Don-Jo 1573-626 – Frequently Asked Questions

1) What does a Don-Jo 1573 dust proof strike actually do in a door frame?
A dust proof strike sits in the floor (or in the frame at the threshold) and receives the bottom bolt of a flush-bolted door, usually the inactive leaf of a pair. Its job is to keep dust, grit and drafts out of the bolt pocket while the door is open, so the bolt still drops cleanly when you close the leaf. The 1573 is a cast brass unit that can also be locked closed, so the pocket stays sealed on openings where nothing should collect in it.
2) Will the Don-Jo 1573 strike fit the cutout I already have in the floor?
The 1573 face plate measures 2-1/4 by 2-7/8 inches. If your existing dust proof strike has the same plate footprint, it drops into the same mortise; if the old plate is smaller, you will be enlarging the cutout, and if it is larger you will see a gap around the new plate. Measure the existing plate before you pull it, not the hole.
3) Can I use the Don-Jo 1573 as the bottom strike for a surface vertical rod exit device?
Not as a substitute for a device-specific strike. Surface vertical rod exit devices generally call for the strike the device manufacturer supplies for that series. For Detex 50 Series surface vertical rod devices, the matching part is the Detex 96B Strike Kit bottom dust proof strike from the 90 Strike Series. The 1573 is the general-purpose floor strike for flush and surface bolts on a pair of doors.
4) Can I use a Detex 96B strike kit in place of a Don-Jo 1573 dust proof strike?
No - they solve different problems even though both are floor strikes. The Detex 96B Strike Kit is a bottom dust proof strike made for Detex 50 Series surface vertical rod exit devices, so it is matched to the bottom rod and bolt geometry of that device family and belongs on an exit door running that hardware. The Don-Jo 1573 is a general commercial dust proof strike in cast brass, 2-1/4 inches by 2-7/8 inches, sized for the flush bolt or dust proof strike pocket in a standard frame or floor. If the door has a Detex 50 Series surface vertical rod device on it, order the 96B kit that goes with the device. If you are replacing the strike under a pair of doors with manual flush bolts, the 1573 is the part.
5) What is an equivalent dust proof strike to the Don-Jo 1573 if the floor prep needs height adjustment?
The Trimco 3911 Series Adjustable Dust Proof Strike is the peer to look at when the strike has to be brought up or down to meet the bolt. The Don-Jo 1573 is a fixed cast brass dust proof strike measuring 2-1/4 inches by 2-7/8 inches with a lockable closed plunger, so it seats at the depth the mortise gives it; the Trimco 3911 is built as an adjustable unit. On a slab where the finished floor height changed after the frame went in, or where a topping pour raised the threshold, the adjustable 3911 lets you set the strike to the bolt without re-cutting the pocket. Where the floor is at plan height and you want solid cast brass and the ability to lock the strike closed while the door stands open, the 1573 answers it directly.
6) Do I need a dust proof strike for every pair of doors with flush bolts?
You need one wherever a bottom flush bolt or a surface bolt throws into the floor. The bolt has to land in a lined pocket, otherwise the concrete chips out and the pocket fills with debris until the bolt will not seat. Top bolts throw into the frame head and use a different strike, so a typical pair of doors takes one floor strike like the 1573, not two.
7) What is the difference between the Don-Jo 1573 and the Trimco 3911 dust proof strike?
Both are floor-mounted dust proof strikes. The Trimco 3911 Series is an adjustable strike, meaning the receiving portion can be set to suit bolt depth or floor conditions. The Don-Jo 1573 is a fixed cast brass unit with a 2-1/4 by 2-7/8 inch plate that can be locked closed. If your bolt projection or floor covering thickness is uncertain, the adjustable Trimco gives you room to tune it; if the opening is straightforward, the 1573 is the simpler part.
8) Is cast brass worth it for a floor strike, or is a stamped one fine?
Cast brass is the material to pick where the strike is in a walked-on, mopped floor. It holds thread for the mounting screws better than thin stamped stock and it does not rust when standing water gets into the pocket. The 1573 is solid cast brass, which is also why it is finished in true architectural finishes rather than painted.
9) Is the Don-Jo 1573 dust proof strike rated for commercial traffic?
It is a commercial-grade part, cast brass, and specified for offices, schools, healthcare, retail, government buildings, warehouses and multi-tenant residential. A property manager standardizing floor strikes across a building can run the same 1573 on every pair of doors and just hold the finish constant.
