Oatey 42239 No-Calk Shower Drain Wrench - A specialty wrench used for installing/removing the locking/caulking nut on compatible no-calk shower drain assemblies where this Oatey tool is specified.
Key Features:
:
Product type: Wrench
Oatey part number: 42239 (also listed as "No-Caulk Shower Drain Wrench - Carded")
UPC (manufacturer listing): 038753422398
Q&A dimensional detail: 3.75" diameter across the pins; spacing between each pin is about 1.5"
Compatibility & Applications:
:
Intended for use where an Oatey no-calk shower drain wrench is required (fit is drain-model specific)
Q&A guidance indicates it is most likely only compatible with Oatey drains; for other brands/models (e.g., Sioux Chief), the drain model number is needed to confirm fit
Must only be used where the manufacturer specifies this exact part number: 42239
Installation & Operation Notes:
:
Use should be performed by a qualified plumber or experienced installer, following the shower drain's installation/service instructions
Oatey no-calk shower drains are described as sealing to pre-formed shower bases with fiber/rubber washers (follow the drain's instructions for sealing and tightening steps)
Confirm tool-to-drain engagement before applying high torque to avoid slipping or damage
Maintenance & Troubleshooting:
:
Common service need: used when a no-calk drain locking/caulking nut must be tightened/loosened (e.g., when addressing a leak and replacing a seal/gasket)
Review feedback indicates that if a drain nut is fused/seized, the tool may slip off or fail under extreme torque; in those cases, the issue may be the drain/nut condition rather than the wrench
If the tool is damaged (bent/broken prongs), replacement is typically required to continue service safely
User Reviews & Q&A Summary:
:
Many reviewers describe it as the "right tool" and "invaluable/mandatory" for tightening or removing no-calk drain nuts - especially when the small tool included with some drains isn't sufficient
Common positives: works as advertised, makes the job easier, and is useful to have on hand for occasional drain service
Common negatives: a few reports of the tool slipping or breaking under heavy force, particularly when the drain nut is unusually stuck or over-tightened
When i installed my Shower! I bought An Oarey Shower Drain!I used the Wrench that came with it To install The drain! After about ten years The pipe slipped Down! I should have put a Strap To hold the Pipe up closer to the Trap and drain!

Asked too much of the thing, and it didn't make it.
I don't blame the wrench completely. The drain I was trying to unscrew had been permanently fused in place, I think, by whomever installed it. Possibly by PVC cement or something stronger. However, my vain struggles illuminated the shortcomings of this tool.
1) The center hex-bump supposedly allows you to apply force with your own wrench or ratchet, but it just doesn't have enough grip if you need to apply major torque. My major problem was that the harder I hauled on it, the more often the wrench slipped off the hex, or the prongs slipped out of the drain. There's no way to apply downward force while also turning it.
2) Not sure what metal it's made of, but it's chrome-plated and not super durable. Bits broke off under my most severe abuse, which involved attaching a long wrench to the hex with JB Weld and whacking the end of the handle with a rubber mallet in an attempt to transfer torque from the tool to the drain. The tool broke before the drain did.
I ended up tossing the mangled remains of this thing in the trash, then cut a hole in the ceiling under where the shower was, and sawed off the drain pipe below the connection.

You really need to buy this wrench.
Replaced the gasket in my Jones Mfg. no-caulk shower drain and this was a mandatory tool for getting the job done. The small screw driver tab that came with the original drain just wasn't enough to tighten down the gasket.

Didn't have to crawl under the house
After gorilla tightening by hand the new shower drain into our fiberglass base, we needed to test for leaks. The bathroom floor was already open up near the toilet and the distant PTrap below the shower was awkwardly visible to a contortionist with a cell phone flashlight. So with video running, we plugged the 2 inch ABS pipe, submerged the drain and watched. Yes, we had a leak, but no tool within our reach. We were extremely thankful Supplyhouse.com had this tool in stock for immediate delivery as none of our local stores carried it. This tool fits perfectly inside the internal slots of the drain and was manufactured with a 1/2 inch drive nut at the center. With our socket and a ratchet wrench we easily sealed the drain another quarter turn. The proof is in the video. Every plumber should have one of these!

Great product
It's what should have been included with the drain.

Fantastic product. Definitely worth the price.
Simple to use. Works much better than the piece of metal supplied with drain that needs to be turned with a screwdriver.

Job Much Easier with Right Tool
Best price online, arrived in 1 day! Tool that came with new drain kept slipping, couldn't get enough torque. Got this drain wrench, used a socket wrench with an extension on it, kept slipping, still not enough torque, drain wouldn't budge. Then I used the trick my father taught me. I slipped a 15-inch long piece of plastic pipe onto the handle of the socket wrench to get more torque (physics!) and tried again. The shower drain unscrewed with hardly any effort!
Q: What is the diameter across the four pins on the bottom of the tool used to
spin out the drain? I have a sioux chief no caulk drain in my shower and I
want to know if this tool will fit?

The diameter across is 3.75". The spacing between each pin is about 1.5". Most likely this would only be compatible with the Oatey tool.
