A weld between the "VESA" style mounting plates and the mounting ring can fail, which can result in a television or a monitor falling, possibly injury bystanders, the Consumer Product Safety Commission said in a statement.
The wall mounts were imported from China by Ergotron Inc., and sold nationwide from February 2012 through January 2013 for between $50 and $400.
Eight models of the wall mounts are involved in the recall, including the PLAY40, PLAY40DS, PLAY70, ITV-HD, ITV-VHD, OM80FM, OBFM120 and OBFM60.
The model numbers can be found on the underside of the arms of the PLAY and ITV models, the commission said.
Consumers were advised to remove the television or the monitor from the wall mount system and contact Ergotron for a free repair kit.
Consumers can call 800-888-5458 for information.
