Accessories for training apple trees

[thomasb]

I am interested in getting some apple trees and train them as 45-degree cordons up the side of a fence.
Where can I get the accessories I require? I am after the 'eyebolt strainer', wire and other items for putting up the propper wire supports needed for the trees.
Any help would be great.

I have discovered that B&Q sell the bolts much cheaper than garden centres.  I have discovered that for me the screw in eyelets work as well.  Wilkinsons are usually good for wire, but this is the wrong time of year - B&Q or garden centre.
