Alpha has re-designed and improved the already popular Alpha Guide Rail and Carriage System designed for the AWS-125 stone cutter, which made the precise cutting application easier. Now, the new Guide Rails have a track for the new Carriage System wheels to ride along to ensure a smoother, more precision motion. Due to this, the Guide Rails are not only used for cutting applications but also for beveling and polishing. It is an ideal system for the preparation of seamless countertop installations. 

The guide rails come in lengths of 4’, 7’ and 12’. Typically, the 4’ is the most popular for the trimming application of countertops at the job site. The 7’ and 12’ lengths are designed for slab cutting, bevel grinding, and polishing on the main edges of countertops. Alpha offers an assortment kit with all three lengths, at a cost savings.  

The 5” Guide Rail Carriage Assembly (ASC-5CSM) is designed for new ESC-125 Wet/Dry Stone Cutter only. This system allows you to cut straight only.  

The 6” Guide Rail Carriage Assembly (ASC-6CSM) is designed for the PSC-150 Wet Stone Cutter for straight cuts as well as miter cuts. This carriage has three templates included that assist the install of the stone cutter for left side or right side miter cutting and straight cutting. 

The Carriage Assembly for Beveling Auxiliary Base (BAB-CASM) is designed for the Beveling Auxiliary Base (BAB1590) to assist the precision grinding, beveling and polishing applications.  

During the use of the Alpha Guide Rail System, we suggest using the Surface Protection Tape (BAB0650) to protect the surface from potential scratches.
