Fits great and works well
Great pop in hole plug. Stays in place well. If you want to make it more secure you can bend and flatten the inside fingers of the knockout seal.

The quality was very poor, too poor to use for my purpose. I obtained a much better quality product from another source.

Does the trick, but don't force it
The prongs on these sometimes do not line up quite right and prevent the seal from installing flush. If this happens don't force it, instead take it off and slightly bend the prongs with a needlenose and try again.
