Abstract
A tripod and a method of stabilizing a collapsible stand are provided. The tripod includes three legs attached to a base that swing open to a predetermined angle against a positive stop. The legs are locked into place in the open position via a leg spreader that forces (or pre-stresses/pre-loads) the legs outward against the stops. The method includes the steps of pivoting the legs of the collapsible stand to an open pivotal position into engagement with a stop, applying a load upon the legs to force the legs against the stop, and maintaining the load upon the legs while the stand is in use.
