Product review (4 stars): Once you get part trimmed, it is a breeze!
Our installation required a bit of DIY work..the soft part of gasket fit well..the firm part (heavy plastic) was 1/4 inch too long for our unit.  Used a hack saw blade to trim the bottom..you will need to dry fit soft part first to make sure latch areas line up..then decide if you need a bit of a trim before proceeding.  Written instructions would have been nice.  You will have to Google youtube to find out how to install.
