After ordering and receiving 4 portlights from Sailnet, I finally had the time to install them. The 8X18 and the 7X15's had 1 7/8" spigot lengths. Today I removed one 5X12" and when I removed the replacement from it's box, it had a 2 3/4" spigot length! I thought I had ordered a 1 7/8" spigot. I have been looking and can not find a 5X12 with a spigot shorter than 2 3/4". Any suggestions? Has anyone ever cut a spigot to reduce the length?
