Product review (5 stars): Trick to install at bend on LG dishwasher
Fits nicely on my LG dishwasher, though turns out the leak wasn't caused by the old gasket but rather by the dishwasher not sitting perfectly straight on the ground.  My old gasket was really worn, though, and bits were coming off into our dishes.  Having a new one is nice.  A little pricey for a piece of rubber, if you ask me.

The corners were hard to push in because the bend of the dishwasher channel makes the opening smaller.  What you have to do is pull on the gasket to make it ever-so-slightly thinner and simultaneously push it in.  It takes a bit of pushing but you'll eventually get there.
