Determine the Position of the Post Bracket
1. Measure the Value C.
2. Value D will depend on the position where the post bracket is mounted.
3. Value A is the total length for both C and D.
4. Value B will depend on Value A and the maximum opening angle of the gate. Refer to
Table 1 below.
NOTE: For optimal mechanical advantage Value B must be close or equal to Value A.
5. Determine the A and B measurements provided in Table 1 to confi rm the position where the post
bracket will be mounted.
