Insulation Support Wire, 16 in.

Keep your batt and roll insulation tight and secure with these 16-inch insulation supports. Made from 14-gauge spring steel, they flex slightly to wedge between standard joist or stud spacing, preventing sagging or gaps. Precision-mitered tips dig into wood framing for a reliable hold without the need for fasteners, while the slim wire profile minimizes thermal bridging.

Each pack includes 100 supports—ideal for new installations or retrofit projects in attics, crawl spaces, basements and commercial ceilings.
