Retractable Garage Door Gear

STEP 1: FRAME DETAILS

Minimum frame size 70mm x 70mm. Frame must be square, check diagonals. Frame must also be square with brick opening.

STEP 2: FITTING ROLLER BRACKETS & WEATHER STRIPS

GO STRAIGHT TO STEP THREE IF TOP ROLLER BRACKETS AND WEATHER STRIPS ARE PRE-FITTED.

Locate the top roller bracket flush with the top of the door matching the same overhang as the top weather strip. On doors OVER 50mm (2") thick; lower the top roller bracket by the same amount. ie door thickness 62.5mm (2 ½") lower the bracket by 12.5mm (½"). Fix the roller bracket and weather strip using No. 12 x ¾" self tapping screws.

TAKE GREAT CARE NOT TO DRILL RIGHT THROUGH THE DOOR FACE.

STEP 3: POSITION DOOR IN OPENING

Wedge the door in to the opening allow 10mm side clearance, 10mm clearance between the top of the door and the header and allow at least 10mm ground clearance. 

STEP 4: INSTALL THE TRACKS

Locate the track over roller, support rear of the track allowing between 25mm and 40mm fall to the rear.

With the track JUST TOUCHING the bottom of the roller drill 2 x 6mm pilot holes in the middle of the slots in the track brackets. Fix 2 x M8 x 60 coachscrews.

Slide on track support bracket and fasten to a suitable support using 1 x M8 x 40mm coachscrews and washer ensuring track is square to door and allowing fall as above. Fit rubber buffer by drilling 9mm hole in track and secure with M8 x 30mm bolt / nut / washer as fitted. Position rubber buffer towards rear of track but not so far as to allow door arm to hit spring anchor bolt. Door must stop against rubber buffer not arm against anchor bolt.

STEP 5: INSTALLATION OF ACTIVATING ARMS 

Locate the bottom weather strip allowing 3mm (1/8") gap, fix using No. 12 x ¾" self-tapping screws. Identify the two activating arm bracket holes in the weather strip (outer holes). Drill two 10mm holes through the frame to accept the M10 X 90mm COACHBOLTS. Feed coachbolts from the outside and securely fasten the activating arm. On doors with bottom slotted plate - locate door bracket and mark fixing position in the MIDDLE of the slots, drill 2 x 5mm PILOT holes and fix using M8 X 40MM coachscrews and strengthening plate.

TAKE CARE NOT TO DRILL RIGHT THROUGH THE GARAGE DOOR.

IMPORTANT. For proper operation the frame must be square. If the frame is out of square the bottom weather strip MUST be square to the door. Otherwise the door will not operate correctly.

STEP 6: INSTALLATION OF SPRINGS

Open the door and prop it firmly in the fully open position. The top spring anchor is fitted as shown. (REFER TO STEP 8 IF RE-ADJUSTMENT IS REQUIRED FOR A GOOD BALANCE).

Locate spring over top spring anchor pin, hook spring anchor bolt over bottom of spring anchor pin, hook spring anchor bolt over bottom of spring, locate bottom spring anchor bracket through spring bolt by about 25mm. Locate suitable fixing position and through one hole drill 10mm hole to accept M10 X 90mm coachbolt and drill 6mm pilot hole in the other fixing for M10 x 60MM COACHSCREW. Tighten spring about 25mm each side at this stage.

STEP 7: INSTALLATION OF TRACK SUPPORTS

Remove the prop and if the arms are not in the vertical position, re-adjust the rubber buffer bracket the SAME at each side. If the door is online touching one buffer the tracks are NOT square. From behind the door if the left hand buffer is not touching the roller move BOTH tracks to the Right. When rollers are touching both buffers and activating arms are both at the same position the tracks are square. Now secure the track hangers and stabilisers. Finally recheck all is square.

STEP 8: DOOR ADJUSTMENT

The door should be working in a satisfactory manner. However, after installation the door can slightly check:

Is the gap between the top and the bottom weather strips still 3mm (1/8") if not, SLIGHTLY loosen the coachscrews/ nuts in the bottom activating arm bracket and raise the door to achieve gap, then re-tighten coachscrews/nuts.

Are the top rollers just touching the bottom of the tracks? If not adjust front track brackets and re-tighten.

Is the door clear of the frame during opening and closing? If not check first that the tracks are square, see STEP 7. If door still catches frame, adjustment can be obtained by adjusting door brackets, loosen coachscrews/ nuts SLIGHTLY adjust then re-tighten screws / nuts.

In order to prevent the top weather strip damaging soft timber frames, a pair of running strips are included. These should be fitted as shown with the centre of the rubbing strip placed over the top weather strip contact point (this contact point will be different on a manual door to one fitted with an electronic opener).

NOTE: Adjustments will NOT overcome incorrect fitting. Great care should be taken to ensure that your door frame is square and the door is square. Also that the activation arms are vertical and true to each other.
