I am making and selling Toe-Tappers like you see in the picture above. The only difference is that I'm making them with a 1/2" thick HDPE base (that's 3/4" in the picture). The metal hardware is all stainless steel.
If you have purchased the PDF Specifications and decide to buy one of these assembled Toe-Tappers, I will refund the $4 you paid for the specifications.
I am guaranteeing that the tap adapter fitting will work for you for one year from the purchase date. If you have a problem with it in the first year, I'll replace it at no cost. After one year, if the adapter fitting fails to work, you can purchase a new one from Gardener's Supply.
Price: $45.75 (plus $6 for shipping)
Availability: In stock and ready to ship.
