Hey Jeff, thanks for reaching out. I just went out to our warehouse and measured the P&F Products J-Channel Rail for Enclosed Trailers # PF26FR. The interior dimension of the J-channel I measured at 0.17".
What thickness plexiglass were you planning on using?

Hey Jeff, how did things go using the J-channel rail for your horse trailer windows? Did the 0.17-inch interior dimension work well with your plexiglass? Your update could make it easier for others planning a similar setup.
