SPECIAL MEASUREMENTS INWARD OPENING (Fig.2)
EXAMPLE (STANDARD)
EXAMPLE (SPECIAL DIMENSIONS)
*measurements in mm.
In some cases it may be necessary to vary the standard dimensions, e.g., because of space restrictions in fixing the supports. The above
graphs show dimension ranges for inward opening 360 and 240 models.
At the top part of each graph are the range of gate opening angles and a series of diagonal lines from which the values of A and B may
be determined (fig.2 page 5 ). These values should be as near as possible to those determined by the thick vertical line.
The dimension for C is constant at C = 90 mm for model 360 and C = 70 mm for model 240.
Example: What should be the value for A and what model should be used for a gate with an opening angle of 100º where B = 140?
Answer: Model 360 where A =195 mm. See the example in the above graph shown by the dotted line for the 360 model : EXAMPLE
(SPECIAL DIMENSIONS))
Conclusion: It would not be possible to use the 240 model because the value for A would be outside the minimum for this model.
