Abstract
Sliding extensible support that is formed by two u-section profiles reciprocally adapted in telescopic form that in their free ends have between their wings two sets of slide sliding bodies, counting, the outer profile, with its longitudinal edges doubly deflected inwards to form two guide and retention rails to effectively stabilize the interior profile.
