Channel locks are available for most Q'nique and Grace Frame Combinations. You will need to order two if you want a lock on both your carriage and your frame for both y and x axis. Please let us know which frame and which machine or carriage you are using. Purchase one channel lock to be fitted to your Q'nique 14/15/19 machine, and a second channel lock to be added to your G-Series carriage. If you have a SR2 frame with the Pro Carriage, you can still purchase one channel lock only to be installed onto your Q14/15/19 which will allow you to straight line quilt along your x-axis or left to right quilting. If you have the SR2 frame with the G-Series carriage order two for both x and y engagement.
Please contact the shop directly if you are unsure if these will work for your set up.
