A rebuilt Gripnail machine is an exceptional value. The controls have been updated, worn out parts have been replaced and the frame has been cleaned and painted. It looks brand new and is the simplest most reliable machine we have ever built. Many contractors purchase rebuilt machines for occasional duct-lining or as a backup machine for busy periods. Gripnail machines can also be used to fasten foil faced foam liners that cannot be fastened by weld pins.
Here is an example of how the Gripnail 660R was rebuilt:

New Improved Reliability
The 660R uses a PLC (Programmable Logic Control) and non-contact proximity sensors in place of pneumatic valves and mechanical actuators.
Easy To Operate
Just fill the feeder bowl with Gripnails, set the air pressure and step on the foot pedal. Drive up to 1,000 fasteners before refilling.
Standard 5 Foot Throat
Fastens large duct sections, reducing material handling.
Front Mounted Component Cabinet
Affords easy access for service needs.
Visual Load Cycle
Quickly confirms electronic functions.
Proprietary Drive Cylinders
Made from special alloys to withstand continuous pounding.
NEMA 12-Rated Electrical Cabinet
Protects electrical component to minimize machine down-time.
Lightweight Foot Pedal
Allows easy movement by operator; cord protector prevents damage.
Fast
Gripnails fasten instantly and this machine will stay ahead of the operator.
Uniform Fastening
Regulated air pressure and our own proprietary drive cylinders, consistently deliver the exact same impact, for perfect fastening every time.
Low Maintenance
Draining condensation from the air tank and filling the oil reservoir is the only routine maintenance required. The automatic oiler lubricates both cylinders and the sealed electronic components are maintenance free.
Compact
Place between work tables for efficient work flow.
