PowerPinner® 50

Most coil lines are capable of running at 50 feet per minute, but had to slow down to 25 ft/min. when applying welded duct liner fasteners. Gripnail introduced the industry's first 50 ft/min. two decades ago. Ever since we have been centered on continuously making industry leading improvements to the design. The PowerPinner 50 is capable of placing full range of weld pins up to 2" as close as 6" apart to metal as thick as 16 gauge without any extra modifications.

Sam Replacement Controller at KJ Machinery Sales

Sam Replacement Controller
for Coil Line Pinners

Gripnail's new spacing acquisition module (SAM) provides a way to retrofit coil lines with a new pinner, regardless of the vintage or condition of the coil line controller

SAM is mounted on the frame of the coil line and "reads" the edge of the metal with through-beam fiber optic sensor that detect the notches and an encoder that measures the distance between the notches. These two pieces of information are fed into a PLC which calculates the pin spacing for each duct panel.
