STEP 3
1. Cut out two square silica gel plugs as shown in the figure
2. Insert the left and right handrails into the corresponding positions respectively,
and put 2 M8*50 semicircle head hexagonal socket screws through the column pipe
respectively, and lock the 5mm hexagonal socket wrench inside the screw package
into the corresponding screw hole, and then put the square silicone plug back into
the front hole.
(Note: If it is difficult for the half-round head screw and the hexagonal socket screw
to pass through, you can use the 6mm hexagonal socket wrench in the part package
to pass through the column pipe to connect the handrail for positioning, and then
insert the half-round head screw and the hexagonal socket screw.)
