9.3 Physical Installation - Inward Opening
9.3.1. Step 1: Determine the Gate Bracket Length (E-Value)
It is essential to first determine whether the correct Gate Bracket length (E-Value) can be
achieved according to Table 9 (Installation Table) as described below.

Example for a 90° Inward Opening Installation
Measure the hinge depth from the centre of the hinge point to the face of the gate.
If the hinge depth is greater than 30mm, then refer to Section 6.6.
For this example, a measurement of 25mm will be used.
E-Value = D-Value MINUS Hinge Depth.
Thus: E-Value = 110mm – 25mm = 85mm.
If the E-value is greater than 85mm, you may choose any installation position shown in
Table 6.
If the E-Value is less than 80mm (for 90° inward opening) or less than 77.5mm
(for 100° inward opening), the operator WILL foul against the gate during operation as
shown in Figure 9. In order to rectify this, refer to Section 6.6.
