Tilta Hydra M25 Mounting Bracket for Electronic Suction Cup (4.5″)

The Tilta HDA-HMB bracket with a Hydra M25 thread bolts onto the Hydra 4.5″ electronic suction cup with four M4 screws. The cup then takes the dovetail plates of the Hydra Alien system just like the system's own cups — only with a vacuum it monitors itself. The joint under the thread tilts, so the plate sits flat even on curved bodywork. The bracket is aluminium alloy, black.

The Tilta Hydra M25 Mounting Bracket is one of three interchangeable brackets for the Hydra 4.5″ electronic suction cup, alongside the NATO rail bracket and the multi-functional bracket with a rosette. It carries a collar with the M25 thread by which the dovetail plates of the Hydra Alien system attach to their suction cups. A 3 mm Allen key for swapping is included.

Straight onto the 4.5″ electronic suction cup

The bracket sits on the top face of the Hydra 4.5″ electronic suction cup and is held by four M4 screws. The joint is as rigid as a fixed mount, yet the included 3 mm Allen key takes it apart to swap for another bracket in the range — the NATO rail bracket or the multi-functional bracket with a rosette. The cup from any Hydra kit with the 4.5″ electronic cup thus serves several rigs.

M25 thread on a tilting joint

On top is a collar with the Hydra M25 thread — the interface by which the dovetail plates of the Hydra Alien system sit on their cups. The collar stands on a joint that tilts and locks with a screw, so the plate stays level even on a domed bonnet or a sloping pillar. The electronic cup monitors its own vacuum and tops it up when it drops — a base under the arm you do not have to keep an eye on while driving.

The Tilta Hydra system

Hydra is Tilta's modular system for shooting from moving vehicles: an electronic suction cup that monitors its own vacuum, the damped Hydra Alien and Hydra Alien Mini arms, speed rail kits for the bodywork and brackets for monitors, cameras and accessories. The parts combine through shared standards (4.5″ suction cup, M25, NATO, 1/4″-20, speed rail) — this one is among them.
