Block Concrete 58″ smooth top (Set of 30) HO N Z

These concrete blocks are 24 in. x 24 in. x 58 in. They are used to build retaining walls or set out individually as vehicle barriers. This model is designed without the top detail to make it easy for the model builder to stack and create custom retaining walls. Use the 58in. block with top detail (sold separately) to finish off the top row of your block retaining wall.  Retaining walls built with these blocks can be seen on tunnel 3 in Tehachapi, tunnel 5.5 near Greenfield Calif.  and the San Fernando tunnel in the Newhall Pass. 3D printed in grey polymer resin for high resolution finish. Comes with supports attached. If your scale is not listed please inquire about a special run.
