  • With a high performance cylindrical chassis
  • Smooth operation
  • Easy installation
  • Freewheeling function

FEATURES

Exceptionally smooth operation

To ensure exceptionally smooth operation, the C800 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

DORMA C800 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 C800 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.
