The Matthews 429041 3-inch Baby Plate Stud is a heavy-duty mounting accessory purpose-built for film, video and stage lighting equipment.

By combining the standardized “baby” stud interface (typically 5/8″) with a 3-inch plate, the unit offers a secure base for mounting lights or accessories directly to flat surfaces or stands. This makes it ideal in production rigs, studios or staging setups where flexibility, reliability and safety are paramount.

For installation teams and rental-house workflows, this plate stud streamlines mounting logistics, ensures compatibility with wide arrays of gear and helps maintain consistent mount points across frequently changing setups.
