The Consumer Product Safety Commission has announced the recall of one million trampolines and nearly $300,000 trampoline enclosures. The agency says welds on the trampoline frame can break, and mounting brackets on the enclosures have sharp, cutting edges. The recalls follow reports of dozens of injuries, including serious lacerations and a concussion. The Texas-based Jumpking Incorporated sells the 14- and 15-foot trampolines alone or with the enclosures. The two products were sold at discount department and toy stores in the U-S and Canada from July 1999 to February of last year. Consumers are advised to stop using the trampolines and enclosures. They can contact Jumpking (866-302-8669) for free repair kits or more information.
