My installation gets completed next week. In preparation for that, I upgraded the grommets for the cable that runs from the great outdoors into my home. I thought that the grommets that came with the installation kits were too flimsy. I went to McMater-Carr (mcmaster.com) and found something better. On their site, the item is listed as follows. 9280K52 Split Sealing Grommet, 1/4" ID It is rated for outdoor use and should seal better that the Starliink ones. They are pricey but should perform better in the long run. Respectfully submitted, Gary P
