Oca FX Key Features

Anatra locknuts

Based on community voting, the Oca uses locknuts to eliminate the need for threadlocker and ensure screws can't loosen.

Anti-slip pads are integrated into the mount. They are tough while being carbon rail safe. The back of the clamp also includes a tab that keeps the body and clamp in alignment for improved grip. Anatra clamp pads and alignment tab
Reduced device rotation The shape of the neck is designed to provide strength and clearance. We shaped the neck to accommodate the RCT715 and balance it for optimal performance which helps reduce jitter in the un-stabilized camera. This also adds greater stability for all other cameras as well as the other Varia radar models.
The one piece body and neck are incredibly strong and able to support the weight of the RCT715 Varia radar and pretty much any other camera you can throw at it that fits. Anatra neck changes

Saddle Compatibility

Reduced device rotation The Oca clamps to the lower part of the rails that are parallel to the ground. The minimum width is 35 mm (1-3/8") on the inside and 70 mm on the outside. The rails can be round or oval, but must be between 6.5 and 10 mm thick (most are). You must have 30 mm (1-1/4") of clearance between the rail top and the bottom of the saddle. The back center top of the saddle must be open and clear of obstructions.
The Oca is designed to accommodate rails that tilt inward at the back (TT saddles) as well as those that spread out like a 'Y' (Brooks saddles). As long as the clamp fits within the rail space, it is fine to clamp it there. Anatra neck changes

We source all raw materials, manufacture the primary components, assemble, and package the products in the United States. Some accessory items or minor components are imported (noted in the product details).

We currently ship within the U.S., most U.S. territories, and Canada. Please see the international shipping page for more details.
