Don-Jo T9125-630 – Frequently Asked Questions

1) What size is the Don-Jo T9125 T strike, and how is the 2-1/2 inch width measured?
The T9125 measures 2-3/4 inches in height by 2-1/2 inches in width, and the 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 whether the lip will reach past the stop to the face of the door. Measure your frame the same way before you compare it to what you have in the jamb now.
2) Can a Trimco 1260P be used in place of a Don-Jo T9125 extended lip T strike?
No — they solve different problems. The Don-Jo T9125 is an extended lip T strike for commercial doors, 18 gauge (.050) non-ferrous, 2-3/4 inch height by 2-1/2 inch width measured from the center of the screw hole to the end of the lip, with a single latch hole for a standard commercial latch bolt in a prepped door jamb. The Trimco 1260P is a pipe adapter strike from the 1260 series, intended for a pipe or tubular frame condition rather than a flat jamb face. If the opening is a conventional jamb taking a latch bolt, the T9125 is the strike; the 1260P is for the pipe-frame case.
3) Why would I use an extended lip strike instead of a standard T strike?
An extended lip carries the latch ramp further out from the frame, so it covers the gap where a deep stop, an applied stop, or thick jamb trim would otherwise leave the latch bearing on the wood or drywall as the door closes. The T9125 is the extended lip version of the T strike, with a single latch hole for a standard commercial latchbolt. If your jamb face is flush with the door and the latch already lands clean on a standard strike, you do not need the extra lip.
4) Is the Don-Jo T9125 strike heavy enough for a high-traffic commercial opening?
It is built at 18 gauge (.050) and rated for commercial use, which is the thickness you want on an entry, corridor, or classroom door that cycles all day. Thinner residential strikes deform at the lip after repeated latch strikes; this one is a full 18 gauge plate. Non-ferrous material keeps it from rusting at exterior or wash-down openings.
5) Will the T9125 strike rust on an exterior or wet-area door?
No. The T9125 is made from non-ferrous material, so it does not rust the way a plated steel strike does at an exterior jamb, a pool or locker room door, or a kitchen. That is the reason to pick it over a standard steel strike for openings that see moisture.
6) Is the T9125 a replacement for the strike on a rim exit device?
No. The T9125 is a lip strike for a standard commercial latchbolt with one latch hole, which is a cylindrical or mortise latch in a jamb. Exit devices take their own strike. For a rim device on a pair, look at the Detex 92 Strike Kit from the 90 Strike Series, and where a pipe or round post has to receive the latch, the Trimco 1260P Pipe Adapter Strike is the part that handles that condition.
7) I need a strike with tamper resistant screws for a high abuse opening — is the T9125 the right choice?
The Don-Jo T9125 is a commercial 18 gauge (.050) non-ferrous extended lip T strike whose extended lip profile gives added latch capture on a standard jamb. Where the requirement is specifically fastener security at a pair of doors, the Detex 92 Strike Kit is supplied with tamper resistant fasteners. Match the choice to the opening first: the T9125 for a single latch bolt into a frame, the Detex kit for the double door center condition where tamper resistant fasteners are called for.
8) What finishes does the Don-Jo T9125 strike come in?
Five: 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless, and DU duronodic brown coated. For matching existing openings, 630 is the standard commercial pairing with satin stainless levers and exits, and DU is what you order when the building's aluminum storefront and door hardware are dark bronze.
9) I need strikes for a whole building, how does the T9125 come packaged?
It is sold in shelf packs of 10, which is how you would stock it for a re-key or a corridor-wide hardware refresh rather than buying strikes one at a time. Ordering one finish across the pack keeps every opening matching.
