Vista Pro’s Infinity Knuckle provides seamless, weatherproof aiming control for steplights and accent fixtures. Its patented spherical grommet design allows infinite adjustment in multiple axes while protecting conductors and maintaining fixture seals. Fixtures can be aimed precisely and locked in place, delivering both flexibility and long-term reliability for architectural lighting applications.
Precision Aiming. Built-In Protection.
Infinity Knuckle Technology
A precision-engineered spherical grommet system delivers secure positioning and reliable sealing in one integrated design. As the central pivot screw is tightened, the grommet compresses to lock the knuckle in place while sealing around internal wiring and components.
The articulating assembly allows smooth adjustment without pinching or stressing conductors, ensuring long-term performance and durability. Integrated sealing features protect against moisture and environmental exposure at all critical entry points.
A durable stainless steel mount stem enables easy installation across a range of applications. Its built-in rotation stop prevents wire twisting, while the pre-install design allows mounting hardware to be secured before fixture placement.
The result is a streamlined aiming solution that combines flexibility, protection, and installation efficiency.
Key Features
Infinite Adjustment
Aim the fixture anywhere without step limitations.
Dual-Axis Rotation
Two set screws allow rotation along separate axes for complete light control.
Weatherproof Sealing
Spherical grommet prevents water ingress and seals rotating screws.
Lockable Positioning
Secure the fixture in the desired orientation.
Patented Design
Single ball provides all three seals while enabling infinite aiming.
How It Works
Loosen the first set screw to rotate along one axis, then the second screw for rotation along the other axis.
Encapsulates the knuckle halves, screws, and conductors to maintain weatherproofing while allowing infinite movement.
Tighten screws to secure the fixture at the desired aim.
