Quote: Can I ask something? If you eliminate where the ends are folded and interlocked together, and just overlap and glue them together, wouldn't that make the process easer and a little cheaper? Thats how the Fram filters were made, and it has a cleaner look.
Everyone is entitled to an opinion, and there are alot of different views on that subject. The current method by most mfg. for joining the outer screen ends is overlap and spot welded (not glued) it never has been glued whether perforated or expanded outer. The lock seam method we use for NMS Performance filters is a much more positive (and in most views) a cleaner looking seam. The lockseam was the method used for Chrysler Corp. OEM units before it was changed for cost reduction reasons, so we choose to use the OEM method.
