Slide seal question on 2014 3170
Just a question and observation.
The outside bedroom slide seals run in a seal track that is secured to the wall with the standard #2 sq hd screw.
The outside couch slide seals run in a seal track that is secured to the wall with twisted nails.
One nail fell out, seal slide down. I pulled seal off track and saw the nails. Installed the Seal in the track, put a screw the bottom.
Question, why? Productivity would suffer and incur added fastener cost, by using two different fasteners, which would require two different tools on the line.
If any more nail fall out, I will replace with screws and washers.
