Re: Whirlwind cable ramps
There are a few different kinds of connectors, I believe they are "T" and "dogbone"
You can get cable ramp for as low as $90 on places like discountramps.com, but they have several faults. They are made out of solid rubber which makes them quite heavy, which can be a pain to carry them around and they add up weight in the truck fast, especially when you have a lot of them. The other problem with the cheap ramps is the connectors can sheer off when you pull them apart because they are fairly thin rubber. They would be good in a theatre or some place they don't need to travel.
The bumblebee products are nice, they are some sort of plastic and medium weight, but they seem to have a lot of sharp edges that should be trimmed down or else it kind of cuts into your hands and is uncomfortable to carry. They're solid ramps though.
The standard, which is what I went with are the Guard Dog by Checkers industrial products. They were painful to buy at about $190 each (which is why I only own two :-0 ), however the quality is exceptional and they are a very reasonable weight. I abuse the hell out of mine and they are holding up just fine. I was also able to order mine in all black which is great for corporate and theater work. I did add a thin stripe of fluorescent spike tape for safety in dark areas.
