For Outdoor Patios; We recommend using 'aircraft wire' to use as support cable for a professional look and if you choose not to use a support wire then you can mount the string at various pivot points depending on your application. For rooflines; Mount along the roofline in accordance with our all in all clips (ASIN B004TNDB2I) to mount under shingles or on gutters which creates a strait secure line along your home.Your satisfaction is our #1 Priority and if you have any issue at please contact us and we would be happy to assist!
