Mechanical Channel Locks
Mechanical channel locks make it easier to sew in perfectly straight lines and are also useful for straightening the top of a quilt and simultaneously tacking it at the edges onto the batting and the quilt back. Channel locks are mounted directly onto the X and Y axes of the quilting frame. They block the movement of the carriage and therefore that of the machine in either a horizontal or vertical direction.
More information about longarm quilting frames is available on the BERNINA Q 24 product page.
