Rifton initiated recalls for TRAM and E-Pacer units due to an unrelated buckle spring failure, which led to replacing the full body support strap assembly. for that recall, rifton ordered a large batch of aluminum stampings (DA53). Because of the unusually large order, the supplier used a different manufacturing process, resulting in some stampings having sharper strap openings. over time, these sharp edges can abrade and fray the straps, and if not addressed, may cause the strap to fail, creating a fall risk for the user.
