Lowell ISO-LL Electrical Isolation Leg Levelers for Floor Racks

The Lowell ISO-LL is designed for AV integrators and system technicians who need a reliable method of leveling floor-standing equipment racks in installations where surface conditions are imperfect and electrical isolation is a requirement. Uneven concrete, tile, or raised flooring can introduce mechanical stress and grounding issues into a rack system. The ISO-LL addresses both problems simultaneously.

The heavy-duty adjustable construction allows each leveler to compensate for surface irregularities independently, keeping the rack plumb and stable without shimming or rework. The rubber base creates an electrical isolation barrier between the rack chassis and the floor, which is a critical consideration in installations where ground loops or stray currents can introduce noise into sensitive audio or broadcast signal chains. Sold as a set of four, the ISO-LL installs directly to the bottom of compatible floor racks and suits permanent installations in houses of worship, broadcast facilities, control rooms, and equipment closets where long-term rack stability and electrical cleanliness are non-negotiable.
