Suction Stability & Ease of use
The OM-1009 is built for easy, single-handed operation with very strong suction in a small footprint. The 2.75″ lever-action base is designed to engage fully on smooth surfaces and those that aren’t perfectly smooth.
Full Specifications
- Base type: 2.75″ lever-action suction cup
- Surface: Smooth, non-porous, and slightly dimpled surfaces
- Arm length: 24″
- Product weight: 12.4 oz
- Ball: 25.4 mm (1″) solid 316 stainless steel
- Warranty: 1 year against manufacturer defects
- Country of origin: Designed and assembled in the USA
Note: As with all rubberized mounting materials, we recommend periodic cleaning of both the suction cup and the mounting surface to maintain optimal grip. Avoid use on “sandy” or highly porous surfaces.
Common Clinical Applications
- Demanding Imaging Suites: Perfect for tables with slight surface texture where standard suction might slip.
- Reliability-Focused Environments: The lever-action provides visual and tactile confirmation of a secure seal.
- Surgical Planning: Ensures the marker doesn’t shift during high-precision X-ray sequences.
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 your imaging surface requires a different approach, check out our other options:
