Installation Tips: Patio Use; 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. Roofline Use; Use in accordance with our all in one clip (ASIN B004TNDB2I) so your C7 bulb points upward and is securely faceted to your gutter or under the shingle. Always mount stringer first then screw in light bulb last. OVER 25 YEARS: Since 1999, Novelty Lights has been a trusted leader in the holiday lighting industry.
