Panic & Exit Hardware: what shapes the quote
Locksmith · Richmond Hill, Ontario
Dogging holds the device's latch retracted so the door works as a simple push-pull for a period, useful during business hours on a busy entrance. It is not available on fire-rated openings, because a fire door must keep an active latch at all times; on those doors, electric latch retraction achieves a similar push-pull convenience without ever leaving the latch mechanically held back.
Fire-rated versus non-rated opening
A fire-rated door needs hardware specifically listed for that assembly and installed to keep the rating intact, which is more involved than fitting a standard device to a non-rated door.
Outside trim selected
A plain pull is the simplest outside trim. A lever with a key cylinder, or a trim matched to other hardware finishes in the building, involves more parts and more fitting time.
Access-control integration
Where the door ties into an existing access-control panel, coordinating the exit hardware's signals with that system takes planning with whoever maintains it, which the quote accounts for separately from the device itself.
