To make the A frame use the 130mm bolt, nut and washer, and push through both part A's. The nut
and the washer will sit in the recess around the bolt hole. Then spread the legs out so the
measurement from outside to outside of the part A's is 255cm. Then drill two holes at each end of
part C approx 30mm in. Fix using 4 x 60mm screws. This rail should be flush with both sides of parts
A and the same distance up from the bottom of Part A.
