Geared to the Safety Glasses industry, this time tested, proven reliable machine installs a self-locking pin developed by SPIROL into the assembly.
This innovative pin, called the Twist-Lok™ Pin, replaces commonly used threaded screws as the hinge pins in the temples of the glasses.
Screws are generally known to be more expensive, difficult to install, and subject to working their way out of the holes. SPIROL®Twist-Lok™ Pins are simply pressed into the holes, and they create a tight hinge connection that will not work itself loose over time.
The machine is lightweight, portable, low-cost and features simple head center distance adjustment to accommodate different width glasses.
