Master Lock Company LLC has introduced a short and clever 30-second video via social media to promote the upcoming release of a revolutionary new institutional locker lock. The product will reach the marketplace next month and the spot can be viewed on Facebook www.facebook.com/masterlocksecuritysafety, Twitter www.twitter.com/mlsecuresafe, YouTube www.youtube.com/user/MasterlockCompany, and at LinkedIn www.linkedin.com/company/master-lock-locker-lock. The humorous spot puts a lighthearted spin on the hard work school maintenance workers face when handling the daunting task of changing locker combinations. The voiceover announcer acknowledges their importance and teases how the new lock will make the work day easier. This is the second product Master Lock has launched for the locker lock category this year that focuses on reliability and convenience. The Multi-User lock released in January is designed for use in facilities with multiple customers using the same locker throughout the day.
