This invention relates to the construction of
towers, masts and analogous structures.
The principal object of the present invention
is the provision of improvements whereby struc
tural elements may be rigidly secured to each

to effect the rigid securement of the structural
elements aforesaid.
The securing device referred to consists of two
main parts. One of said parts consists of a cross
bar l2 having a clamping member 13 ?xed on
one end thereof in any suitable manner. The
other in extended relation regardless of any in
member

equalities in the cross-sectional sizes of such ele
