External Overflow Box 1.5" Bulkhead Gasket

Product description should highlight the issue with rimmed tanks, and normal retailers should stock the product, or the extra should be included. Took a silly amount of extra time to install ordering pieces that should have been included, broke a tank trying to over tighten. Not at all happy with the water level. Spent 100+ bucks on something that out of the box doesn't work, and even with extra parts is disappointing. Will not recommend.

Love it, and it's been 15 years since I drilled a tank, not to mention twice. My 80 is 20 years old this year and it drilled perfectly. I run both outer overflow bulkheads into my sump, and it does a fantastic job.

Just what I needed for the framed tank.
