This was perfect, it was a signficant savings over the filter available at the big box home store.  It had the zip ties and the little adhesive backed brackets so you can mount the filter against the back of the refrigerator. All that is needed is to push in the inlet and outlet 1/4" OD tubing.

Very easy install.
