Don-Jo T9115-630 – Frequently Asked Questions

1) What size is the Don-Jo T9115 T strike, and how is the 1-1/2 inch measured?
The T9115 measures 2-3/4 inches in height by 1-1/2 inches in width, and that width is taken from the center of the screw hole to the end of the lip, not across the whole plate. That matters when you are checking lip projection past the frame stop: the extended lip is what carries the latch across a gap, so measure from your existing strike's screw hole out to where the lip ends before you decide it drops in. Formed at 18 gauge (.050).
2) Is the Don-Jo T9115 a single latch hole strike or does it have a deadbolt cutout?
Single latch hole only. The T9115 is a T-style strike with one opening for the latchbolt, so if the door has a separate deadbolt you need a second strike for it, or a combination strike with two cutouts. It is the right part when you are replacing a plain latch strike on a cylindrical lockset or a passage/entry set that keeps the deadbolt separate.
3) Can I use the Don-Jo T9115 on a pair of doors with no mullion?
Not on the meeting edge. The T9115 mounts to a door frame jamb, so it works on the hinged leaf of a normal single opening or the strike jamb of a pair with a mullion. For a pair where the active leaf latches into the inactive leaf, you want a double door strike kit such as the Detex 92 Strike Kit, which is built for that condition and comes with tamper resistant fasteners.
4) Is the Detex 92 strike kit a substitute for a Don-Jo T9115 extended lip T strike?
No, they solve different openings. The Don-Jo T9115 is an extended lip T strike with a single latch hole, 2-3/4 inch height by 1-1/2 inch width measured from the center of the screw hole to the end of the lip, formed in 18 gauge (.050) non-ferrous material for a standard latch engagement in a single door frame. The Detex 92 Strike Kit is a double door strike kit supplied with tamper resistant fasteners and belongs to the Detex 90 Strike Series. If the opening is a pair of doors and you are strike-mounting to the inactive leaf, the 92 kit is the one built for it; for a single latch hole in a conventional frame, the T9115 is the T strike form.
5) What strike do I use if the latch has to engage a pipe or round post instead of a flat frame?
That is the Trimco 1260P Pipe Adapter Strike, sold as a strike only and part of the Trimco 1260 Series - the pipe adapter form exists specifically to give a latch a strike surface on round stock. The Don-Jo T9115 is an extended lip T strike, 2-3/4 inch by 1-1/2 inch in 18 gauge non-ferrous material, with the lip extended to carry the latch across to a flat frame face; it has no provision for wrapping a pipe. Match the strike to what the latch is landing on before you match finish.
6) Why would I use an extended lip strike instead of a standard flat strike plate?
An extended lip carries the latch out past the frame face, which is what you want when the frame is set back from the door edge, the stop is thick, or the jamb has been built out with trim or a wood casing. A standard short-lip strike in that situation leaves the latch riding on the frame instead of dropping into the cutout, and the door bounces back open. If your frame sits flush with the door edge and the existing strike lip is short, a standard T strike is the simpler swap.
7) Will the Don-Jo T9115 strike rust in an exterior or humid opening?
The T9115 is made from non-ferrous material, so there is no steel in it to rust. That is the reason to pick it for exterior doors, pool and locker rooms, kitchens, laundry, and coastal buildings where a plated steel strike blooms rust around the screw holes within a season. Non-ferrous also means it is non-magnetic, which occasionally matters near sensitive equipment.
8) What finishes does the Don-Jo T9115 T strike come in, and which matches satin chrome hardware?
Five finishes: 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coating. For satin chrome or brushed nickel lever sets, 630 satin stainless is the standard commercial match and the one most building standards specify. 622 matte black pairs with black lever trim, and DU duronodic is the brown anodized tone used on aluminum storefront and older commercial entrances.
9) Is a T strike the same thing as a pipe adapter strike or a double door strike kit?
No, and they solve different problems. The T9115 is a T-shaped latch strike that mounts to a door frame for a standard latchbolt. A Trimco 1260P pipe adapter strike from the 1260 Series is for mounting a strike to round pipe or tube framing rather than a flat jamb. A Detex 92 Strike Kit from the 90 Strike Series is a double door kit supplied with tamper resistant fasteners, meant for the inactive leaf of a pair. Match the part to the frame you actually have.
10) I need a strike that resists someone backing the screws out - does the Don-Jo T9115 come that way?
The T9115 is fastened conventionally; it is an extended lip T strike in 18 gauge non-ferrous material, which is where its corrosion resistance comes from rather than from the fasteners. If tamper resistance at the fastener is the requirement - a detention-adjacent corridor, an exposed exterior pair, a facility where the strike is reachable from the unsecured side - the Detex 92 Strike Kit is supplied with tamper resistant fasteners as part of the kit and covers a double door opening. Specify by whichever constraint governs the opening: fastener security on the Detex, or the single latch hole T strike profile and finish range on the Don-Jo.
11) Is 18 gauge heavy enough for a T strike on a high traffic commercial door?
The T9115 is formed at 18 gauge (.050) and Don-Jo rates it for commercial use, which covers office corridors, schools, healthcare, retail, and multi-tenant entries. On an opening that gets kicked or forced, the strike is rarely the failure point anyway, the frame reinforcement behind it is. If you have had a jamb split at the strike, the fix is a wrap-around or reinforcing strike box, not a heavier plate.
12) How is the Don-Jo T9115 packaged if I am buying strikes for a whole building?
The T9115 ships in shelf packs of 10, which is convenient if you are standardizing a floor or restocking a maintenance shop, but it means you cannot order a single piece. Buy in tens and keep the balance as spares, since a strike is the part a maintenance tech most often needs on short notice.
13) Can I order the Trimco 1260P and just use the strike plate off it in place of a T9115?
The Trimco 1260P is catalogued as a strike only within the 1260 Series, so there is no separate plate to pull from it - what you receive is the pipe adapter strike itself, shaped for round stock. The Don-Jo T9115 is a different part entirely: a 2-3/4 inch by 1-1/2 inch extended lip T strike, single latch hole, 18 gauge non-ferrous, offered in 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For a flat frame with a standard latch, order the T9115 in the finish that matches the rest of the trim on the opening.
