D-marc™ 105

Demarcation system which can withstand wind speeds of up to 105 mph due to the unique design of its base and upright which also eliminates any potential damage caused by oscillating. Its three connecting pins do not protrude through the base and therefore do not come into contact with the roof structure, ensuring it cannot damage the roof even if it begins to oscillate. It has a non-protruding integral hook incorporated inside the lattice structure which ensures the chain cannot lift off the upright in high winds.

Feature and benefits:

• Withstand wind speeds of up to 105 mph.
• Trapezoid base shape is aerodynamically designed with four pyramidal sloped sides at 30°, which, in extensive wind tunnel testing was shown to be the most stable shape.
• The underside of the base is sculpted ensuring the weight is distributed to its perimeter, minimising the effect of wind uplift.
• The lattice structure of the upright ensures the wind circulates around and through the system rather than pushing it over.
• D-marc™ 105 is classed as a form of Collective Protection in accordance with the HSE’s hierarchy of risk management as set out within the Working at Height Regulations 2005 (WAHR).
• Minimum distance from fall hazard: 2 m.

Components:
