5″/12.5cm diameter Pipe Rings with 55cm fixing cable tie strap are deisgned to hold standard flowerpots. The inner dimension of our rings are slightly smaller to stop the flowerpot falling through. A pot will ‘sit’ higher or lower in the Ring depending on the flare shape of the pot. The Ring has a vertical strut that goes against the pipe or downpipe – either soil or rainpipe. The cable tie then wraps around the pipe and is pulled tight. There is no damage to the pipe as the weight is directed straight downwards.
