ROTON Model 780-211HD is an Aluminum Continuous Geared Half Surface Hinge that provides a 1/16" door inset. It can be used with any frame or frameless wall without hinge preps, and either with or without reinforcements depending on door weight. The frame rabbet must have a flat surface at least 1-15/16" wide and the frame face must have a flat surface of 1-17/32". Minimum clearance between the hinge edge of the door and the frame is 5/32" (4mm). "HD" models have additional bearings for heavy-duty application.

Hinge Length:

All ROTON Hinges are supplied approximately 1" shorter than the nominal door height to avoid threshold or carpet clearance problems. If the hinge must be trimmed shorter, first determine the correct hand of the door and orientation of the hinge. Then mark and trim from the bottom of the hinge only - do not cut from the top end.

General Fitting Procedure:

• For new construction with metal doors/frames: To accommodate the proper clearance between the door and frame, order the door undersized or the frame header oversized. See the clearance information above to attain the proper size. A minimum clearance of 5/32" (4.0mm) is required between the hinge edge of the door and the frame rabbet. Mortar guards, either Styrofoam or wood, are recommended for frames to prevent grout from interfering with the installation of the hinge fasteners.
• For new site-hung wood doors: If necessary, scribe and cut from the latch edge of the door to leave sufficient hinge stile thickness for proper fastening. See the clearance information above to attain the proper finished width of the door. A minimum clearance of 5/32" (4.0mm) is required between the hinge edge of the door and the frame rabbet.
• For remodeling with existing wood or laminate doors: If necessary, scribe and cut from the hinge edge of the door and plane smooth. See the clearance information above to attain the proper finished width of the door. A minimum clearance of 5/32" (4.0mm) is required between the hinge edge of the door and the frame.

Installation Procedure:

Frame Preparation (See Fig.1)

1. With the hinge open, place the hinge frame leaf against the frame rabbet making certain that both faces of the hinge are flush against the frame face along its entire length. Position the top of the hinge 1/16" (1/8" maximum) below the header. Note: A 1/16" shim is recommended due to initial settling of the bearings.

2. Rotate the door hinge leaf out of the way, to make it accessible to mark and center punch the screw hole locations. Accurate location is important for proper installation.

3. For metal frames 12 gage or less, it is not necessary to pre-drill pilot holes if using the self-drilling screws provided. For metal frames larger than 12 gage, drill and tap all mounting holes for #12-24 threads prior to installing the screws. For wood frames, pre-drill pilot holes using a #18 bit for optional #12 wood screws.

4. Attach the hinge to the frame. For metal frames, use the #12 self-drilling screws provided (recommended driver speed 1,900-2,500 RPM). For wood frames, use optional #12 wood screws.

Door Preparation:

1. Rotate the hinge leaf out of the way and set the door into the frame, using shims or wedges to adjust for the desired clearance on all sides.

2. Allow an additional 1/32" of clearance on the latch edge of the door at the top only. This will allow for any settling or twisting of the frame that may occur after the shims are removed and the weight of the door is transferred entirely to the frame.

3. Allow 1/16" clearance between the top of the door and the frame header rabbet. A good method for this is to use a 1/16" thick shim placed over the top edge of the door.

4. With the door held securely in place, rotate the hinge leaf into position on the face of the door.

5. (Standard sexbolt mounting) - Mark and center punch the locations of the larger 3/8" diameter holes. Accurate location is important for proper installation. Rotate the hinge leaf back out of the way. At each mark, drill a hole completely through the door using a 3/8" (9.5mm) bit. (Optional mounting without sexbolts) - Mark and center punch the location of the smaller 15/64" diameter holes. For metal doors, use optional #12 self-drilling screws. For wood doors, pre-drill pilot holes using a #18 (.170"/4.5mm) bit for optional #12 wood screws.
