After reading Adam Levy's (adamlevy.com) recommendation for a strap lock in his lesson section, I have been trying to find said washers here in the great white north. He said they are Danco stock # 61805B. They are about 1 1/4" neoprene washer with a a 1/4" hole. You stretch them over the strap nob and presto instant homegrown strap lock. I love these "putterin" kinds of homemade solutions. There is no such animal in plumbing supplies up here in this neck of the woods. At his point I don't believe they can be found in Canada. I can order them up from the US, but to ship them the company wants about 12$ US which seems silly for such a small coin item. I want to get hold of between 2 to 12 of them. Any suggestions or help from anyone would be appreciated. If you can hook me up with a few of these washers, shoot me a PM. I'd send some coin down to cover your trouble. I'll try and see if any are available in the big city when I next excape the northern counties. Right now I am using some homemade ones that I made out of tire tubing that work quite well..... so I don't know why I am fixated but there ya go. Thanks for any considerations from the washer focused retentive fool.
