The magnet snaps directly onto any ferrous (magnetic) metal surface — steel gutters, metal roofline edges, fencing, HVAC housing — with no clips, no pre-drilling, and no clip inventory to keep stocked on the truck. Cut to length, slide on plugs, twist in E17 bulbs, then press the line onto the metal and it holds. Available in three spacing\/length combinations so you can match spool count to run length before you cut a single foot.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- Section 3: Verified specs --\u003e\n\u003ch2\u003eVerified specifications\u003c\/h2\u003e\n\u003cp class=\"clhq-source-note\"\u003eEvery value below is pulled from the printed spool label.
