A Non-Aggressive Design for an Anti-Climbing Barrier
"The rotating plastic cups are too large in diameter for even the biggest of human hands to grasp making climbing virtually impossible." I can't be the only one to think of throwing a length of rope, a belt, or even a jacket around the roller to make a nice handhold for pulling up, rolling over the wall and lowering myself down the other side. The rollers would also make great pulleys for hoisting people up the wall. So I guess the Roller Barrier is intended for protection only against unprepared or unimaginative wall climbers.
