3. Setup & Installation
The MAD OWL Swivel Coupler is designed for quick and secure installation on various truss and pipe structures. Follow these steps for proper setup:
- Identify Mounting Location: Choose a stable and appropriate location on your truss, cross brace, bar, or pole where the lighting fixture or equipment needs to be mounted. Ensure the pipe diameter is within the coupler's specified range of 40-52mm.
- Open the Clamps: Loosen the wing nuts on both O-clamps to open them sufficiently to fit around the pipe.
- Position the Coupler: Place each O-clamp around the desired pipe. The coupler's dual-head design allows it to connect two pipes or a single pipe with a fixture.
- Secure the Clamps: Tighten the wing nuts on both O-clamps firmly by hand. The anti-slip hook and friction rings are designed to enhance grip. Ensure the clamps are snug and do not move freely.
- Attach Fixture (if applicable): If attaching a lighting fixture, use the appropriate mounting hardware to secure it to the coupler's attachment points.
- Verify Stability: Before applying any load, double-check that all wing nuts are fully tightened and the coupler is stable and secure on the pipe. Gently test the connection to ensure it can bear the intended weight.

4. Operation
The primary function of the MAD OWL Swivel Coupler is to provide a secure and adjustable mounting point for stage lighting and other equipment. Once installed, its 360-degree swivel capability allows for precise positioning.
- Adjusting Swivel Angle: The two O-clamps are connected by a central swivel mechanism. To adjust the angle of the attached equipment, slightly loosen the central bolt that connects the two halves of the coupler. Adjust to the desired angle, then re-tighten the central bolt firmly to lock the position.
- Load Capacity: Ensure that the total weight of the attached equipment does not exceed the coupler's maximum tensile strength of 330.69 pounds (150 kg). Overloading can lead to equipment failure and safety hazards.
- Applications: This coupler is suitable for various applications including stage lighting trusses, Rayya frameworks, and round tube scaffolding, offering versatility in setup.

5. Maintenance
Proper maintenance ensures the longevity and safe operation of your MAD OWL Swivel Coupler.
- Regular Inspection: Periodically inspect the coupler for any signs of wear, damage, cracks, or deformation. Check the integrity of the wing nuts, bolts, and the swivel mechanism.
- Cleaning: Clean the coupler with a soft, dry cloth. For stubborn dirt, a damp cloth with mild soap can be used, followed by thorough drying. Avoid abrasive cleaners or solvents that could damage the aluminum finish.
- Lubrication: The swivel mechanism may benefit from occasional light lubrication with a silicone-based spray to maintain smooth rotation, especially if used in dusty or outdoor environments.
- Storage: When not in use, store the coupler in a clean, dry environment to prevent corrosion and damage.
- Replacement: If any part of the coupler shows significant wear or damage, replace the unit immediately to ensure safety. Do not attempt to repair damaged components that affect structural integrity.
6. Troubleshooting
This section addresses common issues you might encounter with the swivel coupler.
- Issue: Difficulty tightening the swivel bolt.
Solution: The central swivel bolt needs to be tightened securely to prevent unwanted rotation. If hand-tightening is insufficient, a wrench or pliers may be used carefully to ensure a firm grip. Ensure the bolt is not cross-threaded and that the components are aligned correctly before tightening.
- Issue: Coupler slips on the pipe.
Solution: Ensure the pipe diameter is within the specified 40-52mm range. Fully tighten the wing nuts on both O-clamps. The anti-slip hook and friction rings are designed to provide a secure grip; ensure they are properly engaged. If slipping persists, inspect the pipe and coupler for any debris or damage that might prevent a secure connection.
- Issue: Swivel mechanism feels stiff.
Solution: Loosen the central swivel bolt slightly. Clean any dirt or debris from the swivel joint. Apply a small amount of silicone-based lubricant to the moving parts of the swivel mechanism. Then, re-tighten the bolt to the desired tension.
