Claim 25:
26. A hinged safety gate comprising:
a gate frame configured to control access to an elevated work surface access area, the gate frame having a frame adjustment region, a distal upright member, an upper cross-arm, and a lower cross-arm, the upper cross-arm including an upper main tube and an upper extension tube, the lower cross-arm including a lower main tube and a lower extension tube,
wherein the lower main tube comprises a tab that extends an axial length beyond a distal end of the lower main tube and that comprises a partial tube,
wherein the lower cross-arm further includes a lower ring clamp configured to hold the lower main tube and the lower extension tube together, the lower ring clamp having a lower ring clamp body with an axial length approximately equal to the axial length of the tab the lower ring clamp body comprising an inner profile with a tab portion that matches and mates with the tab and with a lower extension tube portion that matches and mates with the lower extension tube, the lower ring clamp further comprising a fastener configured to push the tab into clamping contact with the lower extension tube and to pull the lower ring clamp body toward the lower extension tube, thereby pulling the lower extension tube into clamping contact with the tab; and

a retainer assembly configured to be attached to a proximal end of the gate frame and configured to hingedly couple the gate frame to a first stationary vertical surface to permit the gate frame to swing between an open position and a closed position in which the distal upright member is positioned proximate to a second stationary vertical surface, the second stationary vertical surface opposing the first stationary vertical surface;
wherein, when the lower extension tube is not in clamping contact with the tab, the gate frame is movable between an extended position and an unextended position with the lower extension tube being telescopingly slideable within the lower main tube and the upper extension tube being telescopingly slideable within the upper main tube.
