Anybody here has any experience with punchdown tools for keystone jack termination? I have this tool http://www.amazon.com/Punch-Down-Impact-Blade-Cutter-HT-324B/dp/B001TPIX54 with the 110 blade using those keystone connectors from Belden http://www.mayflex.com/products/cop...6-unscreened-rj45-keystone-jack---mdvo-style/ Pretty simple concept to wire but my issue is no matter how hard I push on the tool the wires don't stay in place They kind of go inside the "clamp" but just a little bit of pull the the wire(s) comes off. Bad technique or wrong tool?
