Don-Jo D9103-630 – Frequently Asked Questions

1) What size is the Don-Jo D9103 extended lip strike, and how is the 3 inch width measured?
The D9103 measures 2-1/4 inches high by 3 inches wide, and the width is taken from the center of the screw hole to the end of the lip, not across the whole plate. That distinction matters when you are matching an extended lip to a frame that sits back from the door face: the lip portion is what reaches out past the screw line, so measure your existing strike the same way before comparing.
2) Why would I use an extended lip strike instead of a standard flat strike?
An extended lip is for openings where the frame or jamb face is set back from the door, or where trim, a wide gap, or an out-of-plumb condition means a standard lip does not reach far enough to guide the latch in. The lip carries the latchbolt across that gap and onto the strike opening instead of letting it catch on the frame edge. On the D9103 that reach is what the 3 inch dimension from screw hole center to lip end describes. If your door closes flush against the stop with no setback, you do not need the extended lip.
3) Is the D9103 a strike for a single door, or can I use it on a pair of doors with no mullion?
The D9103 is a lip strike that mounts to the frame jamb and catches a latchbolt, so it serves a single active leaf. A pair of doors without a mullion needs a strike made for that condition, mounted to the inactive leaf or to the head and threshold. Detex builds a 92 Strike Kit for double door applications, supplied with tamper resistant fasteners, which is the right family for that opening rather than a jamb-mounted lip strike.
4) I need a strike for a round pipe or tube frame, will the Don-Jo D9103 work?
No. The D9103 is a flat lip strike and it wants a flat jamb face to sit against. A round pipe post or tubular frame needs a strike shaped for that curve, and Trimco makes the 1260P pipe adapter strike in its 1260 Series for exactly that condition. Trying to force a flat plate onto a round section leaves the lip unsupported and the screws pulling at an angle.
5) Is the Detex 92 strike kit a substitute for the Don-Jo D9103 extended lip dimple strike?
No - they solve different problems. The Don-Jo D9103 is an extended lip dimple strike, a flat strike plate that captures a latch on a single door frame, offered in polished brass 605, matte black 622, satin stainless 630 and Duronodic DU. The Detex 92 Strike Kit belongs to the Detex 90 Strike Series and is built for a double door opening, supplied with tamper resistant fasteners. If you are replacing a damaged strike plate on one leaf of a standard frame, the D9103 is the part; if you are strikeing a pair of doors as part of a Detex 90 Series application, the 92 kit is the one to order.
6) What is a dimple strike and will it work with my cylindrical lockset?
The dimple refers to the latch hole configuration: a formed recess behind the strike opening that the latchbolt drops into, rather than a plain cut opening. It gives the latch a defined seat so it captures consistently. The D9103 is a dimple-style latch hole strike built for commercial door hardware, so it is intended for a standard latchbolt from a cylindrical or tubular lockset engaging at the strike face.
7) How heavy is the steel on the Don-Jo D9103 strike, and will it hold up in a high traffic entry?
18-gauge steel, .050 inch thick, which is a commercial-weight strike rather than a residential stamping. That thickness is what keeps the lip from deforming when a door gets pulled shut hard hundreds of times a day. It is rated by the manufacturer as a commercial product, which is the category schools, healthcare buildings, and multi-tenant properties buy for corridor and tenant doors.
8) What finishes does the Don-Jo D9103 strike come in, and which one matches my existing hardware?
Four finishes: 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For most commercial buildings 630 is the one that matches existing lever and closer hardware, since satin stainless is the standard commercial finish. Choose 605 only if the opening is bright brass throughout, and DU if the frames and hardware are the dark bronze anodized look common on aluminum storefront and older office buildings.
9) Can I replace the strike on my commercial door without replacing the lockset?
Yes, in most cases. A strike is frame hardware and it is independent of the lock body, so a worn, bent, or wrong-lip strike can be swapped on its own as long as the new plate covers the existing screw holes and the latch lines up with the strike opening. The D9103 is a direct piece of frame hardware in 18-gauge steel, sold in 10 packs, which makes it a common item for a maintenance shop to keep on the shelf for exactly this kind of repair.
10) What is the difference between a Don-Jo D9103 strike and a Trimco 1260P pipe adapter strike?
The Don-Jo D9103 is a conventional extended lip dimple strike in 18-gauge (.050) steel, measuring 2-1/4 inch high by 3 inch wide with the width taken from the center of the screw hole out to the end of the lip - it mounts to a door frame and catches the lockset latch. The Trimco 1260P is a pipe adapter strike, from the Trimco 1260 Series, and it is sold as the strike only. If the opening you are working on is a standard frame with a latch, the D9103 is the direct strike plate; a pipe adapter strike addresses a different mounting condition entirely and will not drop into a frame prep cut for a flat plate.
11) I need a tamper resistant strike for an exit device pair - can I use the Don-Jo D9103?
The Don-Jo D9103 is a commercial extended lip dimple strike for door hardware latch engagement, and it is sold in shelf packs of 10 for stocking replacements across a building. It is not described as a tamper resistant assembly. Where the requirement is specifically a double door strike supplied with tamper resistant fasteners, the Detex 92 Strike Kit in the Detex 90 Strike Series is the part written for that condition. Many facilities carry both: the D9103 for routine single-leaf strike replacement and the Detex 92 kit at the paired openings.
12) Do I have to buy Don-Jo D9103 strikes by the box, or can I get one?
The D9103 is packed in shelf packs of 10. For a property manager or maintenance shop standardizing strikes across a building that works in your favor, since you get the same finish and lip across every opening you touch. If you only need a single strike for one door, a pack of 10 is what you will be ordering.
13) What model number do I give my supplier for the Don-Jo extended lip dimple strike?
Don-Jo D9103, then the finish suffix: 605, 622, 630, or DU. The model alone identifies the 2-1/4 by 3 inch extended lip dimple strike; the finish is what turns it into a specific orderable item, and it is the piece distributors most often get left off a purchase order.
