3M Company 859S Clear Removable Mounting Squares

Product Description

The 3M COMPANY 859S is a pack of 35 clear removable mounting squares designed for lightweight, residue-free attachment of objects to walls, surfaces, and displays. Each square measures 11/16 inches by 11/16 inches and holds up to 1 pound per square. The adhesive is pressure-sensitive and removable, leaving no oily residue and requiring no solvents for cleanup. These squares are commonly stocked by facilities maintenance crews, electrical contractors, and HVAC service techs for securing lightweight labels, covers, and signage in mechanical rooms and commercial spaces.

These mounting squares are suited for both residential and light commercial applications where temporary or semi-permanent attachment is needed without surface damage. Typical use cases include mounting instruction cards, wiring diagrams, service labels, and lightweight panels to smooth, clean surfaces such as drywall, metal cabinets, and plastic enclosures. The clear profile keeps them low-visibility on finished surfaces.
