Maybe you don’t always have to cut PVC and re-connect it with foul-smelling glue to install it. In some applications, maybe you can just bend it. There are heaters for bending PVC, which at the best smell really bad or at the worst emit some nasty chemicals, but Rack-A-Tiers’ Pipe Viper allows you to bend PVC cold.
The Pipe Viper is a long spring that’s slightly smaller than the inner diameter of the corresponding size Schedule 40 PVC pipe. You slip it into a section of PVC while you’re bending it to maintain the inner diameter of the pipe. Of course, you still need to watch the temperature: The pipe should be 50°F or warmer, or else you could have problems.
CableOrganizer.com sells three models of the Pipe Viper: a 1/2″ diameter by 36″ long spring costing $26, a 3/4″ diameter by 28″ long spring at $28, and 1″ diameter by 36″ long spring at $35. Rack-A-Tiers also makes bending springs in 1-1/4″, 1-1/2″, 2″, 2-1/2″, 3″, 3-1/2″, and 4″ diameters.
