To specify a partition system select the Elegant Series post style you would like to use below and click on the link to open a layout page. To use the layout page you click on the grid segments everywhere you want to put a glass panel. The system will add the appropriate posts automatically. Just below the birds-eye layout area you will see a list of all the post you will need for your layout, and below that you will find a numbered list for the glass panels. Adjust the width of the individual glass panels to match the post-to-post center-line measurements of your layout., but don't exceed the maximum post-to-post center-line width is 48 inches for 1/4" partition glass . If you add an upgrade of a top self you should not exceed a post-to-post width of 42 inches. Individual posts can be purchased on the Elegant Series hardware page. This page assumes a few of the partition specification such as 1 inch air-gap under the glass, standard cap, 1/4" clear glass, and no design on the glass. Some of these options can be adjusted on the layout page and some can't (air-gap). To specify all aspect of the posts and partition system use full EZ-Spec system. Use the Help buttons on the page when first starting.
