Mounting Where Others Can’t
When the X-ray table surface isn’t the right spot for your marker, the OM-1011 offers the flexibility to mount directly to the equipment itself. This large clamp base is engineered to provide a stable, customizable reference point by attaching to existing handles, rails, and supports within the imaging environment.

Why a 25.4 mm Calibration Sphere?
Surgical templating software needs a known reference object in the image to calculate magnification. A 1-inch (25.4 mm) solid sphere is the standard because it presents the same diameter regardless of imaging angle — unlike a disc or coin, which can appear elliptical if tilted. Position it at the anatomical plane of the joint, and the software does the rest.
Why Choose OrthoMark?
OrthoMark has been the trusted name in surgical magnification markers for over 20 years. Our commitment to solid 316 stainless steel calibration spheres and durable, American-made mounts ensures that your templating software receives an undistorted, reliable reference every single time, regardless of the environment.
Need a Different Mount?
Every OrthoMark uses the same 25.4 mm calibration ball and adjustable arm. If the clamp isn’t the right fit for your facility, check out our other options:
