Product specifications

The Lattix® 4438 mast system can be used as mast for sign support, other information and surveillance equipment or other applications. The mast is delivered as a complete assembly including mast, base plate and top plate.

The mast is tested and approved according to:

Full-scale impact crash tests and simulations have been performed according to EN 12767 at a speed of 35 km/h and 100 km/h with 6,3 m mast length. Simulations show that the mast will have equal performance up to 8,623 m length. Consequently, the mast is approved for maximal 8,623 m and minimal 1,8 m from the ground to bottom of sign.
