This has always bugged me, when items slip thru the Bed extender and ricochet off the front wall of the bed. When a bottle of Antifreeze did this I finally did something about it. I ordered netting P/n S1250 8 foot long X 2 foot wide. This will be Qty. 0f 16. The netting edges are finished. It was $35.20 plus $15.00 Shipping & Handling* I attached the net on the outside of the cage with 44 - 7 inch wire ties, that grabbed two web cords and left three squares at the top and bottom. I may go and redo this with shock cord. At each end I left one square. This was ordered from National Tool Grinding, Inc. 1-800-331-2973 or www.usnetting.com . Fax 814-455-9336 *I spread out the S & H by ordering three nets at the same time!
