Alarm Lock SC544 – Frequently Asked Questions

1) What does the Alarm Lock SC544 extended screw fit?
The SC544 is a genuine Alarm Lock extended screw for ETDL series lock assemblies. It is a direct drop-in replacement, so no drilling, tapping, or adaptation is needed on an ETDL lock you already have installed. If the lock you are servicing is not an ETDL, this is not the screw for it.
2) Do I order anything besides the SC544 screw to rebuild an ETDL lock?
The SC544 is sold as the extended screw only, one part number with no options or variations to specify. Any other ETDL components you need (chassis parts, trim, or fasteners of a different length) are separate Alarm Lock part numbers.
3) Is this screw suitable for high-traffic commercial doors or is it a residential part?
It is a commercial-grade component. Alarm Lock classifies the SC544 as commercial door hardware, and it is the part used to service ETDL locks in offices, schools, healthcare, retail, warehouses, government buildings, and multi-tenant properties.
4) Why would an ETDL lock need an extended screw rather than a standard one?
Extended screws are the longer fasteners used where the lock assembly has to reach through additional material or stack-up in the ETDL build. The SC544 is the length Alarm Lock specifies for that position, so swapping in a shorter generic machine screw can leave the assembly loose or fail to engage the threads fully.
