Allow one closer for every 55 lbs of door weight or portion thereof. Fire rated doors also require one fire rated hinge for every 20″ of door height or fraction thereof. The calculation that requires more hinges is the total number of hinges required.

Recommended spacing for use of one closer is half the distance from the center line of the door to the center line of the top hinge. Please reference the hinge spacing drawing.

SOSS 218IC – Frequently Asked Questions

1) What is the SOSS 218IC Series 7 spring closer hinge used for?
The SOSS 218IC Series 7 is an invisible spring closer hinge designed for heavy-duty doors. It provides both concealed mounting and automatic closing action. Commonly used on entry doors, fire doors, and high-traffic commercial applications where aesthetics and reliable closure are important.
2) What door thickness does this hinge require?
The 218IC requires a minimum door thickness of 1-3/4 inches. This model is specifically designed for standard commercial door thicknesses. Verify your door meets this minimum before installation to ensure proper function.
3) Is this hinge handed or universal?
SOSS invisible hinges are typically universal and can be installed on either right-hand or left-hand doors. The 218IC can be adjusted during installation to accommodate different door configurations. Confirm handing requirements with your specific application.
4) What finishes are available for the 218IC?
SOSS hinges come in multiple finish options including satin stainless steel, bright stainless steel, and zinc finishes. The 218IC maintains the invisible design regardless of finish. Check specific finish availability for your project requirements.
5) What is the weight capacity of this hinge?
The Series 7 designation indicates this is a heavy-duty model designed for substantial door weights. Exact capacity depends on door size and installation conditions. Consult manufacturer specifications for your specific door weight and verify multiple hinges may be required for very heavy doors.
6) Does this hinge meet fire door requirements?
Many SOSS invisible hinges are available with fire ratings for use on fire doors. The 218IC may have fire-rated versions. Always verify fire rating requirements with local codes and confirm the specific model meets your fire door application needs.
7) What accessories are needed for installation?
Installation requires the SOSS routing template specific to the 218IC model. You'll also need appropriate wood screws and possibly mortising tools. The spring closer function is integrated, so no separate closer mechanism is needed.
8) How difficult is installation of invisible hinges?
SOSS invisible hinges require precise mortising into both door and frame. Installation demands careful template alignment and routing skills. Professional installation is recommended due to the precision required and difficulty of correcting mistakes in expensive doors.
9) Can the closing speed be adjusted?
The 218IC spring closer function provides consistent closing action. Some models offer adjustment capabilities for closing speed and force. Check if your specific unit includes adjustment features or if closing characteristics are fixed.
10) What doors work best with the 218IC?
The 218IC works well with solid wood doors, metal doors, and composite doors meeting the thickness requirement. Door must be structurally sound to support the mortised hinge installation. Avoid use on hollow core doors or doors with insufficient material for proper mortising.
11) Are there similar SOSS models to consider?
SOSS offers various invisible hinges in different sizes and capacities. Other Series 7 models may work for different door thicknesses. Compare specifications across the SOSS product line to find the best match for your specific application.
12) What field conditions affect performance?
Extreme temperatures can affect spring tension and closing speed. High humidity environments may require stainless steel finishes for corrosion resistance. Frequent use applications benefit from the heavy-duty Series 7 construction. Consider environmental factors when specifying finish and model.
