ROFU 2435 KIT Electric Strike Kit For Mortise Locks

The ROFU 2435 KIT is built for both. It's designed for mortise and cylindrical locksets, so the same kit covers a mortise lock on an office suite door and a cylindrical lockset on a stair or storage door. The kit ships with five heavy duty stainless faceplates, which is how one strike body covers the different frame preps and latch positions those two lock types present.

No handing to specify. The 2435 strike is reversible for left hand or right hand installation, so one part number covers either swing. That matters if you're stocking spares for a building with doors going both ways, you carry one kit instead of two.

Either. The 2435 is fail safe / fail secure, so you select the mode at installation rather than ordering a different part. Fail safe releases the door when power drops, which is what an egress path or a fire alarm interface usually calls for. Fail secure keeps the door locked with no power, which is what you want on an exterior or tenant entry so a power outage doesn't leave the building open. One kit covers both, so a property manager standardizing across a mixed building doesn't have to split the order.

It operates at both 12 and 24 VDC, so it drops onto whichever supply the access control panel already has. Current draw is 250 mA at 12 VDC and 150 mA at 24 VDC. Use those figures when you size the power supply, if you're running several strikes off one panel, the 24 VDC figure is the lighter load per door and gives you more headroom on a long wire run.

The strike measures 3 5/16 inches (4 5/8 inches) x 1 5/8 inches x 1 13/16 inches. The two figures on the first number reflect the faceplate options, the kit includes five stainless faceplates, so you have some latitude to match an existing frame prep rather than cutting a new one. Take the depth figure seriously on a hollow metal frame: 1 13/16 inches of cavity has to be clear behind the prep, and on a frame with a heavy anchor or grout fill that is the thing that stops the job.

Both are electric strike kits with selectable fail safe and fail secure operation. The ROFU 2435 KIT is designed for mortise and cylindrical locksets, is reversible for left hand or right hand installation, runs on 12 and 24 VDC, and ships with five heavy duty stainless faceplates so one kit covers several frame preps. The Adams Rite 7400A is the Ultraline 7400 Series strike body kit with field selectable fail safe/fail secure operation. If the opening needs a fire rated assembly, note that the 7400A carries a fire rating of No, the same as the ROFU 2435 KIT is intended for non-rated openings.

The ROFU 2435 KIT is built for that case. It is designed for mortise and cylindrical locksets and accepts a 1 inch maximum latch throw with a 1/8 inch door gap, with 1000 lbs static strength and a body measuring 3 5/16 inch (4 5/8 inch) x 1 5/8 inch x 1 13/16 inch. The Adams Rite 7400A Ultraline is the other full strike body kit to weigh, and it is also field selectable between fail safe and fail secure.

You install one. The other four are there so the single kit covers the range of frame preps and lock types it's rated for, mortise and cylindrical, left hand and right hand. For a locksmith or integrator working retrofit, that's the point of buying the kit: you go to the door not knowing exactly what prep is behind the existing strike, and you have the plate that matches on the truck. Keep the spares, they're the same stainless as the one you fit.

The closest cross-brand equivalent is the Adams Rite 7400A Series Ultraline electric strike body kit, which like the ROFU has field selectable fail safe/fail secure operation, so you pick the mode on site rather than at the order. The difference to weigh is coverage: the ROFU kit is stated for both mortise and cylindrical locksets and includes five faceplates, so it's the one to reach for when you don't know the prep in advance. The Adams Rite 7400A is not fire rated, which rules it out where a fire door assembly is involved.

Not within the ROFU 2435 kit, its stated limit is a 1 inch latch throw at a 1/8 inch door gap. Where a gap needs shimming, the spacer plates on the market are Trine parts sized to their own strikes: the Trine 4800-SS is a 1/8 inch spacer plate and the 4850-SS is a 1/4 inch spacer plate, both for 4800 Series electric strikes. Those go with a Trine strike body, not with the ROFU. If your frame condition needs a spacer, plan the strike choice around it rather than trying to shim the 2435.

It's the strike, the part that mounts in the frame and releases the latch on command. Your existing mortise or cylindrical lockset stays in the door and keeps working mechanically, including the key and the lever. What changes is that the frame side can release electrically from an access control reader, a buzzer, or a REX. You are not buying a lock here, and the mechanical hardware on the door does not need to change.

No. The Trine 4800-AK is an accessories kit for the Trine 4800 series, meant to supplement a strike already installed from that series. The ROFU 2435 KIT is the strike itself, a heavy duty stainless steel unit for mortise and cylindrical locksets that operates at 12 and 24 VDC and includes five faceplates. Ordering the 4800-AK in place of the 2435 KIT leaves the opening without a strike.

Spacer plates are a Trine 4800 series solution: the Trine 4800-SS is a 1/8 inch spacer plate for 4800 series electric strikes and the Trine 4850-SS is a 1/4 inch spacer plate for the same series. Neither fits the ROFU 2435 KIT. The 2435 KIT instead ships with five heavy duty stainless faceplates and is reversible for left or right hand installation, so frame fit is handled by selecting the correct faceplate from the kit rather than by shimming the body.

The ROFU 2435 KIT is the one to standardize on for that mix. It is designed for both mortise and cylindrical locksets, is reversible for left hand or right hand installation, operates at 12 and 24 VDC with a current draw of 250 mA at 12 VDC and 150 mA at 24 VDC, and includes five faceplates so a single stocked part number covers a range of frame conditions. The Adams Rite 7400A Ultraline is a separate strike body kit family; standardizing on it means stocking the 7400 Series instead.
