The "Mark 6 Chock" is designed for large aircraft, e.g. Boing 737 or Airbuss A320, 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 6 Chock takes more wheel force than conventional rubber blocks. Mark 6 Chock has an innovative aluminium handle, which generates a lever and thus an increased user-friendliness. 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.
