this is a gray plastic dryer rack from my samsung dryer. bought approx 15 years ago. just purchased a new washer/dryer set. cannot find any numbers on this piece. width is 13  1/8''. length is 26.75'' to the longest section of one end.( small piece that sticks out ). shorter one is  24.5.''  did not use all that much but is a great feature for items such as drying sneakers. stored next to unit so i apologize for the dust between the 'squares.'  will refund some postage if less than charged. enlarge the photo of higher side....some of the sections that come out from the high piece are bent, one more so than the others.
