I assure you that Sears tries to provide as much information as they can for online purchases, however all descriptions are provided by the manufacturers of the items. That why you'll often find the same descriptions across several sites if the item is available from other stores.
I do apologize for the inconvenience and would be happy to help you find what you're looking for if you have a specific type of tarp you need.
I hope that helps! If you need help in the future, I can help you find coupons, discover lower prices and answer product questions! You'll also receive a welcome email with a coupon for $5 back in points on your next $25 purchase at Sears or Kmart. Click this link: syw.co/sywmakobi
