Considering the relative thickness of the CAT6 cable (and lack of desire to squeeze/impact the signal) this stapler is a dream. It's very strong, easy to load, requires little force to assemble and has great cable notch/routing (after spending a full day plugging ethernet into our attic, securing the cable with a clamp would have been an issue) . Nightmare). Insulated struts add significant height, so be aware that the struts will not line up perfectly with the cable itself.
