface vertical rod device on it, order the 96B kit; if the floor socket is independent of a Detex exit device, the 1570 is the part.
6) What is a comparable dust proof strike to the Don-Jo 1570 if an adjustable one is needed at the floor socket?
The Trimco 3911 Series Adjustable Dust Proof Strike is the adjustable counterpart. The Don-Jo 1570 is a fixed cast brass dust proof strike measuring 2-1/4 inches by 2-7/8 inches, so it sets the socket at one dimension; the Trimco 3911 is built as an adjustable strike, which is the one to specify when the floor socket depth or the plunger travel has to be tuned after the door and threshold are set. For a straight like-for-like replacement of an existing cast brass strike, the 1570 is the direct match.
7) Is the Don-Jo 1570 dust proof strike solid brass or plated steel?
Cast brass, solid through. That matters where the strike sits in the floor and takes mopping, salt, and standing water at an entrance, since a plated steel plate will rust out at the bolt hole first. Cast brass is also why the 613 oil rubbed and 605 polished brass finishes look right next to brass door hardware rather than approximating it.
8) What finishes does the Don-Jo 1570 dust proof strike come in, and how do I match it to my other door hardware?
Five: 605 polished brass, 612 satin bronze, 613 oil rubbed bronze, 625 polished chrome, and 626 satin chrome. Match the BHMA number on your existing lever or exit device rather than eyeballing it. Most commercial openings run 626 satin chrome, and 613 is the common pick where the rest of the trim is dark bronze.
9) Which dust proof strike should be standardized across a facility where finishes have to match existing door hardware?
The Don-Jo 1570 is the one to standardize on when finish coordination drives the decision. It is offered in 605 polished brass, 612 satin bronze, 613 oil rubbed bronze, 625 polished chrome and 626 satin chrome, so a single cast brass strike can be carried across brass, bronze and chrome hardware sets in the same building. The Trimco 3911 Series and the Detex 96B Strike Kit are the alternatives to consider when the requirement is adjustability or a Detex 50 Series surface vertical rod device rather than finish matching.
10) Can I buy just one Don-Jo 1570, or does it come in a multi-pack?
The 1570 ships in a shelf pack of 10. For a property manager doing one pair of doors that is more than you need in the moment, but pairs of doors almost always come in fleets, and having spares on the shelf beats a second trip when a floor socket gets crushed.
11) Is the Don-Jo 1570 dust proof strike suitable for a high traffic commercial entrance?
It's a commercial-grade part, cast brass rather than stamped, and it is the type used on office, school, healthcare, retail, warehouse, and municipal openings. Wear on a floor strike comes from the bolt cycling and from grit tracked in, which is what the cast body and the dust proof design address.
