Thank you for your feedback. The Unidoor does not have rollers, however. The hinges that are included are designed to hold much more than the weight of the glass panel. If you glass is slipping in the hinge, that tells us that the hinges were not tightened enough from the inside of the shower. We invite you to contact our DreamLine Customer Support Team at 866-731-8378 to discuss this further. We can also be reached by sending an email to support@dreamline.com. Our hours of operation are 8am-6pm EST, Monday through Friday. Thank you for your interest in DreamLine.
