This is the corner section of the Griffin Gaming Modular Paint Rack, it is used to extend the rack on the corner of your hobby area. Other sections can be added to this corner section. This section is made for storing large paint pots such as Citadel, Turbo Dork, Pro Acryl and others. This section will hold a total of 25 paints. If you have other sections of the Griffin Gaming Modular Paint Rack you can also re arrange these to suit your own needs and mix in dropper bottles, vertical supports and more. Elephant foot compensation needs to be set to .25mm The tolerances are very tight and you may need a little force to fit the sections together, do this carefully and from the end and not the middle of the section.
