Includes five glass stops, enabling you to save more size settings with your Portable Glass Shop (PG15B and PG01B).
Five Glass Stops per package.
The Glass Stops make it easy to save critical size settings while working on a project. Many Portable Glass Shop users say that they just can't have too many extra Glass Stops.
To save a size setting, add a small strip of masking tape to the Glass Stop, record the column number in relation to the black knob and circle it. After adding the size to the tape you can remove and replace the stop to the exact same setting. (Refer to photo above)
