@Steven posted:Mannyrock and PH1975 thank you for your responses. Ill check EBAY. I have not found anything as far plastic joiners for fastrack. But will try again !!!
There are no plastic joiners. Block Section 6-12060 and/or the shorter 1+3/8" track 6-12073 are used instead. Note that 2 sections are required to fully isolate in either instance.
