Class 20(2) [Also in Groups XXII and XXV] A structural member comprises, in crosssection, two C-shaped parts 3 having inwardly turned flanges 9 on one face of a web 48. As shows there are two parallel webs 48 which are joined by flanges 18 extended on each side to form in co-operation with central flanges 19 four C-section parts 3. The flanges 19 may be joined by a bridge 19a. Two such structural members are joined at right angles by a bolt 6 the head 13 of which seats on a washer 7 engaging in the ends of slots 11 in the webs of one member, the bolt passing between the webs to engage a nut 5 which has been engaged under flanges 9 of the second member.
