Magnescale GBP Series have been around for at least 20 years and is a very durable scale. The GBP scale is a magnetic scale that holds up in difficult environments. Coolant, chips, dirt and dust are typically no problem for the GBP scales
This scale is ideal replacement for SR50 or SR30 series scales. For the SR50 and SR30 series, you will need to drill new mounting holes for the scale. However, you can use your existing cable that you have for the SR50 or SR30 series scale.
The GBP series was developed for some OEMs, such as Gerber Coburn.
