The Iver Osaka Door Lever on Rectangular Backplate — Entrance Set (Key/Key) — brings Japanese-inspired simplicity to a clean rectangular long-plate, configured for keyed locking from both sides of the door. The Key/Key configuration uses a euro cylinder that requires a key to lock and unlock from both the inside and outside. Includes a Euro Mortice Lock (CTC 85mm, 60mm backset) and 5-pin euro cylinder. Suited to commercial applications or shared spaces where controlled access from both sides is required. Crafted from solid brass and fire rated to 2 hours to meet Australian Standard AS1530.4:2014.
