In Media Technology at [our] university we use a lot [of] the Nelco cable mesh in our classrooms either it be on our cables for laptop uses or the cabling tethering the lectern to the wall. We also use a lot of the various Velcro to help manage cabling and holding down our equipment in our lecterns along with the cable ties. We have been using these products for over 10 years and still going strong. And lets not forget the terrific service they have provided over the years either it being a simple request to a complex one they have always been on top of it.
Nelco's Weather Resistant Nylon 12 Cable Ties are rated for outdoor use for 12-15 years. These are ideal cable ties to use on solar applications due to their weather resistant properties.
