Don-Jo AST-2134M-SL – Frequently Asked Questions

1) Will the Don-Jo AST-2134M security strike cover the mortise latch on my commercial frame?
The AST-2134M is an 18 inch by 1-3/4 inch strike plate with a single mortise latch hole, so it suits a frame prepped for a mortise lock latch rather than a cylindrical latch. The long 18 inch face runs well above and below the latch point, which is what gives you the reinforcement against spreading the frame or kicking the door. If your opening has a cylindrical (bored) lockset, the mortise cutout will not line up with your latch.
2) Is the Detex 92 strike kit an equivalent to the Don-Jo AST-2134M security strike?
They solve different problems even though both are called strikes. The Don-Jo AST-2134M is a full-height frame reinforcement, 18 inches tall by 1-3/4 inches wide in 13-gauge (.095) ferrous material, with a single mortise latch hole, so it covers and reinforces the strike area of the frame around a mortise lock. The Detex 92 strike kit is a double door strike kit supplied with tamper resistant fasteners, so it is the strike hardware for a pair of doors rather than a length of frame armor. On a single opening with a mortise lock where the frame is chewed up or has been pried, the AST-2134M is the piece that goes on; on a double door application the 92 kit is the one addressing that condition.
3) Can a Trimco 1260P be used in place of a Don-Jo AST-2134M?
No, they are not interchangeable. The Trimco 1260P is a pipe adapter strike, supplied as the strike only, from the 1260 series - it adapts a latch to a pipe or tubular frame condition. The Don-Jo AST-2134M is a mortise-hole security strike, 18 inches by 1-3/4 inches in 13-gauge (.095) ferrous material, meant to armor the strike edge of a commercial frame against spreading and kick-in. If the opening is a pipe or tubular frame, the 1260P is the part that fits it; if it is a standard commercial frame with a mortise lock that needs reinforcement, the AST-2134M is the one to order.
4) How heavy is the metal on the Don-Jo AST-2134M strike, and is it strong enough for a high traffic entry?
Ferrous construction at 13-gauge, .095 inch thick. That is a solid plate rather than a light cover, which is why it holds up on commercial entries taking constant use and why it resists the kind of prying and kick force that opens a thin strike. Substrate is ferrous, so it will take a magnet and it will rust if left uncoated, which is what the finish options are for.
5) What finishes does the Don-Jo AST-2134M come in, and which one do I pick to paint it?
Three finishes: BP brass plated, SL silver coated, and WH white coated. BP (prime coat) is the one to take if the frame is getting painted, since it takes topcoat. SL blends with the aluminum and stainless frames on most storefront and institutional openings, and WH matches painted white hollow metal frames in apartments and offices without any touch-up.
6) I manage a building and need to reinforce a lot of doors. How is the AST-2134M sold?
Shelf packs of ten. That works in your favor if you are standardizing a run of apartment or office entries: one finish, one pack, and every door in the corridor gets the same 18 inch strike. If you only have a single door to fix, you are still buying the pack.
7) Do I need a security strike like the AST-2134M, or a strike box or double door strike kit instead?
An 18 inch security strike is the answer when the weak point is the frame itself and the door swings on a single opening with a mortise lock: the long plate spreads the load across the jamb. It is not the part for a pair of doors with no mullion, where the active leaf latches into the inactive one. For that, a double door strike such as the Detex 92 Strike Kit, which includes tamper resistant fasteners, is the correct type. Different job, not a better or worse plate.
8) Can I use the Don-Jo AST-2134M with a rim exit device or a pipe rail?
No. The AST-2134M is cut for a mortise latch, so a rim device latch or a pipe rail application needs a different strike entirely. For a strike that adapts to pipe, the Trimco 1260P Pipe Adapter Strike is the part built for that, sold as the strike only.
9) For a door that keeps getting pried at the latch, which strike should a property manager standardize on?
For repeated pry damage at the latch on commercial frames running mortise locks, the Don-Jo AST-2134M is the one to carry: 18 inches of 13-gauge (.095) ferrous coverage in a 1-3/4 inch width, with a single mortise latch hole, and it is sold in shelf packs of 10 in BP prime coat, SL silver, and WH white so a whole building can be brought to one look. Of the alternatives, the Detex 92 strike kit covers double door openings and ships with tamper resistant fasteners, and the Trimco 1260P handles pipe frame conditions - so a mixed property may need one of those for the specific openings that are not standard single doors with mortise locks.
10) Is the Don-Jo AST-2134M a residential product or a commercial one?
Commercial. The AST-2134M is built for hollow metal and commercial frames in offices, schools, healthcare, retail, warehouses, apartment buildings, and government facilities. On a residential wood jamb an 18 inch, 13-gauge ferrous plate is far more strike than the frame is prepped for.
