A video about the new TD5 cylinder focuses on the importance of patented masterkeyings for security. TESA ASSA ABLOY has recently posted on its YouTube channel a video about one of the most recent launches: the TD5 cylinder. The TD5 is a patented cylinder that covers the basic segment of the ASSA ABLOY range of cylinders. Primarily designed for masterkeyings that do not require high security (although it includes medium antipick protection) but require the monitoring of copies of keys, which grant access to many cylinders. The video not only shows the features of the cylinder but also the benefits of using masterkeyings and monitoring the copies of keys, the exclusive service of 48-hour key duplication and masterkeying offered by TESA ASSA ABLOY to those customers who use the ‘Brujo’ software.
