Locking Tabs For Corner Boxes

Locking tabs are an optional addition to corner box walls. They are intended to help hold walls aligned when two or more corner boxes are combined into one room. They work with both corner boxes and middle extension sections.
   
Recommended Assembly Procedure
1) Begin by gluing two tabs to the backside of one wall. White (Elmer's) or wood glue is recommended. The tabs should point downward. The engraved line should line up with the edge of the wall.
  
2) Position the second wall next to the first wall, as they will fit together when assembled.
   
3) Glue tabs to the second wall, mating them with the tabs on the first wall. Be careful not to get glue on the area touching the first wall.
   
4) Allow the glue to fully dry before assembling the corner boxes.
