Two elongated tubes (11) (13) have respective diameters such that one tube (13) can nest inside the other tube (11). The two tubes (11) (13) are long enough that when the inner tube (13) is extended from its nested position, the overall length of the two tubes (11) (13) is in a range suitable for supporting or spreading tree branches. The interior surface (26) of the outer tube (11) has thereon a first plurality of raised portions which mate with a second plurality of raised portions on the exterior surface (28) of the inner tube (13) such that when the two tubes (11) (13) are in one rotational relationship, relative longitudinal movement of the two tubes (11) (13) is permitted, while when the two tubes (11) (13) are in another rotational relationship, relative longitudinal movement of the two tubes (11) (13) which would tend to shorten the prop is prevented.
