Question: The dimensions for this item show 1.75"H x 19"W x 21.5"D. At 21.5 inches deep it's more like a short box than just a filler panel. If it is a filler panel, and looks like the photo, I would think it's panel closer to 1/8 inch deep (thick). What are the correct dimensions? Is it aluminum or steel?
Answer: Thank you for your inquiry, The depth for this product (Belkin RK5031 1U filler panel) was listed incorrectly. These filler panels are a few millimeters in depth. I have updated this page to reflect that - thank you for your feedback! UPDATE: The RK5031 filler panels are made of steel. If you would like any recommendations based on your application, please feel free to contact your Server Racks Online sales representative.
