Don-Jo EL-104-622-RC – Frequently Asked Questions

1) What does the 4 inch dimension on the Don-Jo EL-104-RC extended lip strike actually measure?
On the EL-104-RC, the 4 inch figure is measured from the center of the screw hole to the end of the lip, not the overall plate length. The plate face is 2-1/4 inches. That matters because the lip length is what carries the latch across the gap between a recessed frame and the door face, so if you are sizing to cover a deep reveal, measure from your existing screw hole center out to where the latch needs to land, not the whole strike.
2) When do I need an extended lip strike instead of a standard ANSI strike?
An extended lip strike like the EL-104-RC is what you use when the frame is set back from the door face, or the jamb is wrapped in drywall or trim, and a standard short lip leaves the latch to catch on the casing instead of riding into the pocket. The extended lip carries the latch over that reveal. If the door and frame sit flush and the latch already enters cleanly, a standard strike does the job and the longer lip only adds something to snag on.
3) Will the Don-Jo EL-104-RC drop into an existing radius corner frame prep?
The RC in EL-104-RC is the radius corner profile, which is the rounded-corner cutout used on most hollow metal commercial frames. If the existing strike in your jamb has rounded corners, this one matches that prep. If the pocket in your frame is squared off at the corners, this will leave a gap at each corner and you want a square corner strike instead.
4) Is one strike enough for a deadbolt and a latch, or do I need two?
One. The EL-104-RC has a single latch hole, so it handles one bolt. On a door with both a cylindrical latch and a separate deadbolt you need either two strikes or a single T-strike with two openings. Ordering one of these for a two-bolt opening leaves the deadbolt with nowhere to go.
5) Is 18 gauge steel heavy enough for a strike on a high traffic commercial door?
The EL-104-RC is 18 gauge (.050) steel, which is the working thickness for commercial strikes in offices, schools, healthcare, retail and multi-tenant buildings. On an opening that gets kicked or pried, the strike is rarely the weak point anyway. The frame behind it is, so the strike box and the anchoring into the jamb decide how much abuse the opening takes.
6) I need a strike for a pair of doors with no mullion, will this one work?
No. The EL-104-RC mounts in the jamb and serves one leaf latching into the frame. On a pair of doors where the active leaf latches into the inactive one, you need a strike made for that condition. For double door exit device applications, the Detex 92 Strike Kit is built for double doors and comes with tamper resistant fasteners.
7) Can I use this strike on a round post or pipe instead of a door frame?
No. The EL-104-RC is a flat plate strike for a standard jamb face. Mounting it on a round column or pipe gate post leaves it rocking on the curve with the screws pulling at an angle. For that condition, the Trimco 1260P pipe adapter strike from the 1260 Series is the part made for it.
8) What finishes does the Don-Jo EL-104-RC extended lip strike come in?
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 openings, the two that come up most in commercial work are 630 satin stainless, which matches the great majority of Grade 1 lever and lock trim, and 622 matte black on newer storefront and multi-family jobs. The strike sits in the jamb and only the lip and face are visible, so matching the lockset finish rather than the door is the call.
9) Do I have to buy Don-Jo EL-104-RC strikes in a box of 10?
The EL-104-RC is packed in shelf packs of 10. For a property manager standardizing a floor of doors or a contractor working a punch list, that lands about right. For a single door repair you will have nine spares, which is not the worst outcome on a part that gets lost in a van.
