Galvanized steel Brackets are used to clamp Studrail onto intermediate posts.
To calculate the number of brackets you require either divide the number of metres
of Studrail by your post centres,
eg. 500 metres of Studrail / 2.4m post centres = 208 brackets, or multiply
the number of posts you have by the number of rails you require.
eg. 120 posts x 2 rails = 240 brackets.
