This Avantco brass hinge spacer is a direct replacement for the one that came with your unit. It is a vital part of your unit's door assembly, working to keep your unit in top condition. A broken or malfunctioning door can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace any broken parts promptly. It's compatible with the bottom door hinge on select Avantco A and SS series reach-in units.
