Don-Jo DON-DL 12-63 – Frequently Asked Questions

1) Will a Don-Jo DL 12 double lip strike cover the old strike cutout in my frame?
The DL 12 measures 2-3/4 x 6-3/4 inches, so it covers a good deal more frame face than a standard 1-1/4 x 4-7/8 inch ANSI strike. If you are replacing a smaller strike that has been chewed up or drilled out, the larger plate hides the damage as long as the new screw holes land in solid frame. Measure the existing prep first: 6-3/4 inches of length needs clearance above and below the latch pocket, which is not always there on a frame with a short strike jamb reinforcement.
2) What is a double lip strike for, and do I need one instead of a standard strike?
A double lip strike has a lip on both sides of the latch opening rather than one. That matters where a single lip would sit wrong: doors in pairs, openings where the frame is rabbeted on both sides, or a jamb where you want the lip to protect the frame edge on either hand. If your opening is an ordinary single door swinging one way into a hollow metal frame, a standard single lip strike does the job and is the simpler part to order. The DL 12 is the answer when the geometry of the opening puts the latch between two faces you need to protect.
3) Does the Don-Jo DL 12 strike work with a deadbolt as well as a latch?
One hole only. The DL 12 is a single latch hole strike, so it accepts the latchbolt and nothing else. If your lockset is a mortise lock with a separate deadbolt, or a knob plus a separate deadbolt using one common strike plate, you need a two hole strike or a separate deadbolt strike. Count the bolts on your existing hardware before ordering this one.
4) I need a strike for a pair of doors with no mullion. Is the Don-Jo DL 12 the right part?
Not for that. A pair of doors with an exit device on the active leaf needs a strike matched to that device, not a lip strike for a latchbolt. Detex sells a 92 Strike Kit from its 90 Strike Series built for double door applications and supplied with tamper resistant fasteners, which is the direction to go on an exit device pair. The DL 12 is a lip strike for a conventional lockset latchbolt.
5) My frame is round pipe, not a flat jamb. Can I mount the DL 12 on it?
No. The DL 12 is a flat plate and needs a flat frame face to seat against. For a round post or pipe frame, Trimco makes the 1260P Pipe Adapter Strike from its 1260 Series, which is the strike built for that condition. Trying to force a flat lip strike onto a curved surface leaves a gap behind the plate and the latch will not seat consistently.
6) What is the difference between the Don-Jo DL 12 double lip strike and the Detex 92 strike kit?
They solve different problems on the frame. The Don-Jo DL 12 is a double lip strike, 2-3/4 inch by 6-3/4 inch, with a single latch hole and a 13-gauge (.095) non-ferrous body in a 630 stainless finish - it is the strike plate a standard commercial latch throws into. The Detex 92 Strike Kit is part of the Detex 90 Strike Series and is a double door strike kit supplied with tamper resistant fasteners, intended for a pair of doors rather than a single latch opening. If you are replacing a worn strike on one leaf with a conventional lockset, the DL 12 is the direct part; if the opening is a double door assembly needing a kit with security fasteners, the Detex 92 is the one that matches the condition.
7) Can I use a Trimco 1260P instead of a Don-Jo DL 12 double lip strike?
Not as a like-for-like swap. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series and is supplied as the strike only - it is built to suit a pipe or tubular frame condition. The Don-Jo DL 12 is a flat double lip strike measuring 2-3/4 inch by 6-3/4 inch with one latch hole, sized to a standard commercial frame strike preparation. Choose the DL 12 when the frame is prepped for a conventional lip strike and the DL 12 footprint covers the existing cutout; choose the 1260P when the opening is the pipe adapter condition it is designed around.
8) Is the Don-Jo DL 12 strike heavy enough for a high traffic entrance?
The DL 12 body is 13-gauge, .095 inch thick, which is substantially heavier than the thin stamped strikes that ship with residential locksets. That thickness is what resists deformation when a latch is slammed into it thousands of times or when someone leans on the door. On a high traffic commercial opening, a school corridor or an apartment building entry, gauge is the spec that decides whether the strike stays flat in the frame.
9) Will the Don-Jo DL 12 rust in an exterior or wet location?
The DL 12 is non-ferrous with a 630 satin stainless finish, so it holds up in exterior entries, pool and locker rooms, kitchens, and coastal buildings where a plated steel strike would bleed rust into the frame paint. 630 is the standard commercial stainless finish, so it matches the exit devices, push plates, and hinges already specified in most commercial openings.
10) Can I standardize on the Don-Jo DL 12 across a whole building?
For openings that share the same condition, yes, and that is a common way to buy it. The DL 12 ships in one configuration, 630 stainless, single latch hole, 2-3/4 x 6-3/4 inches, so there is nothing to specify per door and no handing to track. The limit is the openings themselves: doors with a separate deadbolt, exit device pairs, and non-flat frames each need a different strike, so survey the building by condition rather than by door count.
11) Is the Don-Jo DL 12 strike handed?
No handing to specify. The double lip layout puts a lip on each side of the latch opening, so the same part serves either swing. That is one of the practical reasons to carry a double lip strike on a service truck: one part number covers openings you would otherwise have to hand.
12) Which commercial strike should I standardize on across a facility with single doors and door pairs?
Split it by opening type rather than trying to force one part onto both. Single-leaf commercial openings with a conventional latch take the Don-Jo DL 12 double lip strike - 2-3/4 inch by 6-3/4 inch, single latch hole, 13-gauge (.095) non-ferrous body, 630 stainless finish, so the same part number repeats across every standard door in the building. Door pairs are the exception: the Detex 92 Strike Kit in the 90 Strike Series is a double door kit and ships with tamper resistant fasteners. Two part numbers cover the whole facility, and the 630 stainless on the DL 12 keeps the visible plates consistent across the single-door count.
13) What finish does the Don-Jo DL 12 double lip strike come in?
630 satin stainless steel is the only finish the DL 12 is built in, so there is no finish decision to make when ordering. If the rest of the opening is 626 satin chrome, the two read very close side by side on a frame, which is why 630 is commonly used on commercial jambs alongside 626 trim.
