For projects requiring a security door lock set, choose from our deadlatch, deadlock, deadbolt, cylinder lock, or entry door locks and deadbolts. Update old entries with enhanced security via flush bolt door hardware, an indicator lock, electric strikes, and all the necessary accessories, including door catches and latches. Choose a thumb turn lock or mortise lock to safely secure important items or documents. Ensure safety for all with a door paddle lock paired with our emergency exit door alarm or door chime.
