The Fisher Spring Bar Assy A5322 is a component of a snowplow's trip spring system. This specific assembly is commonly found on 10' Commercial Blade Fisher plows and works in conjunction with other parts to allow the plow blade to "trip" or pivot forward when encountering an obstacle, protecting the plow and vehicle from damage. It is a critical part of the plow's safety and operational mechanism, ensuring that the blade can absorb impacts and return to its original position.
