Any ideas on how to fasten sink to countertop?

Does anyone have any ideas on how to re-fasten our kitchen sink to the countertop? Originally, it was fastened using clamps the slid into channels that look like they were tack-welded to the underside of the sink. Slide them in, turn the lip so it is under the counter, and turn the screw to tighten the lip so it clamps the sink to the counter. As shown here:

The problem is a) the clips are so flimsy that they bend, and so they just don't hold over time while subject to road vibration; and b) the channels have all slowly but surely broke free from the sink. I've glued them back on with JB Weld, and while that bought some time, it too eventually failed. And even while the glue held, the clamps were still lousy. The sink is now sliding all over the place, wearing on the counter top and probably the drain line too.

Any suggestions?

Many thanks!
Dave

I managed to find replacement clamps that worked. The tricky part is the channel. You might be able to find some one to tack weld it back. It might be easier to find a new sink.

Thanks, Larry. Where did you get your magical clamps?

I've started thinking about a new sink....maybe I would get lucky, but I'm thinking it's going to be challenging to find one that fits that hole well and has the drain in the same position. There's not much room under there with the water heater and fresh water tank......

I'm pretty pere I got them from Home Depot. As I recall, they weren't in a logical place.

Dave -

If you are forced into this situation, I believe that the factory is now using the HEPvO device that you see on TV. I'm not yet fully confident in this device, but it is apparently code-approved for residential use in the US and Canada, and would save a lot of hassle under the sink.

Great idea, Bill. I’d be far more willing to use that in an RV before a home, so that very well might be useful. Thanks for the tip.

Do you know if the factory uses that in the tub now? If so, I presume that might make the tub slightly lower, giving us tall folks some desperately needed head room.

My 2020 TM has a conventional P-trap in all locations. When I took the factory tour earlier this summer, I saw some partially-built TMs with the HEP unit on the factory floor. A quick note to [email protected] would get your answer right away - Jacob is great.

By the way, no fair bragging about your height. I never quite reached 6 feet, and now I am in that "shrinking fast" stage of my life.
