Assemble Rail
Place Rail pieces (1) on a flat surface for assembly. Take special note of the raised
line on the Rail pieces (4) these lines MUST line up in order for the Rail to fit
together properly. All four Rail sections are interchangeable. Slide Rail Braces (2)
into slots on the sides of Rail. Make sure small tabs on Rail Braces (3) are up
against top lip of Rail. Connect Rail by sliding other end of braces into next Rail. Be
sure the raised lines that run down Rail sections (4) line up. Tap Rail assembly (5) on
a piece of wood (6) until Rail sections are flush. Repeat for final Rail section.
Reinforcement of rail (GPD65)
Install C-rail clamp when clearance between rail and ceiling exceeds 60mm.
Install the C-rail clamp (1) with bolt (2) and nut (3) included at position shown.
(fig.5A)
Position C-rail clamp on the joint of the first and second rail section from the door
closed position and tighten screw.
Make sure the C-rail clamp is located exactly over the joint of both rail sections. The
clamp is for additional reinforcement of the rail and not required when
headroom clearance is less than 60mm.

shown). Slide pin (5) through holes in Cable Pulley Bracket and Cable Pulley. NOTE:
Trolley with Magnet (6) MUST be installed in the position shown.
7
Insert Chain/Cable into Rail
Slide Cable Pulley Bracket (1) into Rail assembly (3), be sure to insert Cable Pulley
Bracket as shown. Push Cable Pulley Bracket toward front of Rail and slide Inner
Trolley (2) into Rail assembly. Magnet (4) MUST be installed in position shown or
unit will not function properly.
8
Attach Trolley to Rail

(2) toward unit and into slots on top of unit.
Attach C-Bracket (3) on rail and secure with screws (4) as shown. Push Cable Pulley
Bracket forward making Chain tight on sprocket. Chain MUST engage teeth on Drive
Sprocket.
10
Attach Rail End Bracket
Turn Rail and Unit assembly over. Slide Cable Pulley Bracket (2) toward front end of
Rail (3). Be careful Chain does not come off Drive Sprocket on unit or become
twisted. Slide Carriage Bolt (5) into Rail End Bracket (1). Secure with Lock Nut (4)
and Washer (6). Tighten Nut until Chain does not droop below rail. Do NOT over

INSTALLATION SECTION

Wear protective goggles when working overhead to protect your eyes from injury.
Disengage all existing garage door locks to avoid damage to garage door. To avoid
serious personal injury from entanglement, remove all ropes connected to garage
door before installing opener.
11
Find Center of Garage
Mark center of door (1). Extend line onto ceiling (2).
12
Install the Header Bracket
NOTE: Refer to vertical center and horizontal lines created in step 11 for
proper placement of header bracket.
A. Wall Mount: Center the header bracket (1) on the vertical center line (2) with the
bottom edge of the header bracket on the horizontal line (4) (with the arrow
pointing toward the ceiling). Mark all of the header bracket holes (5). Drill 4,5 mm
(3/16") pilot holes and fasten the header bracket with wood screws (3).
B. Ceiling Mount: Extend vertical center line (2) onto the ceiling. Center the header
bracket (1) on the vertical mark no more than 150 mm (6") from the wall. Make
sure the arrow is pointing toward the opener. Mark all of the header bracket holes
(5). Drill 4,5 mm (3/16") pilot holes and fasten the header bracket with wood
screws (3). For concrete ceiling mount, use concrete anchors (6) provided.
Clearance between highest point of travel and Rail should not exceed 50mm
and can be zero when clearance between door and ceiling is only 30mm.
13
Attach Rail to Header Bracket
Position opener on garage floor below the header bracket. Use packing material to
protect the cover. Raise rail until holes in the header sleeve and holes in the header
bracket align. Join with clevis pin (1). Insert ring fastener (2) to secure.
NOTE: To enable the rail to clear sectional door springs, it may be necessary to lift
opener onto a temporary support. The opener must either be secured to a support
or held firmly in place by another person.
14
Hang Opener
Bend Hanging Brackets (1) so they are flat against ceiling. Measure distance from
Header Bracket to Ceiling Mounting Bracket Bolts. Mark length on ceiling starting at
the Header Wall, along this point is where the unit will be mounted. Lift door to full
open position, rest opener on door. Insert Square Head Screws (A) into Rail
assembly (B) approximately 120mm from end of Rail near motor unit. Slide Hanging
Brackets on to Square Head Screws and secure Brackets with Nuts (5). In this
process the Square Head Screws hook into slots on the sides of rail. (C)
For concrete ceilings, drill 8mm pilot holes into ceiling and insert Concrete Anchors
(2). Secure Hanging Brackets to ceiling with Lag Screws (3). For wood ceilings, drill
4mm pilot holes and secure with Lag Screws (3).
Optional: A second set of hanging brackets is recommended when door is very
heavy. The hanging brackets should be located in the first third to the center of the
rail from the front or at the location the garage door opener lifts the rail upwards the
most during the travel.
