Fits 3 3/4” pipe with some slight modification.
If you’re looking for covers to fit 3 3/4” corrugated drain pipe these will work. Just note that when fitting into the male end of the pipe you may have to heat and stretch the pipe a few mm to insert this drain cover. But it will fit!

Love it
What an upgrade from those nasty metal yard drain covers! So sturdy, easy to install, comes in several colors, is not expensive and just stick in in the pipe. Tight fit so no chance of nature causing it to come out! Highly recommend this item!
