Bernina Q Series Mechanical Channel Locks

The BERNINA Q Series Mechanical Channel Locks are a precision accessory designed for longarm quilters who need perfectly straight lines, consistent stitch density, and repeatable results across every project. Compatible with BERNINA Q Series longarm quilting machines, these channel locks restrict machine movement to a single axis — horizontal or vertical — so you can execute straight-line quilting, crosshatch grids, and geometric designs with accuracy that freehand movement simply cannot match.

Key Features

• Mechanical channel locks restrict machine movement to a single axis — horizontal or vertical — for precise straight-line quilting.
• Dual-axis control allows you to lock horizontal and vertical movement independently, giving you full flexibility over your quilting direction.
• Designed specifically for BERNINA Q Series longarm quilting machines for a secure, properly fitted engagement.
• Smooth mechanical engagement and release make it easy to switch between locked and freehand quilting modes during a project.
• Eliminates drift and wobble when stitching in the ditch, outlining blocks, or quilting uniform parallel lines.
• Supports consistent quilt density across large quilt tops by keeping stitch lines evenly spaced and parallel.
• Durable mechanical construction is built to withstand the demands of high-volume and professional longarm quilting use.
