Libec Extra Long Plate for LX10 Head, RHP75 and RHP85

The Libec Long Sliding Camera Plate (Official SKU: Long Plate L) is an expanded, high-capacity hardware accessory engineered specifically for Libec's robust 100mm bowl professional fluid head systems. Its core mechanical purpose is to dramatically extend the shifting balance window for heavy broadcast and digital cinema cameras that possess asymmetrical weight distributions—such as setups utilizing oversized zoom lenses, front-heavy matte boxes, or heavy V-mount battery systems on the rear.

Universal Cross-Compatibility Mapping

The primary design achievement of this plate is its drop-in compatibility across Libec's high-capacity production and broadcast lineups. It integrates directly with the following specific heads:

• High-Capacity Production Fluid Heads: Libec LX10 and LX10 Studio

• Flagship Heavy Broadcast Series: Libec RHP75 and RHP85 (from the heavy-duty RSP system ecosystem)

• Cross-Platform Compatibility: The physical dovetail profile is also broadly cross-compatible with select Manfrotto and Sachtler fluid head receiving channels that share the same standard design width.

Core Engineering Features

1. Extended Shifting Window

Measuring 240mm (9.4 inches) in total length, the Long Plate L provides a massive active sliding range of 95mm (3.7 inches) forward or backward from center. This long horizontal track enables camera operators to offset severe front or rear leverage issues without needing to screw on cumbersome counterweights or rail extensions.

2. Dual 3/8"-16 High-Load Rigidity

Unlike smaller plates that rely on single-point indexing pins, this broadcast-grade plate comes standard with two heavy-duty 3/8"-16 camera tie-down screws sitting in an extended parallel slot track. This allows large-format cinema camera bodies, baseplates, or studio prompter cages to be anchored at two separate structural points, completely eliminating the risk of twisting on the plate surface under high pan and tilt torque.

3. High-Contrast Side Measurement Scales

The left and right outer flanges feature laser-etched metric measurement marks. This calibration index allows camera operators to quickly note down the exact numerical alignment point for specific camera-and-lens packages. When swapping configurations in the field, you can return the camera package to its perfect center-of-gravity balance spot on the head in seconds.

Operational System Tips for the Long Plate L:

💡 The Dual-Screw Mounting Track: Because this plate is optimized for heavier cinematic loads, it utilizes two wide 3/8"-16 screws rather than the standard 1/4"-20 size. If you are mounting a camera system that only features 1/4"-20 threads on the bottom, ensure you use a dedicated heavy-duty camera cage or a structural baseplate adapter that converts those smaller lines into robust 3/8"-16 mounting holes for maximum safety.

• Managing Perfect Balance Steps: When deploying a full broadcast setup on an RHP75 or RHP85 head, first mount the Long Plate L loosely to your camera package. Slide the camera into the head channel, loosen the head's pan and tilt locks, and slide the rig until it stays level on its own at 0 degrees tilt. Lock down the head's quick-release side lever securely, slide the camera back off, and use a screwdriver or flat tool to tighten the bottom 3/8"-16 screws completely.
