Was watching the show last night and in the "what is it" segment the guys presented a tool usefull to hold large tarps. It consisted in two yellow interlocking tubes that could lock over a large tarp to hold it.
The show was presented last night (January 29th in Montréal,Qc so broadcast from vermont somewhere) on PBS but I can't find the show number anywere.
Info would be usefull.
Thanks in advance.
