This recall involves the Sanus Vision Mount model LF228-B1 wall mounts and Simplicity model SLF2. The wall mounts were sold for flat screen televisions. The model numbers can be found on the UL sticker on the wall plate.  The elbow joint components on the wall mount's arm do not fit together properly, causing the attached television to tilt and possibly fall when the television is adjusted. This could pose an injury hazard to a consumer.  The Sanus Vision Mount model LF228-B1 was sold through independent television mount dealers nationwide from June 2009 through July 2010 for about $450. The Simplicity model SLF2 was sold through Costco from June 2009 through July 2010 for about $200.  http://www.cpsc.gov/cpscpub/prerel/prhtml10/10326.html
