When you combine the Libec QH3 fluid head with the T150B legs and the SP-15B ground spreader, you build the exact layout of the premium Libec QD-30 Field Tripod System with Floor Spreader.
This system package strips away the mid-level spreader and rubber feet in favor of absolute structural rigidity when operating large, front-heavy camera payloads on perfectly flat surfaces (like studio floors, linoleum stages, smooth pavement, or track platforms).
Component Function & Integration
1. Structural Interface: Native Flat Base to 150mm Bowl
Because the flagship QH3 fluid head natively utilizes a studio 4-bolt flat base, you mount it to the massive 150mm bowl of the T150B legs using the Libec BL-150 half-ball adapter. This enables high-load leveling capabilities without stripping the head down when transitioning from pedestals to field sticks.
2. Low Center of Gravity: The SP-15B Floor Spreader
The SP-15B is a heavy-duty ground spreader meticulously engineered for the wide-gauge feet of T150 series heavy tripods.
-
Anti-Splay Engineering: It anchors directly to the cast spikes at the absolute bottom of the tripod legs, transforming the footprint into an immovable triangle. This setup completely eliminates leg splay under a massive 60 kg (132.3 lbs) broadcast camera setup.
-
Telescopic Radial Tuning: Each arm of the SP-15B features independent extension tracks locked down by robust turn-knobs. This lets you flatten the tripod lower to the floor for low-angle lens heights while ensuring the wider footprint adds proportional tip-over safety.
-
Quick-Collapse Center Ring: Features an integrated center pull-ring, enabling you to lift and collapse the entire 40+ pound tripod framework inward symmetrically in one clean upward pull.

Ground Spreader Operational Pro-Tips:
⚠️ The Flat Surface Baseline Rule: The SP-15B ground spreader should only be deployed on stable, flat surfaces. If you are operating on steep hillsides, rocky slopes, stadium bleachers, or uneven stairs, you should swap the SP-15B out for a mid-level spreader (BR-6B) and rubber feet (FP-6B). Forcing a ground spreader onto jagged terrain causes the arms to twist off-axis, loading uneven bending force onto the tripod's bottom castings and increasing the risk of a top-heavy rig tipping over.
-
Managing Box Lenses: When operating long box lenses near the 60 kg limit with this system, extend the SP-15B arms to their maximum outer radius. This wide stance maximizes structural dampening, eliminating micro-shakes at the tail end of aggressive pans when shooting at high focal lengths.
