ROFU 3403 Fail Safe Electric Strike, Hollow Metal/Aluminum/Wood Frame, Faceplate Size 1-1/4" x 6-7/8"

No handing to specify. The 3403 is reversible and non-handed, so one part covers either swing. That makes it easier to stock as a spare across a building with mixed door swings.

Fail safe means the strike unlocks when power is removed. Cut power or drop the building supply and the door can be pushed open from the outside. That suits egress paths and doors on a fire alarm release, but it is the wrong choice for a door that must stay secure during an outage, such as a stockroom or exterior entry. For those, use a fail-secure strike like the Von Duprin 6210 or the SDC 15 Series. If you want the choice made in the field, the Hager 2925 is field reversible fail safe/secure.

Hollow metal, aluminum, and wood frames all take the 3403. The faceplate is anodized aluminum and measures 1-1/4 by 6-7/8 inches, so the jamb needs to be cut or prepped for that longer plate. If your existing prep is the common 4-7/8 inch ANSI cutout, this one will not drop in without enlarging it, and an Adams Rite 7170 for hollow metal and wood jambs uses the 1-1/4 x 4-7/8 inch size instead.

No. A fail safe strike unlocks on loss of power, which is not acceptable on a fire door that must stay latched. For a fire rated opening, choose a fire rated strike such as the Camden CX-ED1410/CX-ED1420 universal Grade 1 fire-rated strikes, the Hager 2930, or the Von Duprin 6400, which carries a 3-hour UL 10C rating in fail-secure.

The ROFU 3403 is a fail-safe electric strike for hollow metal, aluminum or wood frames with a 1-1/4" x 6-7/8" faceplate and a keeper that accepts up to 5/8" latch projection. For a fire-rated opening, the SDC 45F Series is a fire-rated electric strike that also works with a 5/8" latchbolt and uses a radius corner faceplate, and the Hager 2930 is a fire-rated Grade 1 electric strike for cylindrical and mortise locks with 12/24VDC dual voltage, matching the 12 VDC and 24 VDC coil choices offered on the 3403.

The ROFU 3403 uses a 1-1/4" x 6-7/8" faceplate, so a frame cut for the shorter ANSI prep would need to be extended. For an existing 4-7/8" prep, the Adams Rite 7170 is made for hollow metal and wood jambs with a 1-1/4" x 4-7/8" faceplate, the Adams Rite 7100 covers aluminum jambs with a flat 1-1/4" x 4-7/8" faceplate, and the Dortronics 3300 Series comes with a strike plate for ANSI prep at 4-7/8" x 1-1/4" plus a latch bolt sensing switch and 12/24VDC operation.

The ROFU 3403 is built into hollow metal, aluminum or wood frames with a 1-1/4" x 6-7/8" faceplate and a keeper for latchbolts, so it is not the part for a gate or a rim device. For an outdoor gate, the Camden CX-ED1959 Series is an outdoor rated electric gate strike. For a rim exit device, the Hager 2945 is a fire rated rim exit strike with field selectable fail safe/fail secure and latchbolt monitoring, and for surface vertical rods the HES Folger Adam 310-4-2 is a complete strike pac.

The ROFU 3403 is supplied in 12 VDC and 24 VDC coils. For an AC supply, the Trine 004 runs 8-16VAC, fail secure, with a 6-1/4" x 1-3/8" faceplate and up to 5/8" throw, and the Trine 4300CC runs 16-24VAC/DC, fail secure, with a 5-7/8" x 1-1/4" faceplate and up to 5/8" throw. Both are fire rated and fail secure rather than fail safe.

Two voltages, 12 VDC and 24 VDC, and two finishes, 613 oil rubbed bronze and 628 clear anodized. Voltage is fixed at the time of order rather than field selectable, so match it to your access control power supply before you buy. If you need one strike that covers both voltages, the Dortronics 3300 Series is listed as 12/24VDC.

The ROFU 3403 is a commercial fail-safe strike with an anodized aluminum faceplate for hollow metal, aluminum or wood frames. Lighter-duty choices include the Trine 001 Series, a fail-secure light commercial strike with a 5-7/8" x 1-1/4" faceplate, the RCI 15BS economy strike for special offset latch entry with fail-secure operation, and the SDC 15 Series value strike for 5/8" latchbolts with 12/24 VDC operation. Note that these three are fail-secure rather than fail-safe.

The ROFU 3403 is a fail-safe strike offered in 12 VDC and 24 VDC with a reversible non-handed keeper. Where latch status has to report back to the access control panel, the Dortronics 3300 Series includes a latch bolt sensing switch with 12/24VDC operation, the Hager 2945 includes a latchbolt monitor, and the Camden CX-ED1799L-8 is a Grade 1 dual monitor strike supplied with eight faceplates.

The ROFU 3403 is a single faceplate size, 1-1/4" x 6-7/8", in anodized aluminum for hollow metal, aluminum or wood frames, with 613 oil rubbed bronze and 628 clear anodized finishes. If the preps vary opening to opening, the Camden CX-ED1689L-4 is a fire rated universal low profile strike supplied with four faceplates, the Camden CX-ED1799L-8 ships with eight, and the Von Duprin 6400 is a Grade 1 modular strike that serves mortise or cylindrical locks.

The ROFU 3403 keeper is sized for latch projection up to 5/8", with a reversible non-handed body. Where a mortise lock is specified by name, the Securitron MUNL Mortise UnLatch is a Grade 1 fire rated mortise strike, the Von Duprin 6210 is a Grade 1 heavy duty mortise lock strike at 24 VDC fail-secure with UL 10C fire rating, and the Hager 2930 covers both cylindrical and mortise locks.

The ROFU 3403 is a frame-mounted strike with a reversible non-handed keeper for a single latch. For a double door application, the Rockwood electric strike is built for double doors with a 3/4" keeper and is Grade 1 and fire rated.
