HAGER
Companies - 139 Victor Street - St. Louis, MO 63104 (314-772-4400)
Part No.: 75009420
790-905
HAGER
Models 790-905 and 790-926 are Stainless Steel Continuous Edge Mount Hinges for 1-
3/4” (44.5mm) thick doors. They allow for
minor lateral adjustment to the door after installation. Both models feature protective corner guards. Model 790-
926 provides ‘swing
clear’ rotation. Clearance required between the hinge edge of the door and the frame rabbet is 9/32” (7.1mm) minimum. For metal
doors, a 1/8” (3.2mm) thick reinforcement plate is strongly recommended along the hinge edge for proper thread engagement of the
adjustment studs.
These models are
not
recommended for use on doors that have a beveled edge on the hinge side, nor for use on
doors that have electrical modifications such as through-wires (ETW) or power transfer devices (EPT).
Hinge Length
All
HAGER
Stainless Steel Continuous
Hinges are supplied 7/8” to 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.
Remove the bottom pin cap and trim from the bottom end of the hinge
only to achieve the desired length
– do not cut the top end. Undercut
the pin 7/8” shorter for clearance and reinsert the bottom pin cap.
Total Clearance Between Door and Frame Width
General Fitting Procedure
For new construction with metal doors/frames:
To accommodate the 9/32” (7.1mm) hinge clearance required for
HAGER
Models 790-
905 and 790-926 order the door undersized or the frame header oversized. See the clearance information above to attain the
proper finished width required. A 1/8” (3.2mm) thick reinforcement plate is strongly recommended along the hinge edge for proper
thread engagement of the adjustment studs. The hinge edge of the door should not be beveled. 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. A minimum clearance of 9/32” (7.1mm) is required between the hinge edge of the door and the frame rabbet.
Do not bevel the hinge edge of the door. See the clearance information above to attain the proper finished width of the door.
