Tilta 50mm Speed Rail Adapter for Hydra Arm Mini Shock Absorbing Arm

The Tilta HDA-T08-SRA is a rugged, black-anodized aluminum 2″ speed rail adapter that securely mounts the Hydra Arm Mini shock-absorbing arm onto any standard 2-inch (50.8 mm) outside-diameter speed rail or scaffold tubing, delivering dramatically higher payload capacity and rock-solid stability compared to suction-cup bases – essential for professional camera-car rigs, process trailers, grip trucks and overhead studio setups.

Designed for demanding vehicle and studio applications, the HDA-T08-SRA replaces the suction-cup or host-grip base of the Hydra Arm Mini with a heavy-duty split-clamp that locks onto 2″ speed rail (Schedule 40 pipe). The dual-bolt clamping system ensures zero movement even under extreme vibration or high-speed driving, while the CNC-machined aluminum construction keeps weight low and durability high. Perfect for mounting heavier cinema cameras on chase vehicles, low-loader arms or fixed overhead rigs where suction is not viable.
