Product Information

Full details

The Sirui PH-120 Quick Release Plate is an essential accessory for professional photographers using the Sirui PH-20 Gimbal Head, specifically designed to provide stability for long, heavy telephoto lenses. This 120mm Arca-compatible plate offers a secure mounting solution that prevents equipment rotation and accidental slippage, making it a reliable choice for wildlife and sports photography; however, users should note it is specifically engineered for the PH-20 system and may not be optimal for all universal Arca-type clamps without verification.

Extended Product Information

FAQs

Is this plate compatible with other tripod heads?

The PH-120 is Arca-compatible and can fit many universal Arca-style clamps, but it is optimized specifically for the Sirui PH-20 Gimbal.

What is the primary material used?

The plate is constructed from high-quality, lightweight aluminum for durability.

Can I remove the stop screws?

Yes, the stop screws can be removed if they interfere with specific clamp designs, though this reduces safety against accidental drops.

Does it include both screw sizes?

The plate supports both 1/4 and 3/8-inch threads to accommodate different lens collar specifications.

How much does the plate weigh?

The PH-120 weighs 70 grams.

Troubleshooting

Plate does not slide into the gimbal clamp

Check if the safety stop screws on the underside of the plate are hitting the clamp edges; you may need to loosen the clamp further or remove the stop screws temporarily.

Lens rotates on the plate

Ensure both mounting screws are tightened properly or utilize the raised rear ridge to brace against the lens mount collar.

Plate feels loose in the clamp

Verify the Arca-clamp tension and ensure the anti-slide mats are clean; dust accumulation can prevent a flush, secure fit.

Pros and Cons

Pros

  • Durable lightweight aluminum construction
  • Enhanced safety features prevent accidental drops
  • Dual 1/4 and 3/8 inch screw support for versatility
  • Long profile balances heavy lens weight distribution

Cons

  • Specifically optimized for the Sirui PH-20 Gimbal Head

  • Requires manual adjustment of stop screws for some third-party clamps

Setup, Compatibility & Care

To install the PH-120, align the 1/4 or 3/8-inch screw with your lens collar mount and tighten securely using the provided mounting holes. If using a lens with dual mounting sockets, ensure both screws are utilized for maximum rigidity.

Compatibility

  • Designed primarily for the Sirui PH-20 Gimbal Head.
  • Compatible with standard Arca-Swiss type quick-release clamps.

Care Instructions

  • Clean the aluminum surface with a soft, dry cloth to remove dirt or debris.
  • Periodically check that the anti-slide mats are clean and free of dust for the best grip.
  • Regularly inspect the stop screws to ensure they are tight and properly positioned for your specific clamp width.
