Don-Jo D9104-630 – Frequently Asked Questions

1) Will the Don-Jo D9104 extended lip strike cover the gap left by a wider frame or an out-of-position latch?
That is what the extended lip is for. The D9104 measures 2-1/4 inches by 4 inches, and the 4 inch width is measured from the center of the screw hole to the end of the lip, so the lip runs well past the fastening line to reach across the jamb face and out toward the door. Measure from your existing screw hole centerline to where the lip has to land. If that distance is 4 inches or less, this strike covers it; if it is more, you need a longer lip.
2) Extended lip strike or a double door strike kit, which do I need?
Different problems. An extended lip strike like the D9104 is for a single door in a frame where the lip has to reach out past the screw line to meet the latch. For a pair of doors with no mullion, where the active leaf latches into the inactive leaf, that is a different part, the Detex 92 Strike Kit is a double door strike kit supplied with tamper resistant fasteners. And if the latch is going into a pipe or round post rather than a flat jamb, the Trimco 1260P is a pipe adapter strike.
3) Is the Detex 92 strike kit a substitute for a Don-Jo D9104 extended lip dimple strike?
No, they solve different problems. The Don-Jo D9104 is an extended lip dimple strike, a flat strike plate that mounts in the frame and receives a standard latch bolt. The Detex 92 Strike Kit is a double door strike kit supplied with tamper resistant fasteners, part of the 90 Strike Series, and is intended for a double door opening rather than as a lip strike for a single latch. If you are replacing a damaged or mis-sized lip strike on a frame, the D9104 is the extended lip dimple strike; if you are strike-mounting a double door, the Detex 92 kit is the one built for that.
4) What does the dimple on a Don-Jo D9104 strike do, and does my latch need it?
The dimple is a formed depression at the latch hole. It takes standard latch bolts and spreads the bearing load off the edge of the opening, so the latch is not chewing on a raw stamped hole every cycle. Standard commercial latchbolts drop straight into it. It is not a deadlatch feature, so a deadlocking plunger still needs to ride the strike face the way it does on any flat strike.
5) Is 18-gauge steel heavy enough for a strike on a high-traffic commercial door?
The D9104 is 18-gauge (.050) steel and is built for commercial service, which is the weight typically used on office, school, healthcare, retail and warehouse openings where the door cycles all day. On an opening that gets abused or forced, the strike is only half the answer, a strike box or reinforcer behind it carries the load into the frame.
6) What finishes does the Don-Jo D9104 strike come in, and which matches my existing hardware?
Four finishes: 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For matching a building already standardized on stainless or aluminum lever hardware, 630 is the one that reads correctly. 605 pairs with polished brass trim, DU with dark bronze anodized aluminum storefront and entry hardware, and 622 with black hardware packages.
7) Can I use the Don-Jo D9104 on a round pipe or tube jamb?
No. The D9104 is a flat-face strike with an extended lip for a conventional jamb. Curved pipe or tube framing needs a strike shaped for it, the Trimco 1260P is a pipe adapter strike made for that condition.
8) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo D9104?
The Trimco 1260P is a pipe adapter strike from the 1260 Series, sold as the strike only, and is made to adapt a strike to a pipe or tubular frame condition. The Don-Jo D9104 is an extended lip dimple strike sized 2-1/4 inches high by 4 inches wide, with the width measured from the center of the screw hole to the end of the lip, in 18-gauge (.050) steel. Choose the D9104 when the frame takes a conventional flat lip strike and you need the lip to reach out toward the door face; choose the 1260P when the strike has to land on a pipe frame.
9) Do I have to buy Don-Jo D9104 strikes in a multi-pack?
The D9104 is sold in shelf packs of 10. That works in your favor if you are re-striking a corridor or a floor of units and want every opening the same, but it does mean a single-door repair leaves you with spares.
