Don-Jo 9125-619 – Frequently Asked Questions

1) What size is the Don-Jo 9125 extended lip strike, and how is the width measured?
The Don-Jo 9125 measures 2-1/4 inches in height and 2-1/2 inches in width. The width is taken from the center of the screw hole to the end of the lip, not overall plate width, so when you compare it against the strike currently in your frame, measure from the screw hole centerline out to the lip edge or you will come up short.
2) When do I need an extended lip strike instead of a standard strike plate?
You need the extended lip when the door is set back from the frame face, when there is a thick casing or trim the latch has to ride over, or when a gap between door and frame keeps the latch from reaching the standard strike lip. The extended lip on the 9125 carries the latch further out so it engages cleanly. If your latch already rides straight onto a flush frame face, a standard lip strike is the simpler part.
3) Will the Don-Jo 9125 fit a hollow metal frame with rounded strike prep?
Radius corners are available on the 9125, which is what you need for a hollow metal frame prepped with a rounded cutout. If your frame has a square cut prep, order the square corner version instead; dropping a radius corner plate into a square prep leaves visible gaps at the corners.
4) Will the Don-Jo 9125 extended lip strike work on a pair of doors with a vertical rod exit device?
The Don-Jo 9125 is a 2-1/4 inch by 2-1/2 inch 18-gauge extended lip strike with a single latch hole, intended for a standard commercial lockset latch in a frame jamb. A double-door exit device application is a different part: the Detex 92 Strike Kit is built for double door openings and comes with tamper resistant fasteners. If the opening is a pair of doors served by an exit device rather than a latch in the jamb, the 92 strike kit is the one matched to that condition.
5) I need a strike that mounts to a round post instead of a door frame. Can I use the Don-Jo 9125?
No. The 9125 is a flat extended lip strike sized 2-1/4 inches high by 2-1/2 inches wide, with the width measured from the center of the screw hole to the end of the lip, so it is meant to lie against a flat frame face. For latching into a round pipe or post, the Trimco 1260P is a pipe adapter strike, sold as the strike only, and is the part shaped for that condition.
6) Is the Don-Jo 9125 heavy enough for high traffic commercial doors?
It is built from 18-gauge (.050) steel and catalogued for commercial rather than residential use, which is the gauge you want on office, school, healthcare, retail and multi-tenant openings that cycle all day. Sold in shelf packs of 10, so it suits a facility standardizing strikes across a run of doors.
7) Does the 9125 work with a deadbolt as well as a latch?
No. The 9125 has a single latch hole, so it accepts one bolt only, the latchbolt from a standard commercial lockset. If your door has both a latch and a separate deadbolt, you need either a second strike or a two-hole (T-strike) plate for the pair.
8) I am replacing strikes on a storefront or an odd frame profile. Is the Don-Jo 9125 the right part?
It depends what the frame is. The 9125 is a flat steel strike for a conventional jamb face with screw holes and a lip. If you are strikng into round pipe or tubular frame, that needs a pipe adapter strike such as the Trimco 1260P, not a flat plate. Match the plate to the frame face you are actually screwing into.
9) What is the difference between ordering the Don-Jo 9125 and ordering a strike kit?
The Don-Jo 9125 is a single strike plate, 18-gauge (.050) steel, offered in eight finishes including DU, 605, 609, 619, 620, 622, 629 and 630, and packed in shelf packs of 10 for stocking. The Detex 92 Strike Kit is supplied as a kit for a double door opening and includes tamper resistant fasteners. Buy the 9125 when you are replacing plates across many openings and using the screws already specified for the frame; buy the kit when the fasteners and double-door hardware need to come in the box.
10) Is the Trimco 1260P an equivalent replacement for a Don-Jo 9125 extended lip strike?
They are not interchangeable. The 9125 is an extended lip strike with a single latch hole, where the extended lip carries the latch across a gap to the frame face. The Trimco 1260P is a pipe adapter strike from the 1260 Series. Confirm what the latch is closing against, a flat frame jamb or a pipe, before substituting one for the other.
11) What finishes does the Don-Jo 9125 strike come in?
Eight: polished brass (605), antique brass (609), satin nickel (619), antique nickel (620), matte black (622), bright stainless (629), satin stainless (630), and duronodic brown coated (DU). If you are matching existing levers or hinges on an opening, 630 satin stainless is the usual commercial default and 605 is the match for polished brass trim.
