Don-Jo DEST-103-630 – Frequently Asked Questions

1) Will the Don-Jo DEST-103 strike fit a standard ASA prep in my hollow metal frame?
The DEST-103 is an ASA-profile strike measuring 4-7/8 inches in height, which is the standard ASA (T-strike) frame prep dimension used on commercial hollow metal frames. If your existing strike cutout is the 4-7/8 by 1-1/4 inch ASA prep, this drops into it. If the frame is prepped for a smaller square-corner or round-corner residential strike, it is not a match without reworking the frame.
2) What does the 3 inch dimension on the Don-Jo DEST-103 extended lip strike actually measure?
On the DEST-103 the 3 inch figure is the lip width, measured from the center of the screw hole out to the end of the lip. That is the number that matters if you are trying to bridge a gap between the frame and the door face, or clear a deep frame return or applied stop. It is not the overall plate width. The plate height is 4-7/8 inches.
3) Can I use the DEST-103 on a pair of doors with no mullion?
No. The DEST-103 is a frame-mounted ASA strike, so it needs a frame jamb to mount into. On a pair of doors with no center mullion there is no jamb at the meeting stile, and you need a strike made for that condition instead. ZenSupply carries the Detex 92 Strike Kit, a double door strike kit from the 90 Strike Series supplied with tamper resistant fasteners, for exactly that application.
4) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo DEST-103 ASA strike?
No, they solve different openings. The Don-Jo DEST-103 is an extended lip dimple ASA strike, 4-7/8 inches in height by 3 inches measured from the center of the screw hole to the end of the lip, made from 18-gauge (.050) steel and prepped into a standard ASA frame cutout for a latchbolt. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series and comes with tamper resistant fasteners. If the latch is throwing into a standard ASA frame prep on a single door, the DEST-103 is the ASA-profile strike; if the strike has to be mounted on a double door opening, that is where the Detex 92 kit applies.
5) What should I order if the strike has to land on a round post instead of a flat frame?
Use the Trimco 1260P Pipe Adapter Strike, which is sold as a strike only and belongs to the Trimco 1260 Series. The Don-Jo DEST-103 is a 4-7/8 by 3 inch extended lip dimple ASA strike, sized and prepped for the flat face of a standard commercial door frame, so it is the wrong body for a pipe or post mounting condition. Match the pipe adapter to the post, and keep the DEST-103 for the flat-frame openings on the same job.
6) When do I need an extended lip strike instead of a standard ASA strike?
You need the extended lip when the latch has to travel past something before it reaches the strike: a deep frame return, an applied stop, a thick trim casing, or a door that sits back from the frame face. A standard-lip ASA strike leaves the latch riding on the edge of the frame and the door will not pull up tight. The DEST-103 carries the lip out to 3 inches from the center of the screw hole, which is what closes that gap. If your door face sits flush with the frame face, a standard lip strike is the simpler choice.
7) How heavy is the steel on the Don-Jo DEST-103 strike, and will it hold up in a high-traffic entry?
18-gauge (.050) steel. That is the gauge Don-Jo uses on its commercial strikes, and it is rated commercial rather than residential, so it is intended for office, school, healthcare, retail, and multi-tenant openings where the door cycles all day. The extra body over a thin residential strike is what keeps the lip from deforming when a door gets pulled hard against the latch.
8) Is the Don-Jo DEST-103 the right strike for an aluminum storefront door?
Usually not. The DEST-103 is an ASA strike sized to the 4-7/8 inch prep found in hollow metal and wood commercial frames. Aluminum storefront jambs are narrow tube and are typically prepped for a different strike entirely. For a storefront application where the strike has to land in a pipe or tube jamb, the Trimco 1260P pipe adapter strike is built for that condition. The one place the DEST-103 does suit a storefront is the finish: DU duronodic brown was made to match dark bronze aluminum entrances.
9) Will the Don-Jo DEST-103 work with a cylindrical lockset, or is it only for mortise locks?
Both. The 4-7/8 inch ASA strike opening is the standard commercial strike prep, and cylindrical lever sets and mortise locks with a standard latch bolt both land in it. What decides the fit is the frame prep, not the lock type: if the jamb is cut for a 4-7/8 inch ASA strike, the DEST-103 goes in. A mortise lock with a deadbolt requires a strike with a second opening for the bolt, so check that your existing strike has only the single latch cutout before swapping.
10) I need one strike part number I can standardize on across a building of commercial openings. Which of these is that part?
The Don-Jo DEST-103 is the one written for repeat use across a facility: it is an ASA-profile extended lip dimple strike in 18-gauge (.050) steel, listed for commercial applications, and it comes in 622 matte black, 630 satin stainless steel, and DU duronodic brown coated so one part number covers several hardware finish schedules. The Trimco 1260P is a pipe adapter strike and the Detex 92 is a double door strike kit, so both are condition-specific parts you would stock in small quantity alongside a standard ASA strike rather than in place of one.
11) What is the dimple on the Don-Jo DEST-103 strike for?
The dimple is a shallow depression pressed into the lip below the latch opening. It gives the latch bolt a place to sit as the door swings closed so the bolt is guided into the opening instead of skating across a flat lip. On an opening where the door is slightly out of alignment or the closer is running slow, that is often the difference between the door latching and the door bouncing back. The DEST-103 combines that dimple with the extended 3 inch lip.
12) What finishes does the Don-Jo DEST-103 ASA strike come in?
Three: 630 satin stainless steel, 622 matte black, and DU duronodic brown coated. For matching a building already standardized on stainless lever sets and exit devices, 630 is the one to order. 622 matte black pairs with black hardware packages, and DU is the dark bronze-brown coating used on older aluminum storefront and commercial entrances. Ordering the strike in the same finish as the lock is what keeps a retrofit from looking like a repair.
13) Do I need to specify handing when ordering the Don-Jo DEST-103 strike?
No. The DEST-103 is a symmetrical ASA plate, so the same part serves left and right hand openings. The only choice on the order is finish: 630 satin stainless, 622 matte black, or DU duronodic brown. That makes it straightforward to stock one part number across a building and pull it for whichever door needs it.
