ROFU 21036 – Frequently Asked Questions
1) Can a ROFU mini shear lock be installed without mortising the door and frame?
Yes, using the ROFU 21036 surface mount housing. A shear lock normally goes concealed inside the door and header, which means routing both. The 21036 housing carries the lock on the face of the frame and door instead, so an existing opening can take the lock without cutting it apart. Mounting method is surface.
2) What happens to a ROFU mini shear lock in the 21036 housing when the power goes out?
The door unlocks. This is fail-safe hardware, so the lock releases when power drops, which is what most egress-path installations and fire alarm interfaces require. If your application needs the door to stay locked through a power failure, this is the wrong device family.
3) I have a Securitron Magnalock, will the ROFU 21036 housing work for it?
No. The 21036 is built around the ROFU mini shear lock. For a Securitron M32, M62 or M82 Magnalock the matching part is the Securitron full length housing (FLH). For a DynaLock horizontal lock on a 30 to 48 inch single door, DynaLock's 3500 Series custom length housing is the corresponding item. Housings are brand and model specific, not interchangeable.
4) Does the ROFU 21036 come with the shear lock, or is that ordered separately?
The 21036 is the housing only. It is a mounting housing for the mini shear lock, so the lock body and any power supply or access control feeding it are separate line items on the order.
5) Is the ROFU 21036 surface mount housing suitable for an apartment or office building, or is it residential hardware?
Commercial. The 21036 housing and the mini shear lock it carries are electrically operated commercial access control hardware, not a battery unit, so the opening needs a wired power source at the frame before install day.
6) We are standardizing electromagnetic lock housings across a portfolio. Which brands offer a housing option and how do they differ?
Three families cover the common cases. The ROFU 21036 is a surface mount housing supplied as a pair for the ROFU Mini Shear Lock Series. The DynaLock 3500 Series CLH is a full size custom length housing for a single horizontal lock on a single door, in a left hand reverse 30 inch to 48 inch range. The Securitron M32/62/82 Magnalock Full Length Housing serves the Securitron M32, M62 and M82 magnets. Each is tied to its own lock body, so standardizing on a housing means standardizing on the lock line first.
7) Is the Aiphone KA-DGR housing a substitute for the ROFU 21036?
No. The Aiphone KA-DGR is a stainless steel housing for the KB-DAR video door station, so it encloses an intercom station, not a lock. The ROFU 21036 is a surface mount housing pair for a ROFU shear lock, an electronic fail-safe electromagnetic locking device. They share the word housing and nothing else about the application.
