Cal-Royal ICCAT04 Grade 1 Communicating Lock - Accepts SFIC Core

The Cal-Royal ICCAT04 is a Grade 1 communicating lock from the Genesys Series, built with the AT lever and set up to accept a small-format interchangeable core (SFIC, core not included). A communicating lock is an uncommon and often misunderstood function, so it's worth being clear up front about what makes it different: this is a dual-cylinder lockset where a key in either lever locks or unlocks its own level independently. That specific behavior is what the ANSI F80 communicating function means, and it's the reason this lock exists for a particular kind of opening.

What a communicating lock actually does

Most locks control one side of the door. A communicating lock controls each side separately. There's a keyed cylinder in both the inside and outside lever, and turning the key in either one locks or unlocks that lever on its own, without affecting the other. The latchbolt is deadlocking and operated by the lever from either side when unlocked.

This matters for openings where two parties need independent control of the same door, the classic example being connecting doors between adjoining hotel or motel rooms, where each room's occupant can lock their own side. It also fits suites, adjoining offices, healthcare rooms, and any communicating doorway where you want either side to be able to secure itself independently. If you've been searching for a communication lock for a connecting door and weren't sure how the function works, this independent dual-key control is exactly it. Just confirm the F80 communicating function is what your opening needs, because it behaves differently from a standard entry or storeroom lock.

Why choose the Cal-Royal ICCAT04

Cal-Royal builds Grade 1 commercial hardware at a price that works for projects watching the budget, and the Genesys Series gives you genuine ANSI Grade 1 performance across a full range of functions. Two features make the ICCAT04 a smart pick for a communicating opening. The SFIC capability means it drops into an existing small-format interchangeable core key system (BEST, FALCON, ARROW), so you manage it on the same keying platform as the rest of your building and rekey it in seconds by swapping the core. The CLUTCH free-turning lever protects the handle from being snapped when someone forces a locked lever, which is exactly the kind of abuse a communicating door between rentals or rooms tends to see.

One thing to confirm before ordering: the core is not included, so you'll need a compatible SFIC core, and the communicating F80 function is specific, so make sure independent dual-key control is what your connecting door actually calls for rather than a standard entry or privacy function.
