BFT PHOBOS N BT Installation Manual

Table 2.1
IDEAL GEOMETRY - A symmetrical geometry will give you even speed and torque throughout
the entire movement of the gate as well as equally strong leverage to hold the gate in position
at both open and close ends of strokes. If you are welding the post bracket, when possible, use
the geometry in table 1:
Table 1
USING THE ARB BRACKETS - The ARB adjustable brackets simplify the installation process.
The tables 2.1 and 2.2 gives you different options depending on the three most common gate
hinge offsets. These dimensions only apply to installations where the fully closed gate is square
with the gate post. DO NOT DEVIATE FROM THE DIMENSIONS ON THE TABLES
