A guy on my crew swears coax staples are fine, I say they crush the dielectric, settle it for me
Last Thursday in Mesa I pulled a line off a wall that another guy stapled down 5 months back, and the dielectric was flat as a pancake right at the staple, signal was garbage at the box. He says staples save time and the fittings still pass, I say a crushed line costs you a callback you don't get paid for. We argued about it for 20 minutes in the truck while the homeowner stared at us. So who's right here, staples or screw on clips, and does it change if the run is inside a wall? Genuinely want to hear what you all do.
Mesa in July heat, that staple was probably driven through softened jacket and you got a bad pinch, but one crushed line does not prove staples are wrong every time. A T25 staple shot with a light trigger pull and a proper cable stapler leaves the jacket round most of the time, and I have pulled plenty of stapled runs from 2019 that still sweep clean on a certifier. The real problem is the tool and the hand, not the staple itself, and guys who blame the staple are usually the same ones leaning on the gun. Screw clips take triple the time on a long home run and half of them strip out in drywall anyway, so now you have a clip spinning on a screw and a line flopping around. Inside a wall changes nothing for me, a staple does not care if it is behind drywall or in a crawl, the crush point is the crush point. What actually kills you is no service loop and stapling tight around a bend, that is where the loss shows up at the box.
