The RailEasy Cable Sleeve is designed to protect your wood posts from chafing and incidental damage from cable rubbing around the outside of your mid post cable holes
Designed for use on double posted corners and stairs of 45 degrees or less, to eliminate tensioning hardware on post
It can also be used to accommodate angles up to 90 degrees (corners must be double posted) and stairways coming off a straight run
Must have tensioning hardware on both ends of cable run opposite the corner
