Guard rail clamp with adjustment by wedge
as fall arrester when working at a height. The clamp is pressed to the ceiling by the
wedge and can be used on ceilings up to 40 cm thickness. The wedge produces the
required pressure and is fixed to the clamp by a chain so that it is captive. For arresting
fall, planks can be installed in the 3 hooks provided. The planks can be fixed in
holes in the hooks, in which nails can be driven to fix the planks.
