The exact hardware match for a Libec 100mm ball video head natively compatible with the PH-8B pan handle that supports a 25kg payload is the flagship Libec RHP85 Professional Fluid Head.
Core Capabilities of the Libec RHP85
-
Continuous Perfect Counterbalance: Rather than using step-based increments, the RHP85 features a fully variable micro-adjustable internal spring tension mechanism. While its absolute max payload threshold is 25 kg (55 lbs), it provides a perfect counterbalance sweet spot for camera packages weighing between 9 kg and 20 kg (20 to 44 lbs). When calibrated correctly, a heavy broadcast rig will freeze completely at any tilt angle when you release the handles.
-
7-Step Mechanical Drag Control: Equipped with independent 7-stage smooth pan and tilt fluid switches (plus a true zero-drag bypass), providing predictable, high-precision mechanical resistance during slow tracking moves or immediate panoramic action.
-
Wobble-Free Balance Stabilizer: Features an internal bearing architecture specifically targeting and neutralizing "pan backlash"—the micro-wobbles or horizontal spring-back shifts that typically occur when a heavy telephoto configuration comes to an abrupt halt.
-
One-Touch Sliding Plate Mechanism: Includes an extra-long sliding camera plate (Sliding range: $\pm$55mm) that drops straight down into the platform and snaps locked instantly, dramatically speeding up balancing setup for complex studio configurations.

System & Handle Customization Notes:
-
Dual-Handle Setup: The RHP85 head includes dual rosette mounts. Pairing the head with 2 pieces of the PH-8B handle creates a standard studio broadcast layout. This allows the operator to mount electronic lens zoom demands to one handle and focus demands to the other for traditional live studio ergonomics.
-
Alternative Legacy Head: If you are sourcing used or older legacy gear, the classic Libec H100 also shares a 100mm bowl base and a 25kg capacity, but uses older variable fluid modules and ships with the non-telescopic PH-7 pan arm. The RHP85 remains the modern standard choice.
