摘要
The arms (2) of the safety grid are mounted on the frame quadrants (1) and are drilled for these rods (1) and also for the grid bars (3), and with U-washers (5) set between arm (2) and bar (3). The longer bolt guide (8) has a milled slot for the bolt movement and has the closing component screwed into it so the bolt can be moved through this slot to lock and release the grid. The bars (3) have a hinge bar (1) at their top ends and the top end of the telescopic rod (12) is anchored rotatably in an end profile (13) which in turn can be pressed in correct position against the top jamb of the frame by a clamp. Component (15) is hooked into the center bar and is held by the bolt to increase general stability.
