Small note of caution if you buy the rapid tomato clips and are trying to match the diameters to the clip you buy.If you use the small barbs(as hold device instaed of slip)try not to use the larger dia.as it will damage the barb and or the malleable poly hinge.I myself use the Greenlee electricians(stranded poly,can split to use with any clip).The natural twine and sisals ,stretch,and worse yet harbor your fungae,molds,mildews and who knows what else.If you want some neat,made for purpose check these guys out.
