ABSTRACT:
A lock for a tubular telescoping support such as tripod leg includes a clamping lever for locking inner and outer members against telescoping displacement and load bearing portions interposed between the two members such that the locking force applied by the clamp is circumferentially distributed among the clamp and two load bearing portions to thereby prevent flattening of the inner tube under locking clamp force.
