F2 Indoor Door Stainless Steel Smart Lock
F2 is a 304 stainless steel indoor-door smart lock for room wooden doors and office doors, with TTLock or optional Tuya, 4 AAA power, 35-55 mm door thickness, and single-latch or optional 4585 mortise choices.
Choose F2 for indoor wooden-door and office-door projects.
F2 fits indoor projects that need 304 stainless steel hardware, 35-55 mm door thickness, TTLock or optional Tuya, 4 AAA power, Type-C emergency power, and a clear latch or 4585 mortise decision before pricing.
Indoor wooden and office doors
F2 suits room wooden doors and office doors when the project needs a stainless steel indoor lock for 35-55 mm doors.
304 stainless steel panel
Use F2 when the sample needs a 250 x 60 mm panel, stainless steel or Athens black finish, and a compact indoor-door appearance.
TTLock or optional Tuya
Choose TTLock for higher credential capacity, or optional Tuya when the project needs Tuya App workflow and 9-language setup.
Latch or 4585 mortise planning
Single-latch 50 mm or 70 mm backset and optional 4585 mortise choices help your installer match the prepared indoor door.
Confirm whether F2 matches the indoor door before choosing TTLock or Tuya.
Check room or office door type, 35-55 mm thickness, latch or 4585 mortise, opening direction, handle clearance, finish, language needs, and App platform before requesting F2 pricing.
Room wooden doors
Choose F2 when room wooden doors match 35-55 mm thickness and can accept the selected latch or optional 4585 mortise.
Office doors
Select F2 when office doors need fingerprint, password, RFID card, App access, and a stainless steel indoor panel.
35-55 mm door thickness
Check the measured thickness before samples because F2 is narrower in fit range than many entrance or apartment models.
Latch or 4585 mortise
Confirm 50 mm or 70 mm single-latch backset, or the optional 4585 mortise size, before choosing the hardware.
Choose the F2 TTLock or optional Tuya indoor-door package.
Compare the two F2 versions before pricing because App workflow, credential capacity, language setup, latch or 4585 mortise choice, and remote-control needs can change the quotation.
