Home Depot has their "Homer" buckets at the new reduced price of $2.98. Unfortunately the white translucent buckets with the graduated marks are still $6.50. However the real deal is Tractor Supply (TSC). White translucent (no marks) buckets 2 for $5.
They do fit, they're just loose. They still sit at the bottom of the bucket like they're supposed to.
Thats weird, the ones that I have, the grit guard is about 1/4" away from touching the bottom the bucket. Mine sits really tight if I squash it in there.
Grit guards fffttt! I drill holes in one bucket and nestle in a second one. Egg crates are a good idea for my second bucket....
