Product Overview
Dormakaba C170D Grade 1 Heavy Duty Cylindrical Lock, Classroom Function, Conventional Cylinder, Non-Handed
The C100 Series Grade 1 heavy-duty cylindrical locksets provide exceptional security, enhanced aesthetics, and rugged dependability.
ANSI F84 Classroom Function: Deadlocking latch bolt operated by trim from either side, except when outside trim locked by key from outside. When outside trim locked, latch bolt is operated by key in outside trim. When outside trim locked, latch bolt operated by inside trim.
Exceptionally smooth operation: To ensure exceptionally smooth operation, the C100 Series locks with lever trim incorporate a cast stainless steel retractor combined with roller bearings. This design provides both extremely high strength and an extended service life for the lock mechanism.
Easy installation: C100 Series locksets are easy to install in both wood and hollow metal doors with ANSI/BHMA Standard A156.115 preparations for cylindrical locks.
Freewheeling function: All C100 Series operating lever trim features a specially designed freewheeling function to protect the lock from damage caused by excessive torque applied to the lever handles. When locked, the outside lever handle will move freely through a 60° arc without operating the latch bolt. This free movement minimizes the opportunity for damage to the lock mechanism.
