ROFU 1106 Weatherproof Electric Strike, Fail Secure

That's what the 1106 is built for. It's a weatherproof fail-secure strike intended for gate locks, with a one-piece cast zinc alloy body rather than an assembled housing, so there are no seams for water to work into. It's tested past 250,000 cycles and holds 1000 lb (470 kg) static strength. For an exterior gate or a perimeter door that sees weather, this is the right class of strike; an indoor-only economy strike will corrode out on that opening.

It stays locked. Fail-secure means the keeper holds the latch when power drops, so the opening remains secured and you get in with the key or by the mechanical lever on the inside. That's usually what you want on a perimeter gate or exterior door. If your opening is an egress route that has to release on power loss, you need a fail-safe strike instead, not the 1106.

No handing to specify. The 1106 is non-handed and fully reversible, so the same strike works on a left or right hand opening. For a property manager standardizing across a site, that means one part number covers every gate regardless of swing, and stocking a spare doesn't mean stocking two.

Two voltage builds are offered: 8-16 VAC, and 12/24 VAC/VDC. Pick by how the strike is driven. On DC the strike runs continuous duty, so if your access control board holds the strike energized (card reader unlock windows, timed schedules, REX held open), you want the 12/24 VAC/VDC version wired on DC. AC power is for intermittent use only, not exceeding 10 seconds per activation, which suits a doorbell-style momentary buzz-in off an existing AC transformer. Running an AC strike on a long unlock cycle will cook it.

Either one. The 1106 strike body suits both cylindrical and mortise locksets, so you can keep whatever lock is in the gate or door now and just swap the strike side. It mounts in hollow metal and wood frames.

No. The ROFU 1106 is built for hollow metal and wood frame doors with cylindrical and mortise locksets. Aluminum jambs are a different prep: the Adams Rite 7100 series and 7160 series are electric strikes made for aluminum jambs with a 1-1/4 inch by 4-7/8 inch faceplate. For a hollow metal or wood jamb using that same 1-1/4 inch by 4-7/8 inch faceplate, Adams Rite builds the 7170. Glass front installers working narrow stile aluminum should be looking at the 7100 or 7160 rather than the 1106.

The ROFU 1106 is a weatherproof strike for gate locks and is not offered as a fire rated device. For a fire rated opening, the Von Duprin 6400 32D is a Grade 1 modular strike for mortise or cylindrical locks with a 3-hour UL 10C rating in fail-secure, and the Von Duprin 4211 32D is a Grade 1 fire rated strike for cylindrical locks with 12/24 VDC field-selectable voltage. The Hager 2930 is a fire rated Grade 1 strike for cylindrical and mortise locks with 12/24VDC dual voltage. All three carry a fire rating the 1106 does not, which is the deciding fact on a rated assembly.

For a spec that names ANSI Grade 1, order from the peers that carry the grade. The Alarm Controls AES-100 is a Grade 1 heavy duty electric strike. The Von Duprin 6400 32D is Grade 1 modular for mortise or cylindrical locks in fail-secure, the Von Duprin 6210 is Grade 1 heavy duty for mortise locks at 24 VDC fail-secure with UL 10C fire rating, and the Von Duprin 4211 32D is Grade 1 for cylindrical locks. The Securitron MUNL mortise UnLatch strike is Grade 1 and fire rated. The ROFU 1106 is a commercial weatherproof gate strike whose published strength figure is 1000 LB static and 250,000+ cycles.

No. The ROFU 1106 is suited to cylindrical and mortise locksets. A rim device with a Pullman latch needs a rim mount strike: the SDC 30-4 series is a 3/4 inch Pullman latchbolt rim mount electric strike in stainless steel construction. For surface vertical rod devices, the HES Folger Adam 310-4-2 is a complete Grade 1 electric strike pac. The Hager 2945 is a fire rated rim exit strike with field selectable fail safe or fail secure. Confirm the device type at the door before ordering the 1106.

The closest peer for a gate is the Camden CX-ED1959 Series, an outdoor rated electric gate strike. The Trine EN4301 is another indoor/outdoor option, fire rated, 12VDC, with field selectable fail safe or fail secure operation and a 4-7/8 x 1-1/4 inch faceplate handling up to a 7/8 inch throw. The 1106 differs from that Trine in one respect that matters on the order form: it is fail secure only, not field selectable, so if you need the option to flip the mode later, that decision is made when you buy.

No. The 1106 is fail secure, fixed. For field reversible operation, Hager makes three: the 2925 with a 5/8 inch latch, the 2928, and the 2930, all field reversible fail safe/fail secure. Von Duprin's 4211 is field-selectable on voltage at 12/24 VDC and Grade 1. Decide the mode before ordering the ROFU, because you can't change it on the job.

It's a commercial strike, and the numbers back that: 1000 lb (470 kg) static strength against a pull on the door, and testing past 250,000 cycles. The one-piece cast zinc alloy body carries that load as a single casting. For an apartment gate or a service entrance cycling a few hundred times a day, that's the duty range it's built in.

Latch monitoring is a separate feature set. The Dortronics 3300 series is an electric strike with a latch bolt sensing switch at 12/24VDC and a strike plate for ANSI prep of 4-7/8 inch by 1-1/4 inch. The Hager 2945 is a fire rated rim exit strike with field selectable fail safe or fail secure and a latchbolt monitor, and the Camden CX-ED1799L-8 is a fire rated dual monitor Grade 1 strike shipping with 8 faceplates. The ROFU 1106 is a fail-secure weatherproof gate strike; it is specified on strength and weather exposure rather than on monitoring outputs.

The ROFU 1106 is ordered in an 8-16 VAC build and a 12/24 VAC/VDC build, and it can be powered by VDC for continuous duty or VAC for intermittent use not exceeding 10 seconds. On voltage alone, the Trine 004 is 8-16VAC fail secure with a 6-1/4 inch by 1-3/8 inch faceplate and up to 5/8 inch throw. The Trine 2001 runs 16-24VAC/DC fail secure with a 5-7/8 inch by 1-1/4 inch faceplate. On the DC side, the SDC 15 series operates at 12/24 VDC with a 5/8 inch latchbolt. Match the strike to the transformer already on the job, then check the frame and the fire requirement before ordering.

The ROFU 1106 is a one-piece cast zinc alloy body, non handed and fully reversible, which removes handing from the retrofit but not the frame prep. When cutting the frame is off the table, the Locknetics NC450 is a no cut electric strike. When the frame is already prepped to the ANSI 4-7/8 inch by 1-1/4 inch cutout, the Dortronics 3300 ships with a strike plate for that prep and the Adams Rite 7170 carries the same 1-1/4 inch by 4-7/8 inch faceplate for hollow metal and wood jambs. Strikes that ship with multiple faceplates also cover odd frames: the Camden CX-ED1689L-4 includes 4 faceplates and the CX-ED1799L-8 includes 8.

Two traps. The HES 1500 and HES 1600 items are electric strike accessories rather than a complete strike, so they will not stand in for the 1106 at an opening that needs a working device. The HES Folger Adam 310-1(X) is an electric strike body for 1/2 inch, 5/8 inch or 3/4 inch throw latchbolts - a body, again, not the full assembly. The ROFU 1106 is a complete one-piece cast zinc alloy fail-secure strike for cylindrical and mortise locksets. Also check duty: the Rockwood double door strike with a 3/4 keeper is a Grade 1 fire rated 310-1 series device for a pair of doors, a different opening than a single gate.

The SDC value strikes are sorted by latchbolt: the SDC 15 series takes a 5/8 inch latchbolt with 12/24 VDC operation, and the SDC 25 series is built for 1/2 inch latchbolt compatibility. The SDC 45F is the fire-rated one, with 5/8 inch latchbolt compatibility and a radius corner faceplate. The ROFU 1106 is fail-secure and non handed, made for cylindrical and mortise locksets in hollow metal and wood frames, weatherproof and rated to 1000 LB static strength. Measure the latchbolt throw first: that is what sorts the SDC line, while frame type and exterior exposure are what sort the 1106 in.

One model will not. The ROFU 1106 covers the exterior gate side: weatherproof, fail-secure, cast zinc alloy, 1000 LB static strength, non handed and reversible, for cylindrical and mortise locks in hollow metal and wood frames. Fire rated openings need a rated device such as the Camden CX-ED1410 and CX-ED1420 universal Grade 1 ANSI fire-rated strikes or the Von Duprin 6400 32D with its 3-hour UL 10C fail-secure rating. Aluminum storefront needs an aluminum jamb strike such as the Adams Rite 7160. A practical standard is three models by opening type rather than one across the site.

Two: 628 clear anodized and 606 satin brass. Both are offered in either voltage build, so finish and voltage are independent choices on the order. Clear anodized is the one that matches aluminum gate frames and most storefront hardware on a site; satin brass suits older brass trim you're trying not to break up.

The ROFU 1106 is built in 606 satin brass and 628 clear anodized, both paired with either the 8-16 VAC or the 12/24 VAC/VDC build. Among the comparable strikes, the Locknetics MS100, MDS100, CS450 and NC450 are all US32D, the Von Duprin 4211 and 6400 are 32D, and the Von Duprin 6400 is described as satin stainless steel. For a property manager standardizing gate and door hardware across a site, 606 or 628 on the 1106 will not match a US32D satin stainless run, so pick the finish family before spreading the order across brands.
