High Speed
Button Lock

Flagler-Hi-Speed-Buttonlock Also referred to as a Snaplock Machine used in the same way as the Pittsburgh Lock for connecting the Longitudinal side of rectangular duct. Though not as strong of a lock as a Pittsburgh, it is SMACNA approved as an alternate method. It's advantages over a Pittsburgh are that no additional hammer over operation is required and thus no loud Air Hammers are in seaming the connection. Also, the duct can be nested and taken to job site, then assembled there. 20- 28 Gauge duct 100-ft. per minute. Spec Sheet
