Don-Jo 9125-630-RC – Frequently Asked Questions

1) Will the Don-Jo 9125-RC extended lip strike cover the gap where my frame is set back from the door face?
That's exactly what the extended lip on the 9125-RC is for. The 2-1/2 inch width is measured from the center of the screw hole out to the end of the lip, so the lip reaches well past the frame face to carry the latch across a wider gap than a standard strike lip. The plate itself is 2-1/4 inches high. Measure from your screw hole centerline to where the latch needs support; if that distance is under 2-1/2 inches, the lip covers it.
2) Radius corner or square corner strike, which one do I need for my door frame?
Match the corner to the frame prep already cut in your jamb. The 9125-RC has a radius corner profile, which drops into the rounded-corner cutouts found in most hollow metal commercial frames. If your existing strike has square corners, a radius plate will leave a small gap at each corner of the mortise and won't sit flush. Pull the old strike and look at the corners of the cutout before ordering.
3) Is the Don-Jo 9125-RC a single latch strike or will it take a deadbolt too?
Single latch hole only. The 9125-RC is cut with one opening for the latchbolt, so it serves a knob, lever, or a latch-only function. If your door has a separate deadbolt above the lockset, that bolt needs its own strike, or you need a combination plate with two openings.
4) I need a strike for a pair of doors with no mullion, will an extended lip strike work?
No. The 9125-RC is a single-leaf strike with one latch hole that mounts in the jamb. A pair of doors without a mullion latches into the inactive leaf, not the frame, so it needs a strike built for that condition. The Detex 92 Strike Kit, from the 90 Strike Series, is a double door strike kit and is the right direction for that opening.
5) What strike should I use on a pair of doors instead of an extended lip strike?
An extended lip strike like the Don-Jo 9125-RC mounts to a frame jamb and captures a latch bolt at a single latch hole, which is the arrangement on a single door in a prepped frame. A pair of doors has no jamb on the strike side, so the hardware there is a different part: the Detex 92 Strike Kit is built for double door openings and comes with tamper resistant fasteners, which matters on an opening where the strike face is reachable from both leaves. If the opening is a pair, order against the double door kit rather than sizing a lip strike to it.
6) Is a pipe adapter strike the same thing as an extended lip strike?
No. The Trimco 1260P is a pipe adapter strike, sold as the strike only, and it is made to adapt a latch to a pipe frame rather than to a flat prepped jamb. The Don-Jo 9125-RC is an extended lip strike, 2-1/4 inch height by 2-1/2 inch width with the width measured from the center of the screw hole to the end of the lip, in 18-gauge (.050) steel with a radius corner profile for standard commercial frame preparations. The two get confused because both are called strikes, but the frame each one lands on is different, so confirm what the latch is striking into before you substitute one for the other.
7) How heavy a gauge is the Don-Jo 9125-RC strike plate?
18-gauge steel, .050 inch thick. That's the weight this extended lip strike needs to keep the lip from deflecting when a door gets pulled shut hard on a spring closer, which is the usual failure on a long-lip strike in a school corridor or an apartment entry.
8) What finishes does the Don-Jo 9125-RC come in for matching the rest of my door hardware?
Eight finishes: 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. For a fleet of doors, 630 satin stainless is the one that matches most commercial lever and cylindrical hardware; 622 matte black matches current dark trim packages.
9) Can I use the Don-Jo 9125-RC on a glass storefront door with a pipe or round post frame?
Not a fit. The 9125-RC is a flat plate meant for a flat jamb face with a mortised cutout behind it. A round pipe post or tubular frame needs a strike shaped to that curve, such as the Trimco 1260P pipe adapter strike from the 1260 Series. Bending a flat 18-gauge plate around a post throws the latch alignment off.
10) I need to match the strike finish across a floor of doors - what are my options?
The Don-Jo 9125-RC extended lip strike is the finish-flexible choice of the strikes in play: it is stocked in 605 polished brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless steel, 630 satin stainless steel, and DU duronodic brown coated. Neither the Detex 92 double door strike kit nor the Trimco 1260P pipe adapter strike is a finish-matching part in the same way - they are selected by the opening type they serve, the 92 for double doors and the 1260P for pipe frames. If your driver is a consistent look across a run of single doors in prepped frames, standardize on one 9125-RC finish and carry it through the floor.
11) Do I have to buy the 9125-RC strike one at a time or in a box?
Shelf packs of 10. That suits a property manager or maintenance shop replacing strikes across a run of units, or a contractor doing a floor of offices at once. Order the pack in a single finish so every opening matches.
12) Is the Don-Jo 9125-RC rated for commercial traffic or is it a residential strike?
Commercial. Don-Jo builds the 9125-RC for commercial door hardware use, and the 18-gauge (.050) steel body is what carries it through office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and municipal buildings.
