Libec Versatile length dolly for RT20C, RT30B, RT40RB, RT50B and RT50C

The Libec DL-5RB is a premium, adjustable tracking platform featuring custom telescopic extension arms. Engineered explicitly to bridge the structural differences between diverse seventy-five millimeter and one hundred millimeter leg structures, this configuration provides seamless studio mobility across multiple tripod classes.

Core Features & Practical Utility

• 7.3-Inch Telescopic Sliding Adjustability: Unlike standard fixed-frame tripods, each arm of the DL-5RB houses an internal, interlocking square aluminum sleeve. By loosening the leg-lock knobs, you can adjust the physical arm length across a 7.3-inch (18.5 cm) sliding window. This lets you widen the dolly's overall stance to secure wide-footprint hundred-millimeter heavy sticks, or collapse the arms inward to firmly lock onto narrow travel legs like the ultra-lightweight RT20C carbon fiber series.

• Universal Multi-Angle Spike Sockets: The perimeter tips feature adjustable, heavy-duty rubber retention loops. These straps twist and clamp onto the bare twin metal ground spikes of your legs. Because the receivers adapt dynamically, the dolly is fully cross-compatible with select third-party production tripods from Sachtler, Manfrotto, and Vinten.

• High-Grade 3.9-Inch Fluid Casters: The rolling array relies on oversized 3.9-inch (100mm) composite wheels that glide easily over minor floor surface obstructions like studio tape markers, shallow floor transitions, and extension lines.

• Foot-Activated Independent Braking: Every caster wheel is paired with a mechanical step pedal. Pressing down on the toggle locks down both the wheel rolling axis and the physical swivel bearing simultaneously, preventing frame drift during slow panning shots.

• Ergonomic Center Carrying Handle: The central junction triangle features a cutout carrying strap handle molding. When wrap-up time arrives, you pull the locking pins and lift straight up on the handle; the entire heavy-duty structure automatically collapses together flat into a tight 18.7-inch (47.5 cm) package for transport.

Operational System Tips for the DL-5RB Setup:

💡 The Step-Symmetrical Alignment Method: When scaling the DL-5RB out to match your tripod, never extend just one leg section to bridge the gap. Instead, loosen all three locking knobs and telescope each arm out progressively by equal measure using the internal indexed metal guidelines. Keeping the central triangular hub exactly dead-center below your tripod's fluid head bowl ensures your rig's center of gravity remains completely balanced during rapid, fast-arc tracking movements.

• Rubber Loop Pre-Check: Before locking your camera payload onto the fluid head, verify that the elastic safety wrap bands are snapped all the way down around the tripod spike base block. Ensuring a solid mechanical connection prevents a single leg spike from popping up out of its retention socket if you hit a cord track on the studio floor.
