Invisible Hinge Closers SOSS 216IC Series, Satin Chrome

SOSS 216IC Invisible Hinge Closer For Clean Door Control

SOSS 216IC invisible hinge closer is a modified standard Soss hinge that adds a 3/8 inch baseplate and an easily adjusted spring, so it functions as both a hinge and a closer and reduces the need for a separate closer component on the door. The closer rate is completely adjustable after installation without removing the closer or any parts, which keeps fine-tuning on site straightforward once the door is hung and operating under real conditions. This closer is designed for door thickness up to 1-3/8 inch, giving a clear thickness guideline when selecting hardware for interior doors within that range. It is made of heavy-duty zinc alloy castings, which supports a solid feel in the leafs and body under repeated use. The finish is satin chrome, aligning the closer with satin chrome hardware sets where a concealed closer is preferred.

Key Working Details Of This Invisible Closer

• The standard Soss hinge has been modified to permit a 3/8 inch baseplate, which changes the mortise depth requirements and provides the structure needed to carry the closer mechanism within the hinge body.
• An easily adjusted spring is built into the closer, allowing controlled closing force to be set to site conditions so doors can return consistently without removing the closer for changes.
• The closer functions as both hinge and closer, which removes the need for an additional separate closer on the door edge and keeps the opening visually clean while simplifying hardware layout.
• Closer rate is completely adjustable after installation, giving installers the ability to fine-tune door closing behavior once hinges, latch, and seals are already in place.
• For door thickness up to 1-3/8 inch, the closer matches common interior door builds, helping installers pair it with doors that stay within the stated capacity.
• Made of heavy-duty zinc alloy castings, the closer body is built from a rigid casting that supports hinge action and spring closer function under repeated cycles.

Installation And Mortise Changes For The SOSS Closer

In retrofit applications, the mortise depth must be increased 3/8 inch and one hole drilled to allow for insertion of the spring into the door, so an existing standard Soss hinge prep needs additional depth and a specific spring cavity for this closer. The closer rate is completely adjustable after installation without removing the closer or any parts, so once the deeper mortise and hole are prepared, door behavior can be dialed in from the installed position. The closer is specified for door thickness up to 1-3/8 inch, guiding layout when planning edge preparation and hinge spacing on compatible doors. The modified standard Soss hinge format means installers familiar with Soss invisible hinges work with a recognizable footprint while allowing for the added closer function.

How This SOSS 216IC Closer Works On The Job

Using The Invisible Hinge Closer On 1-3/8 Inch Doors

This SOSS 216IC invisible hinge closer is designed for door thickness up to 1-3/8 inch, which targets typical interior doors where a concealed closer is preferred instead of a surface-mounted closer. The closer functions as both hinge and closer, so it carries the door while also controlling closing, which can streamline hinge locations because one unit fills both roles in the opening. The standard Soss hinge has been modified to permit the inclusion of a 3/8 inch baseplate and an easily adjusted spring, giving the closer a structural base and internal spring that sit inside the door and jamb leaves for a fully recessed installation. Because the product is made of heavy-duty zinc alloy castings, the hinge-style closer body maintains a solid feel during swinging and closing cycles on doors built within the stated thickness range.

Adjustment, Retrofit Mortise Work, And Repeatable Results

The closer rate is completely adjustable after installation without removing the closer or any parts, so installers can set closing speed or force in response to site conditions such as latch drag or air movement with the door already in service. In retrofit applications, the mortise depth must be increased 3/8 inch and one hole drilled to allow for insertion of the spring into the door, which means an existing Soss hinge prep gets expanded to house the baseplate and spring hardware in a way that supports consistent closing action. The modified standard Soss hinge layout, combined with the 3/8 inch baseplate, keeps the closer fully concealed in the mortised pocket, which helps maintain a flush edge detail when the door is closed. Heavy-duty zinc alloy castings support stable alignment between the leaves, which promotes repeatable swing and closer behavior over time when installed in doors that fit the stated thickness guideline.

Common Questions About The SOSS 216IC Closer

Selecting This Closer For Concealed Door Control

The SOSS 216IC satin chrome invisible hinge closer combines a modified standard Soss hinge body with a 3/8 inch baseplate and an easily adjusted spring, so it both supports and closes doors up to 1-3/8 inch thick in a fully recessed format. Its closer rate remains adjustable after installation without removing the closer or any parts, so final door behavior can be tuned at the opening. Heavy-duty zinc alloy castings and the satin chrome finish align this closer with interior hardware selections where concealed operation and a consistent closing action matter.
