This video demonstrate how to adjust the waist belt of your Slinger Straps ergonomic guitar strap. Release the extra waist belt material from the slider on the waist belt by pulling the loose end through the slider and then position the buckle 90 degrees to the waist belt to allow the material to slide through the buckle freely. Tighten or loosen the buckle accordingly until you find the right length. Once the desired length has been found, slide the slider back in to a position where it can capture the remaining material for a cleaner look. If the remaining material is too long you can trim the waist belt with scissors and then seal the cut end with a lighter in a well ventilated area, keeping the smoke away from eyes and lungs (lightly, similar to sealing a nylon rope).
