The Wood Insert Sleeve is used to cover the hole wherever cable exits a wood or vinyl post on a level run, creating a clean look. These sleeves are necessary in some applications where the cable leaves a post at an angle (i.e. turning multiple post corners, etc.). With the beauty of 316 stainless steel, the Wood Insert Sleeve brings a look of elegance to any Viewrail cable railing system. The Wood Insert Sleeve can be found in the Wood Level Tension Kit.
