Medical Bearings on Markar Hinges Markar is pleased to announce enhancements to its continuous pin and barrel hinge line. On August 1, 2012, Markar began providing Medical Bearings as standard on all 200/300 series continuous pin and barrel hinges at no additional cost. In October we implemented the change on the 100/3500 series continuous pin and barrel hinges. As of November 1, 2012, Medical Bearings are standard on all Markar continuous pin and barrel hinges. This new standard provides permanently lubricated hinges with no metal-to-metal contact, improving the life and overall function of the hinge. At Markar, we strive to continually produce the most innovative and best performing products in the marketplace. We value our partnership with you and appreciate your feedback.
