Don-Jo 9102-630 – Frequently Asked Questions

1) What is an extended lip strike like the Don-Jo 9102 used for?
An extended lip strike is what you use when the latch has to reach past the frame face to catch, which is common on doors set back in a deep or wide jamb, on frames with a heavy stop, or where the door is offset from the strike prep. The lip runs long so the latch bolt rides up it and seats instead of hanging on the frame edge. The 9102 is an extended lip strike with a single latch hole, so it takes one standard latch bolt, not a deadbolt plus latch. If your latch is already seating cleanly on a standard ANSI strike, you don't need the extended lip.
2) What size is the Don-Jo 9102 strike, and how is the lip length measured?
The 9102 measures 2-1/4 inches in height by 2 inches in width, and the width figure is the one people get wrong. It is taken from the center of the screw hole to the end of the lip, not across the whole plate. So if you are checking whether the lip reaches your latch, measure from your existing strike's screw hole center out to where the latch needs to land and compare against that 2 inch figure.
3) Should I order the square corner or radius corner version of the Don-Jo 9102?
Match the corner to the frame prep you already have. Radius corners are a configuration option on the 9102, and they are what you want when the existing cutout in the jamb has rounded corners, which is typical of hollow metal frames prepped at the factory. If the mortise in your frame is square cut, the square corner version drops in and the radius version will leave a visible gap at each corner. Pull the old strike and look at the pocket before you order.
4) Will the Don-Jo 9102 work on a pair of doors with no mullion?
No. The 9102 is a single latch hole strike that mounts to the frame jamb, so it needs a frame or mullion to fasten to. For a double door application where the latch catches the inactive leaf, look at a purpose-built double door strike such as the Detex 92 Strike Kit, which is made for double doors and comes with tamper resistant fasteners.
5) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo 9102 extended lip strike?
No - they solve different openings. The Don-Jo 9102 is an extended lip strike for a single latch bolt, with one latch hole and a lip whose 2 inch width is measured from the center of the screw hole to the end of the lip, so it catches a latch coming across the gap on a standard commercial 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. Use the Detex 92 kit where a pair of doors needs a strike mounted at the meeting stile and the fasteners have to resist tampering; use the Don-Jo 9102 where a single door latch needs a longer lip to reach the latch on a frame that sits back from the door.
6) The frame on my job is a pipe rail, not a flat jamb - will a Don-Jo 9102 work there?
No. The Don-Jo 9102 is a flat extended lip strike in 18-gauge (.050) steel that mounts to a conventional frame face and needs a flat surface behind it. For a round pipe upright, the strike made for that condition is the Trimco 1260P Pipe Adapter Strike from the Trimco 1260 Series, sold as the strike only. Match the strike to the frame profile first, then match the finish - the 9102 is offered in 605 polished brass, 609 antique brass, DU duronodic brown coated, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless steel, and 630 satin stainless steel.
7) Is the Don-Jo 9102 strike heavy enough for a school or hospital door?
It's built from 18-gauge (.050) steel and specified as commercial rather than residential, which is the gauge you want on openings that see constant traffic. Don-Jo lists it for office buildings, schools, healthcare, retail, industrial, multi-tenant residential and government facilities. On a high-abuse door the strike is rarely the failure point at this gauge; the latch and the frame prep are.
8) What finishes does the Don-Jo 9102 come in, and which one matches my existing hardware?
Eight finishes, all standard BHMA numbers: 605 polished brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless, 630 satin stainless, and DU duronodic brown coated. For a building already standardized on satin chrome levers, 630 satin stainless is the usual visual match. If the doors are older brass, 605 goes with polished trim and 609 with the darker antiqued sets. Buy by the BHMA number off your existing lock, not by the name.
9) Can I use the Don-Jo 9102 with a deadbolt as well as the latch?
Not on one plate. The 9102 has a single latch hole, so it handles the latch bolt only. If the door has a separate deadbolt you need a second strike for it, or a T-strike or ASA strike prepped for both. Check what the frame is cut for before you order, since a two-hole prep will show through around a single-hole plate.
10) What is the difference between the Don-Jo 9102 extended lip strike and a pipe adapter strike?
They solve different problems. The 9102 is a flat extended lip strike for a standard jamb, 18-gauge steel, 2-1/4 by 2 inches. A pipe adapter strike like the Trimco 1260P from the 1260 Series is for mounting a strike to round pipe or tubular framing, where there is no flat jamb face to screw into. If your opening is a glass storefront on a tube frame or a gate post, the flat plate is the wrong part.
11) What strike should I use on a double door pair instead of an extended lip strike?
For a pair of doors, look at the Detex 92 Strike Kit, a double door strike kit that ships with tamper resistant fasteners and is part of the Detex 90 Strike Series. The Don-Jo 9102 is built for a single latch: it has one latch hole and an extended lip in 18-gauge (.050) steel, sized 2-1/4 inch high by 2 inch wide. If the opening is an active and inactive leaf rather than a door and frame, the double door kit is the one dimensioned for that condition.
12) I need a drop-in strike replacement for a standard commercial single door - is the Trimco 1260P a substitute?
The Trimco 1260P is a pipe adapter strike sold as the strike only, from the Trimco 1260 Series, so it is intended for an adapter application rather than a standard frame face. For a straightforward single door latch on a commercial frame, the Don-Jo 9102 extended lip strike is the direct-fit part: one latch hole, 2-1/4 inch height by 2 inch width taken from the center of the screw hole to the end of the lip, radius corners available for frames prepped with a rounded cutout, and 18-gauge (.050) steel. If your existing cutout has square corners, order the square corner configuration; if it is rounded, order the radius corner option.
13) I need strikes for a whole building of doors. How does the Don-Jo 9102 ship?
Shelf packs of 10. That suits the way property managers and contractors actually buy strikes, one pack covers a corridor or a floor and leaves spares on the shelf. If you are standardizing a facility, order the same finish and same corner style across the run so a replacement pulled from stock two years from now still matches.
