3M Company 111H-SQ-48 Indoor Mounting Squares 48 Count

Product Description

The 3M COMPANY 111H-SQ-48 is a pack of 48 double-coated foam mounting squares designed for indoor adhesive mounting applications. Each square uses a foam core with adhesive on both sides, allowing it to conform to a variety of surfaces while creating a secure bond. These are commonly used to mount lightweight fixtures, panels, signage, or components in interior environments. Weighing just 0.36 pounds per package, they are easy to store and dispense on the job. Trade professionals use them for quick, tool-free mounting tasks where mechanical fasteners are not practical.

These indoor mounting squares are suited for interior applications in residential and light commercial settings. Common use cases include mounting nameplates, small panels, wire management clips, and similar lightweight components to painted drywall, wood, metal, and other smooth or semi-smooth interior surfaces. They are not rated for outdoor or high-moisture environments. Installers working in electrical, HVAC, or general construction trades will find them useful for securing labels, covers, and light accessories during rough-in and finish work.

Installation Notes

Surface preparation is critical for adhesive performance — clean the mounting surface of dust, oil, and debris before applying the squares. Press firmly and allow adequate dwell time for the adhesive to bond fully before loading the mounted item. These squares are intended for lightweight applications only; do not exceed the adhesive load rating for the surface type. No tools or electrical shutoff is required for installation.
