The Light Source Mega-Square 2 Inch Swivel Coupler is a versatile and robust connector designed for joining two sections of 2-inch square structural tubing at a variable angle. Featuring a bright silver finish, this coupler is constructed from heavy-duty steel or aluminum and incorporates a pivotal swivel mechanism within its design. Unlike fixed couplers, this unit allows one tube to be positioned at a wide range of angles relative to the other—typically offering 360 degrees of rotation and a significant tilt range—before being locked securely in place. This adjustability is controlled by a central pivot bolt and a separate clamping mechanism that tightens around the tubing, enabling the creation of custom angular joints for complex frameworks.

The coupler consists of two primary parts: a base clamp that secures one square tube, and a swiveling head that clamps the second tube. The swivel head rotates around the central bolt, which also serves as the main tightening point for the angle lock. Once the desired angle is achieved, a large hand knob or a wrench-tightened nut on this bolt is secured, freezing the joint's position. Additionally, each clamping jaw utilizes its own set screws or bolts to firmly grip the 2-inch tube, preventing slippage and rotation within the clamp itself. The silver finish, often a plating or powder coat, provides a reflective, clean look while offering protection against corrosion.

This component is essential for fabricating custom geometric structures, support braces, and adaptive framing where non-standard angles are required. Applications include trade show displays, custom furniture frames, art installations, and temporary support systems where adjustability during the build phase is a major advantage. The Mega-Square Swivel Coupler provides the flexibility to create a multitude of shapes from standard square tubing, combined with the strength to lock those shapes into a rigid and load-bearing configuration. It effectively bridges the gap between the versatility of a movable joint and the stability of a fixed weld, offering unparalleled design flexibility in modular metal construction.
