Don-Jo FL-208NM-SL – Frequently Asked Questions

1) Will the Don-Jo FL-208NM strike cover the old mortise cutout in my frame?
The FL-208NM is an 8 x 1-3/8 inch face, so it covers a tall section of the jamb and hides the wear and chewed-up edges left by a previous strike or an ANSI-size prep. Anything wider than 1-3/8 inches in the frame will still show at the sides, so measure the width of the existing cutout before you order. It carries a single latch hole, which means one latchbolt, not a latch plus deadbolt.
2) Is the Don-Jo FL-208NM strong enough for a high-traffic commercial entry that keeps getting kicked?
It is built from 13-gauge (.095) ferrous stock, which is heavy plate compared with the thin strikes packed with most cylindrical locks. The height of the face, 8 inches, spreads a forced-entry load over more of the jamb than a short 4-7/8 inch strike does, so more screws are catching more frame. That is the point of a security strike: reinforce the weakest part of the opening.
3) Does the FL-208NM security strike work with a deadbolt as well as the latch?
No. One latch hole only, so it serves a single latchbolt. If the opening has a lockset and a separate deadbolt, you need a two-hole strike or a separate strike for the deadbolt.
4) Will a Detex 92 strike kit work in place of a Don-Jo FL-208NM security strike?
They solve different problems. The Don-Jo FL-208NM is a security strike for commercial doors, 8 inches tall by 1-3/8 inches wide, formed from 13-gauge (.095) ferrous material with a single latch hole, so it takes a standard latch bolt on a frame. The Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series supplied with tamper resistant fasteners, which is what you reach for on a pair of doors where the strike lands on the inactive leaf rather than on a frame. If the opening is a single door with a conventional latch, the FL-208NM is the strike that fits; if you are striking a double door, the Detex 92 kit is the one built for it.
5) What finishes does the Don-Jo FL-208NM come in, and which one should I use on a painted steel frame?
Two finishes are offered on the FL-208NM: BP brass plated and SL silver coated. On a painted hollow metal frame most people run the silver coated version, since it disappears against a gray or primed jamb and takes paint if you want to match the frame color. Brass plated is the one to pick when the surrounding trim is brass.
6) Will the FL-208NM strike work on a pair of doors with no mullion?
No. The FL-208NM mounts in the frame jamb and takes a single latchbolt, so it is a single-door part. For a double door you want a strike built for that condition, such as the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners.
7) What is the difference between a Don-Jo FL-208NM and a Trimco 1260P strike?
The Don-Jo FL-208NM is a full-height security strike, 8 inches by 1-3/8 inches in 13-gauge (.095) ferrous material with one latch hole, meant to reinforce a commercial door frame along a long section of the jamb. The Trimco 1260P is a pipe adapter strike, supplied as the strike only, and it is the piece used where the latch has to strike a pipe or tubular section rather than a flat jamb face. Match the part to what the latch is landing on: flat commercial frame takes the FL-208NM, a pipe application takes the 1260P from the Trimco 1260 Series.
8) Is the FL-208NM rated for commercial use or is it a residential part?
Commercial. Don-Jo lists the FL-208NM as a commercial product, and the 13-gauge ferrous body is heavier than what you find on residential strikes. It is the kind of part that goes into office buildings, schools, healthcare, retail, and multi-tenant housing where the door cycles all day.
9) I need to standardize strikes across a building. Can I buy the FL-208NM in bulk?
It ships in shelf packs of 10, which suits a property manager or contractor changing out strikes on a run of openings rather than a single door. Same 8 x 1-3/8 inch face on every one, so the prep is identical door to door once you have set the first one.
10) Can I paint or weld the Don-Jo FL-208NM strike to match the frame?
The body is ferrous, so it is magnetic steel and takes primer and paint the same way a hollow metal frame does. Bear in mind the BP and SL versions are plated or coated finishes, so scuff and prime before topcoat if you want paint to hold.
11) I need tamper resistant fasteners with my strike - does the Don-Jo FL-208NM come that way?
The Don-Jo FL-208NM is a 13-gauge (.095) ferrous security strike in 8 inch by 1-3/8 inch, offered in BP - Brass Plated and SL - Silver Coated, and its security comes from the heavy-gauge plate itself spreading force along the jamb. Where the specification calls out tamper resistant fasteners as part of the strike package, the Detex 92 Strike Kit is supplied with them for double door openings. On a single door, many buyers pair the FL-208NM plate with security fasteners specified separately for the frame.
