If satisfied with the rack level fasten the first "TEK" screw (supplied) in the middle of the slot
nearest the closing edge of the gate.
Move the gate towards the open position. Far enough that you can access the last mounting slot
at the opposite end of the length of rack to the end already fastened. Fasten the next "TEK"
screw here while the rack still rests atop the pinion.
To install additional lengths of rack, move gate closed until the next length of rack meets the first
length and the opposite end once again rests on the pinion. To ensure the 2 lengths of rack
marry correctly use an off cut of rack clamped upside down across the join of the 2 lengths.
Continue to fasten the "TEK" screws as before.
When finished installing sufficient rack to allow for the full travel of the gate plus enough to allow
for the limit actuator (as shown in the next section) remove the spacer plates and test the
meshing of the rack and pinion. (See above pictures of rack spacing). If satisfied fasten a "TEK"
screw directly through both the rack angle and the gate so that you have 5 "TEK" screws per
length of rack evenly spaced.
