Don-Jo 9234-630 – Frequently Asked Questions

1) Will the Don-Jo 9234 T strike fit my existing frame cutout?
The 9234 is a T strike measuring 2-3/4 inches by 1-1/8 inches with a single latch hole. That 1-1/8 inch width is the giveaway: it drops into a frame prepped for a T strike, which is the narrow-lip prep common on hollow metal frames, not the wider 4-7/8 inch ANSI prep. If your frame currently holds a full ANSI strike, the 9234 will not cover the opening. Pull the old strike, measure the plate and the screw centers, and match the 2-3/4 x 1-1/8 footprint before ordering.
2) Can I use the Don-Jo 9234 T strike on a pair of doors with no mullion?
No. The 9234 is a frame-mounted T strike with a single latch hole, meant for a door latching into a jamb or a mullion. A pair of doors without a center mullion needs a strike made for that condition, mounted to the inactive leaf. The Detex 92 Strike Kit from the 90 Strike Series is a double door strike kit and comes with tamper resistant fasteners, which is the direction to look for that opening.
3) Is the Don-Jo 9234 T strike the right part for a pair of doors with a vertical rod exit device, or do I need a different strike?
The 9234 is a T strike for a single latch hole, 2-3/4 inches high by 1-1/8 inches wide, cut from 16-gauge (.062) steel and mounted in the frame to receive one latch. A pair of doors with an exit device does not present a frame jamb for that latch to catch, so the part that serves that opening is a double door strike such as the Detex 92 Strike Kit, which is supplied as a double door strike kit with tamper resistant fasteners. Use the 9234 where a latch strikes the jamb of a single door opening, and the Detex 92 kit where the strike has to serve a double door application.
4) My latch has to catch on a round post rather than a flat frame face. Will a Don-Jo 9234 strike work there?
The 9234 is a flat T strike sized 2-3/4 inches by 1-1/8 inches, prepped with a single latch hole and made to sit against a standard commercial door frame face. Where the latch has to land on a round post instead, the corresponding part is a pipe adapter strike such as the Trimco 1260P, which is furnished as a strike only in the 1260 Series. Confirm what the latch is striking before ordering: flat jamb face takes the 9234, round pipe takes the 1260P style of adapter strike.
5) Is a T strike or an ANSI strike the right one for a commercial hollow metal frame?
Depends on how the frame was prepped. A T strike like the Don-Jo 9234 is the compact option, 2-3/4 x 1-1/8, and it suits frames prepped for a narrow strike with a single latch hole, cylindrical lock work being the usual case. An ANSI strike is the taller, wider plate used where the frame is prepped to the 4-7/8 inch standard, and it is what mortise locks with a latch and a deadbolt typically need since it carries two holes. The 9234 has one latch hole only, so it will not serve a lock with a separate deadbolt.
6) How strong is the Don-Jo 9234 strike for a high traffic door?
The plate is 16-gauge steel, .062 thick. That is the heavier end of what gets used for a strike plate and it holds its shape under repeated latch impact, which is what you want on a stairwell, a corridor, or a tenant entry that cycles all day. Worth noting the strike is only as strong as what is behind it: on a hollow metal frame the screws land in the frame, and if the previous strike tore out you want to address the frame, not just swap plates.
7) What finishes does the Don-Jo 9234 T strike come in, and which one matches my existing hardware?
Five finishes: 605 polished brass, 622 matte black, 629 bright stainless steel, 630 satin stainless steel, and DU duronodic brown coated. For a fleet of doors already running satin stainless lever sets, 630 is the match, and it is the most common commercial choice. 605 pairs with polished brass trim, 622 with black hardware, and DU with dark bronze anodized aluminum entrances. Match the strike to the lockset on the door, not to the frame paint.
8) I need a strike for an aluminum storefront door, is the Don-Jo 9234 the right part?
Probably not. The 9234 is a commercial T strike sized 2-3/4 x 1-1/8 for a standard frame strike prep. Narrow stile aluminum entrances often need a strike built for that specific condition. The Trimco 1260P is a pipe adapter strike, made for mounting to a tube or pipe rail rather than a flat jamb face, and that is the sort of purpose-built strike to look at when the opening is not a conventional prepped frame.
9) I am standardizing strikes across a building and some openings are single doors and some are pairs. Can one strike cover both?
No single strike covers both conditions. The Don-Jo 9234 is a commercial T strike for a single latch hole, 2-3/4 inches by 1-1/8 inches in 16-gauge (.062) steel, and it comes in 605 polished brass, 622 matte black, 629 bright stainless steel, 630 satin stainless steel, and DU duronodic brown coated so it can be matched to the finish already running through the building. The double door openings need a double door strike kit, and the Detex 92 Strike Kit in the 90 Strike Series is supplied with tamper resistant fasteners for that condition. Count the single door openings and the pairs separately and order to each.
10) How is the Don-Jo 9234 packaged if I am buying strikes for a whole building?
It ships in shelf packs of 30. That works out well if you are standardizing latch strikes across a floor or a property, and it is the reason contractors and distributors tend to buy this one by the pack rather than the piece. Pick your finish first, since each finish is ordered separately.
11) Is the Don-Jo 9234 strike suitable for apartment and residential unit doors?
It is built and specified as commercial hardware, 16-gauge steel construction, and it is used on multi-tenant residential entries, offices, schools, healthcare, retail, warehouse, and government buildings. On a multi-family property with hollow metal unit doors and frames, it fits that use. For an interior wood-jamb residential door with a light stamped strike, the 9234 is heavier than the prep usually accommodates.
