1RU Lacing Bar Cable Management. Manage your cables neatly without compromising on space with this 1RU lacing bar designed from premium steel that will only occupy one-third of a rack unit. Help reduce those sharp bends that can create kinks and possibly damage the integrity of the cables causing signal bleeds. Installing this in your rack will provide you with ample tie points, this will help you reduce the strain on the expensive equipment. By routing the cable out and away from the equipment you also allow for better airflow for passive cooling.
