International Cold Storage 21112 Sureclose Hydraulic Door Closer

The International Cold Storage 21112 Sureclose Hydraulic Door Closer is a movement control component used in walk-in refrigeration and cold storage doors to guide closing action during operation. It is installed between the door frame and door panel, where hydraulic resistance controls the closing speed after the door is opened. This door closer integrates with mounting brackets and hinge assemblies used in refrigerated storage conditions. It is commonly found in commercial cold storage systems, it is typically performed during servicing when closing resistance weakens or movement becomes uneven, allowing continued door operation within refrigerated applications.
