Abstract: A telescopic counterbalance for a hinged closure includes inner and outer telescopic members which are biased apart to their telescopic outward position. Bearing arrangements on the inner end of each member slidably bear on the other member. The members are located in extended position by a plurality of depressions on the outer member engaged by an integral collapsed rib on the inner member. The depressions and rib are located intermediate the bearing arrangements and the ends of the member to space the bearing arrangements and increase the bending strength of the counterbalance.
