When replacing hinges and latches for walk-in refrigerators it is important to get an exact or comparable replacement part. The back of the part will stamped with a series of numbers and letters called a mold number. The back may also read “flush” or have the offset size (e.g. 1-3/4″). It is important to have that number on the back to ensure you get the proper replacement. Additionally, having the serial number of your walk-in (often located in the door jamb on the hinge side or in a corner inside panel) can be a huge help if you’re ordering the replacement part from the walk-in manufacturer or your parts supplier.
Walk-in cooler and freezer hinges are either flush or offset. The easiest way to determine which style you have is to place your hand on the outside wall of the walk-in and slide it towards the door. If the door stops your hand from moving across the door, then you have an offset door. If your hand slides across the door, it is flush.
Determine the offset measurement by measuring from the wall surface to the door surface. The offset measurement combined with the mold number on the back will ensure you receive the correct hinge.
