These dimensions are taken from actual products (rather than manufacturer's spec sheets) but individual items may slightly vary from this - it's impossible to check & verify every product before it goes out. These figures are therefore not guaranteed 100% accurate - if you have a specific requirement on sizes, please contact us before ordering.
