The Light Source Quad Coupler 1.5 Swivel, Black Anodized is a versatile rigging accessory designed to provide a secure, adjustable connection between standard pipe or tubing and structural elements in lighting, staging, and AV installations. It’s built by joining two standard Quad Coupler 1.5 units so that their flat sides face each other, enabling the assembled clamp to rotate around the pipe or tube axis. This swivel action simplifies alignment of attached fixtures or secondary structures, helping rigging crews position lighting, scenic elements, or support rails more efficiently during setup and changes.

Machined from durable aluminum and finished in a corrosion‑resistant black anodized coating, this coupler is sized to fit 1.25 in–1.50 in outside diameter tubing as well as 1″ nominal pipe (approx. 1.315 in OD) — covering the most common junior‑sized rigging members found in entertainment and event production environments. The swivel design further enhances flexibility by allowing the clamp to rotate freely before tightening, reducing the need for pre‑aligned hardware and minimizing setup time.

Equipped with reliable fastening hardware that includes a 3/8″‑16 × 1.25″ socket head cap screw and a two‑way nylon locking nut, this coupler delivers dependable clamping force that resists loosening under vibration or load movement. With a balanced combination of strength, simplicity, and pivot capability, the Quad Coupler 1.5 Swivel is a practical choice for riggers looking to adapt pipe and tube connections where angle adjustment and secure clamping are both needed.
