The Heil Sound FL-2 Flange Mount is a surface-mounted desk mount designed to provide a fixed base for compatible mic arm or microphone stand setups. It attaches to a desk, table, or tabletop using three included screws, creating a stable mounting point for supported boom arms such as the PL2T, SB-2, and HB-1. The flange base includes a built-in locking mechanism that allows the boom arm to be tightened and held in a chosen position, supporting controlled placement during use. A brass insert with a 1/2-inch thread serves as an adapter connection for compatible arms or extensions. Its low-profile design integrates into desktop or studio workspaces, offering a structured alternative to clamp-based mounts for applications such as podcasting, radio, music production, or general audio setups.
