Tried most Gridfinity Multiboard shelves and was unhappy. Either poor fitting, too much material required or lack of magnet support. Found the Gridfinity Refined models perfect and decided to remix them with pegboard clicks, so no bolts or snaps are required to secure the shelf to the Multiboard.
The author remixed this model.
Fitted the excellent Gridfinity Refined grid with pegboard clicks to ensure safe fitting on Multiboard pegboard
