This mini-scoping retriever can save you enormous time trying to hunt for that
wire inside the wall. The retriever is approximately 4" long collapsed and
easily can fit inside your shirt pocket with its handy pocket clip. The
retriever extends out of 20" and has a hook at the end that will fit through a
1/4" hole. For the Professional Installer this is one of those tools, "when you
need it, you really need it!"
