Don-Jo 1572 Dust Proof Strike in Cast Brass, 15/16" x 2" — Lockable Commercial Door Hardware

The Don-Jo 1572 Dust Proof Strike is a compact, cast-brass floor strike designed to receive and protect the bottom bolt of a flush-bolt door.

Don-Jo 1572-626 – Frequently Asked Questions

1) What size hole does the Don-Jo 1572 dust proof strike need in the floor?
The 1572 is 15/16 inch in diameter with a 2 inch depth, so the floor prep has to be a round bore of at least 15/16 inch taking the full 2 inch body. On concrete that means a core or hammer-drilled hole; on wood or a threshold, a bore of the same diameter. If your existing prep is larger than 15/16 inch, an adjustable strike like the Trimco 3911 Series is the better fit for covering an oversized opening.
2) What is a dust proof strike for on a pair of doors with flush bolts?
It is the floor receiver for the bottom flush bolt on the inactive leaf of a paired opening. The 1572 has a spring-loaded cover that sits flush and closes over the hole when the bolt is retracted, so dirt and grit stay out of the prep and the bolt still drops cleanly next time. Without one, the bare floor hole packs with debris and the bottom bolt stops seating.
3) Does the Don-Jo 1572 meet an ANSI/BHMA standard for institutional specs?
Yes. The 1572 is listed to ANSI/BHMA A156.16 under function number L24021, which is the auxiliary hardware standard designation institutional and government specs typically call out for dust proof strikes.
4) Can I use the Don-Jo 1572 to replace a worn floor strike without redoing the floor?
Yes, if the existing bore is 15/16 inch and at least 2 inches deep, the 1572 drops straight into it. If the old strike was larger or the hole has spalled out oversize, you will either need to patch and re-drill or move to an adjustable-type strike such as the Trimco 3911 Series.
5) Can the Don-Jo 1572 be used as the bottom strike for a surface vertical rod exit device?
The Don-Jo 1572 is intended for paired wood or metal doors using compatible bottom flush bolts, and is sized at 15/16 inch diameter by 2 inches deep. For a surface vertical rod exit device, the strike is normally supplied as a device-matched part: the Detex 96B Strike Kit, for example, is the bottom dust proof strike for Detex 50 Series surface vertical rod exit devices and belongs to the 90 Strike Series. If the opening has an exit device rather than flush bolts, match the strike to that device family instead of substituting the 1572.
6) What is the difference between the Don-Jo 1572 dust proof strike and the Trimco 3911 adjustable dust proof strike?
Both receive the bottom bolt of a flush-bolt door and use a spring-loaded cover to keep dirt out of the floor prep. The Don-Jo 1572 is a fixed cast brass strike measuring 15/16 inch in diameter by 2 inches deep. The Trimco 3911 Series is an adjustable dust proof strike, so its height can be set relative to the finished floor rather than being fixed at one depth. Choose the 1572 when the floor prep matches its 15/16 inch by 2 inch dimensions; choose the adjustable 3911 when floor covering thickness or an existing oversized prep means the strike height has to be dialed in.
7) What finishes does the Don-Jo 1572 dust proof strike come in?
Three: polished brass, oil rubbed bronze, and satin chrome. Pick the one that matches the flush bolts and door trim already on the opening, since the cover plate is the only part visible once installed.
8) Is the Don-Jo 1572 brass all the way through or just plated?
The body is cast brass, not plated steel or zinc, then finished in one of the three plating options. Cast brass holds up to the repeated bolt strikes and floor moisture that a threshold-level part sees.
9) For standardizing dust proof strikes across a building, does the Don-Jo 1572 cover every opening?
The Don-Jo 1572 covers the common case: interior double-door openings in offices, retail, schools, healthcare, hospitality and multi-family that use bottom flush bolts, and it meets ANSI/BHMA A156.16, L24021. It comes in polished brass, oil rubbed bronze and satin chrome so it can be matched to existing trim. Openings that fall outside that pattern still need their own part, such as the Detex 96B Strike Kit for Detex 50 Series surface vertical rod exit devices, or the adjustable Trimco 3911 Series where strike height has to be set to the floor. Expect the 1572 for flush-bolt pairs and device- or adjustment-specific strikes for the rest.
10) Is a dust proof strike kit for an exit device the same thing as the Don-Jo 1572?
They do the same job in different systems. The Don-Jo 1572 is a single cast brass round strike, 15/16 inch in diameter by 2 inches deep, that drops into a floor prep to receive a bottom flush bolt. The Detex 96B is supplied as a strike kit tied to Detex 50 Series surface vertical rod exit devices within the 90 Strike Series, so it is specified by the device it serves rather than by a bare dimension. Ordering one where the other is required will leave you with a strike that does not line up with the bolt or rod in the door.
11) Is the Don-Jo 1572 rated for commercial traffic or is it a residential part?
Don-Jo classes the 1572 as commercial, and the description calls out office and retail openings, schools, healthcare and institutional buildings, plus hospitality and multi-family. It also works on residential paired doors using compatible flush bolts.
12) How is the Don-Jo 1572 packaged if I am buying several for a building standard?
Sold each, individually polybagged. That suits ordering one per inactive leaf across a set of openings and keeping the finish protected in the van or on the shelf until install.
