It was disturbed with my hacksaw for sure. The gap was where my saw got caught. The amount of force I put on the wire backed media would have crushed any non backed.How much was the media disturbed before that 1st photo was taken? There is a big gap on the right side. Also, hard to say what every filter model in the Endurance line has for a gap between the center tube and media cartridge without inspecting may models. It could vary between models for some reason. Based on the manufacturing QA is these days, it might even vary between filters of the same model depending on manufacturing variances.
