Secure vertical positioning ABS Holster for Dino-Lite microscopes. This holster allows Dino-Lite microscopes to be snapped into place and held snugly by the edges of the magnification dial. The MSA3HL provides a great solution to aligning the viewpoint of the Dino-Lite to the screen, holding the scope in the position that provides appropriate verticality on screen. This secure positioning holster also prevents height slippage making the height consistent in usage. Proper use of this holster is with the magnification dial exposed and the holster ‘snapped’ into the edges of the magnification dial opening.
