Before trying to measure the distance between the holes on your main drain cover, please go to FAQ page under “Q: How do I determine which clip will fit my main drain cover?” to see if your drain cover is pictured with the associated clip to fit.
If your drain cover is not pictured, you can use your pool basket as a measuring device. Put two strips of electricians tape on the “scoop” edge of your pool basket, separated by 6-3/8” inches as pictured below. From the side of the pool, place the basket “scoop” edge over your pool drain to measure the distance between the holes on the pool drain cover.
-
- Less than 6-3/8” inches, D1 SMALL Clip
-
- 6-3/8” or slightly more, D1 LARGE Clip
-
- Well over 6-3/8”, D1 EXRENDED Clip
If the distance between the holes on your drain is from 6-0″ to 6-3/8″ apart, the D1 SMALL clip will fit.
If the distance between the holes on your drain is from 6-3/8″ to 6-3/5″ apart, the D1 LARGE clip will fit.
If the distance between the holes appears to be a lot greater than 6-3/5″ apart, you have a 10″ drain and you need the D1 EXTENDED CLIP PACKAGE.
