We offer three types of Single Loops to best suit your needs: Standard D-Ring, Padded D-Ring, and SoftTouch Loops™.D-ring loops attach to ropes with snaps, such as Studio Reformer Replacement Ropes with Clips. SoftTouch Loops feature a quiet attachment point and are designed for use with SoftTouch™ Ropes. All Single Loops are the same length. Padded options are made with thicker material for added comfort. For faster transitions, you can also attach a handle to the second D-ring on your Reformer footstrap using a carabiner or snap. This keeps the handle in place during exercises that require a footstrap, so you don’t have to reattach it each time. Wash loops regularly in cold water and air-dry. Note: All sales of Loops are final and non-returnable.
