I use these to cover cables in high foot traffic areas at temporary events.Good fitment. They clamp together easily and sturdily. The ramps also hide their connector bits, which make them look a bit neater than their larger 5 channel counterparts.A single cable ramp needs to be gaffed to the floor to prevent it spinning around: they come out of the mold slightly convex and will spin about a low point in the center. Once you've got more than 3 together they don't move under foot traffic.
