Ikea Lack table joiner/stabilizer

Dimensions are 61mm x 61mm x 60mm (L x W x H) with 51mm x 51mm internal clearance for the legs of the upper table. The holes are designed for #8 construction/wood screws, though the brackets fit so snug on my setup I chose not to use them. I wanted a more secure and tightly fitting stacking/joining bracket for two IKEA lack tables. There are similar designs out there, but few that did not involve rising the table or they neglected mounting with hardware. I personally have also added rigidity to the tables using the below user's model. Arministrator82 - Ikea Lack table stiffener Please keep in mind the weight limits of the original product.
