Installation Guide

Installation Using the Paper Template
1 Make the required measurements on both the door and jamb
where the hinges and closer shall be mounted. Make certain that
clearance is provided between the top of the door and the jamb
to permit free movement of the door after installation,
Note: It is recommended that the SOSS Invisible Closer be
mounted such that the spring-bearing portion of the hinge
is situated in the door.
2 Fold the paper template along the fold line
on the template. Note: There is a top for
left handed doors and a top for right
handed doors.
3 Using a punch or similar object, punch holes
into the door at the locations marked by the
drill-point indicators (crosshairs). Note the
drill-point indicator marked with an X. This
is the point where the clearance hole for the
spring must be drilled.
4 Remove the template from the door prior to doing any drilling.
WARNING:
It is imperative that all drilling be done with the utmost
precision and care. Special attention must be directed to the
drilling of the spring clearance hole. You will be required to
drill a relatively large diameter hole over 7" deep (in the case
of a solid-core door). Special precautions should be taken to
assure that the holes you will be drilling are perpendicular to
the mounting surface.
5 At the punch point corresponding
to the X, a small diameter hole
(approximately 1/8" diameter or less)
should be drilled at least 2
3
/4" deep.
NOTE: This is the start point for
the eventual drilling of the spring
clearance hole. The spring clearance
hole will be drilled after the hinge
mortise has been formed. Do not drill
through it, or you will have to visually
ascertain it's location at a later time.
Drilling of Hinge Body Mortises
6 At the punch points marked with A,
drill the required size holes to the
depths listed below by hinge size.

IMPORTANT
NOTICE
SAFETY
Protective eyewear should be worn by anyone operating equipment used in the installation
of SOSS Invisible Hinges, as should those in the area where the work is being performed.
Read these instructions prior to undertaking the installation of the SOSS Invisible Closer. These instructions pertain only
to the installation of the SOSS Invisible Closer. Instructions for the installation of standard (non self-closing) hinges are
enclosed in the package containing the hinges.
Please use at least one fire-rated closer for every 20” of door height or portion thereof , or one closer for each 55 lbs. of
door weight or fraction thereof, whichever calculation demands more closers.
Recommended Equipment
Hinge paper template (supplied) Spade or wood drill bits as follows:
Sharp Chisel for #216IC, 416IC, 416SSIC:
3
/4" bit for drilling spring clearance hole 1" bit for drilling hinge body mortises
Drill or Brace for #218IC, 418IC, 418SSIC: 1" bit for drilling spring clearance hole 1
1
/8" and
1
/2" bit for drilling hinge body mortises
Extension shaft for drill bits for #220IC, 220ASIC, 220SSIC: 1" bit for drilling spring clearance hole 1
3
/8" and
1
/2" bit for drilling hinge body mortises
8 At the punch point marked with B,
drill the required size hole according
to the following chart:
9 Using a chisel or router, remove the wood protruding into the
hinge outline to form a smooth mortised surface.
10 Locate the spring clearance starter hole, and remove any
excess wood preventing the drill from entering the starter hole.
11 Make sure that the proper size drill bit is being used for the
spring clearance hole!
The spring clearance hole must be drilled centered in the
starting hole, and must be drilled perpendicular to the edge
(thickness) of the door.
12 In drilling the spring clearance hole in hollow-core doors, you
will drill into the cavity of the door, thus completing the drilling
on the door side of the SOSS Invisible Closer. Solid-core doors
will require drilling the spring clearance hole 7" deeper than the
hinge-body mortise.
13 To create the hinge-body mortise for the jamb side of the
closer, repeat this sequence of instructions ignoring everything
pertaining to the drilling of the spring clearance hole. Ignore that
indicator on the template.
14 Once the hinges are installed and the door swing is found to be
satisfactory, the door closure speed may be set by adjusting
the socket-head fastener (requires
5
/32" hex wrench). Turning
the fastener in a clockwise direction increases spring tension
and door closing speed. The spring tension should be adjusted
gradually until the desired closing speed is achieved.
15 If all tension is removed, it can not be added once installed.
The hinge will have to be removed to add spring tension, then
reinstalled.
16 Lubrication may be used.
WARNING:
Self-closing doors are potentially dangerous to animals,
children and the handicapped! Suitable measures should be
taken to prevent anything from being caught between the
door and the jamb!
