Adjust the upper strap to optimize the fit. After you have attached the strap to the metal hook, move the two sides of the strap further away from each other if you're using the wider, deeper Light Seal or bring them closer together if you're using the narrower, shallower Light Seal. This creates the ideal tension in the strap, ensuring the cover fits just right over the Light Seal and Cushion.
