TOM'S TECH TIPS
SIGMA60 & 2X6 CARRIERS
Are you familiar with the Geberit actuator plate, the Sigma60? If not, you should be. Geberit offers a lot of stylish and gorgeous actuator plates, but the Sigma60 is one of the sleekest (and one of my favorites) because it mounts flush to the wall. So. Sleek.
There's just one problem. You know how all Geberit actuator plates fit all of their carriers, so the plumber can install the carrier ahead of time and the homeowner can take their time and choose the actuator plate at their leisure? Yeah, that's not necessarily true with the Sigma60. [Sad trombone noise.] I say again: not necessarily true. But no need to worry: here is my Tech Tip to the rescue.
Let's consider two scenarios and how they apply to the statement "Geberit actuator kits fit all carriers, so the plumber can install the carrier ahead of time without concern of which actuator plate will be selected later.":
Scenario 1 – Your client is using a 111.798.00.1 2x4 carrier: The above statement is true**. It will not matter if your client chooses the Sigma60 or any other actuator. (**Sigma80 also requires an electrical connection that needs to be pre-planned, but we'll cover that in a future Tech Tip!)
Scenario 2 – Your client is using a 111.335.00.5 2x6 carrier: The above statement is false. [Even sadder trombone noise.] The contractor will need to know ahead of time if your client wants to use the Sigma60, because the Sigma60 requires a special rough-in that needs to be installed before the wall is closed.
The truly nerdy among you will want to know why the 2x6 requires a rough-in and the 2x4 does not. Are you ready for this? Are you ready? The mudguard of the newish 2x4 carrier (introduced last year) is the same part as the rough-in that is required for the installation of the Sigma60 with the 2x6 carrier. Crazy, right? (I suspect that at some point the mudguard for the 2x6 carrier will adopt this design change as well.)
It's understandable if you're confused. It's a lot easier to understand the actuator installations with some visual aids. It's not required viewing, but if you're interested, check out the installation video of the Sigma60.
The important thing to remember is this: If your client is using a 2x6 carrier, they need to figure out whether or not they're going to use the Sigma60 before the wall is closed, and if the client wants the Sigma60, you must order the special rough-in.
Apply what you learned: What is the part number for this special Sigma60 rough-in? (Hint: See page 6 of the 2017 Geberit Price Book for important information about the 2x6 carrier and compatible actuator plates.)
