About a year ago I bought a threaded set of 2 1/4" inserts for a pet urn from Rick at fromwalnuttoantlers.com. Worked and looked great. I liked them better than using the PVC couplings. Want to buy a couple of more sets but the web site seems incomplete and unresponsive. Has anyone else used these inserts and possibly know if they're still available? Or know of an alternate supplier. Cheers
