High-Impact PVC Ramps Help You Create Custom Fiber Cable Routing Schemes The SmartRack SRFC5RAMP connects to straight channel sections or other fittings in your fiber routing system to raise or lower it to a different level. Two of Tripp Lite’s SRFC5CPL5 couplers (sold separately) are required to complete your installation. Made from durable, lightweight PVC material, these ramps connect to each other using the included hardware to help keep your fiber optic cable bundles neat and organized. Screws tighten by hand with no tools required to complete a professional, finished look in your data center, network closet or industrial space.
