I don't think all local stores have straight through connectors that will work with this cable. Save yourself tons of time and frustration by buying everything together online. This is because the outer diameter of the insulation of individual CAT6a conductors is approximately 1.10mm. The overall cable diameter is approx. 7.2 mm. Make sure any endings you choose work. Example: An ideal CAT6 RJ-45 loop-through does not work under any circumstances.
