Detailed Product Description

The Hejnar Photo Index Stop Bar is an elegant solution for photographers who need to move their gear between setups without losing their critical alignment. In complex disciplines like panoramic photography, marking your no-parallax (nodal) point is essential for consistent stitching results. This stop bar marks that exact point on your nodal slide, allowing you to reassemble your panoramic rig in the field with mathematical precision.

Protection for your high-end hardware is paramount. Unlike standard metal-on-metal stops, this bar is equipped with soft tip screws. This allows you to apply the necessary torque for a secure, unyielding hold while ensuring your rails remain free of unsightly scratches or surface damage. Whether you are using it on a 10-inch or 14-inch rail, the bar maintains a low-profile presence while providing maximum security.

Machined from solid aircraft alloy and finished with a rugged hard-coat anodize, this USA-made accessory is built for professional longevity. It is a highly practical, modular asset that accelerates your workflow efficiency by removing the need for repeated measurements during setup.
