Don-Jo D9175-622 – Frequently Asked Questions

1) What size is the Don-Jo D9175 extended lip strike, and how is the 1-3/4 inch measured?
The D9175 measures 2-1/4 inches in height by 1-3/4 inches in width, and the width is measured from the center of the screw hole to the end of the lip, not across the face of the plate. That matters when you are checking lip projection past the frame: half the 1-3/4 inch figure is lip reach beyond the screw line. Measure your existing strike the same way before you match it.
2) What is an extended lip strike for, and when do I need one instead of a standard strike?
An extended lip strike is what you reach for when the latch has to ride past a deep frame, a thick trim, or a stop that a standard lip cannot clear. The lip guides the latchbolt in and shields the jamb from the latch dragging on it. The D9175 carries that longer lip in a 2-1/4 x 1-3/4 inch plate, with the width taken from the screw hole center out to the lip end. If your frame face sits flush and the latch already lands clean, a standard strike does the job and a long lip only sticks out into the opening.
3) Will the Don-Jo D9175 work on a pair of doors with no mullion?
No. The D9175 is a single lipped frame strike, and it mounts to a jamb. A pair of doors without a mullion has no jamb at the meeting point, so the lip has nothing to sit against. For that opening you want a strike built for double doors, such as the Detex 92 Strike Kit for double door applications from the 90 Strike Series.
4) What is a dimple strike, and does the dimple affect how the latch works?
The dimple is a formed depression at the latch hole rather than a plain punched opening. The latch rides into the recess instead of catching a flat edge, so the deadlatch plunger seats and the bolt drops in with less wear on the plate over time. The D9175 is built with that dimple latch hole. If you are replacing a strike where the latch has been scraping or hanging up on the plate edge, this is the style that fixes it.
5) How heavy is the steel on the Don-Jo D9175 strike plate?
18-gauge, .050 inch steel. That is the substance you want on a door that cycles all day, an office corridor, a school, a retail entry, a hospital wing. A thin residential strike distorts around the screw holes once the latch has slammed into it a few thousand times. 18 gauge holds the latch hole square.
6) What finishes does the Don-Jo D9175 strike come in?
Four: 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For matching what is already on the building, 630 is the one that pairs with the satin stainless and brushed chrome trim most commercial openings carry, 605 goes with bright brass lever sets, and DU matches dark bronze storefront and aluminum entry hardware. Order the finish that matches your existing strikes, not your levers, if the two differ.
7) I need a strike for a round post or pipe, not a flat frame. Will this one work?
It will not. A flat lipped plate like the D9175 needs a flat jamb face to seat against and screw into, and a round post gives it neither. For a pipe or post application the Trimco 1260P pipe adapter strike from the 1260 Series is the part designed for it.
8) Can I standardize on one strike across a whole building with the D9175?
That is the case for it. The pack of 10, the four finish choices, and one fixed 2-1/4 x 1-3/4 inch footprint mean every opening you convert gets the same plate, the same screw pattern, and the same spare on the shelf. Where it stops working is any opening that is not a standard flat jamb, so pairs without a mullion and post-mounted applications still need their own part.
9) How many Don-Jo D9175 strikes come in a pack?
They ship in a shelf pack of 10. That suits the way these actually get bought, a property manager refreshing strikes across a floor of units, or a locksmith keeping a box on the truck. If you need one strike for one door, you are still buying the ten.
10) Is the D9175 a residential or commercial grade strike?
Commercial. It is built for office buildings, schools, healthcare, retail, industrial and warehouse space, multi-tenant residential, and government buildings, which is where 18-gauge steel earns its keep. On a low-traffic interior residential door it is more strike than the opening needs, though nothing stops you using it.
