Review on Aquarium Return Fitting Kit Bulkhead by Amy Ward

Don't waste your money, get a real lock. I knew there was a chance my set would fail. And this set is a giant L. The cheaply made, volumetric head has been threaded on the side so you never have to use a threaded fitting. In addition, it was not round, but oval. Of course, the lock cable had a threaded end, and the bulkhead had a sliding one on that side. I took the risk of buying cheap foreign goods and all must be accompanied by instructions on how to grab your ankles. I knew there would be no refunds so I took that $15 POS and took the £10 sled.
