SBhaskar, Thank you for taking the time to leave us your thoughts on the Crestfield 48 in. x 70 in. Semi-Frameless Sliding Shower Door in Chrome with Mozaic Glass. I am sorry to hear that your grab bumpers are not holding the door in place, I know that must be frustrating. I have passed your comments along to a Delta Shower Door Specialist and they will contact you to see what solutions we have. I apologize for the inconvenience and appreciate your feedback. Best, Corinne at Delta Shower Doors
