1:76 CANAL LOCK SET

 Canal lock set comprising  4 brick wall sections, 2 pairs of gates, 2 pairs of gate recesses, 2 steps and 10 narrow brick pathways.

Dimensions. 440 mm L overall x 5 mm thick walls x 24 mm H. Internal Length of lock from 1 set of gate hinges to the next set is 280 mm. The walls can be set apart  to create locks ranging from 47mm 73mm wide.  

The 'in action' photos show it on my own layout set up to accommodate a single narrow boat. You can make it wider by altering the gate closing angle to take 2 boats side by side.  The photos are just to give you one possible use for the set. Multiple sets could be added together to create a flight of locks.
