The Mark 3 Chock is designed for large aircraft, e.g. Boing 747 or Airbuss A380, and aviation equipment. The product is made of very durable, lightweight polyurethane. The material is resistant to extreme weather conditions, oils, propellants, as well as a high tear and abrasion resistance. Thanks to the material properties, the block will never rot, crack or splint. Tests have shown that Mark 3 Chock takes more wheel force than conventional rubber blocks. The grille in combination with the slope of the block together with the wheel pressure generates a constant grip.
Mark 3 Chock has an innovative aluminium handle, which generates a lever and thus an increased user-friendliness. To increase the product's user-friendliness even further a rope runs through the aluminium handle. A reflex is placed on the outermost part of the handle in order to further visualize the block if it would be placed behind a wheel. Thanks to the shape of the block in combination with the handle, it is easy to place at the right place. The material is 100% recyclable.
