Restricted side room installation
Where there is restricted side room (between 515mm &
350mm) the secondary arm must be cut to suit.
Move the primary arm into a position suitable for the gate in
the closed position. Measure as in Fig C while temporarily
clamping the bracket to the gate.

Move the gate to the open position as in Fig D, and re-
measure. The correct bracket position and secondary arm
length will be when the distance is equal for the open and
closed.
Caution
Ensure that the secondary arm dose not interfere with
the primary arm.
Minimum angle between the primary & secondary arms,
in the open position should be no less than 40degrees.
