Do I need to glue the joints when assembling these Full Access Cabinets?

Yes and No, depending on if you choose to use Integral Finished Ends or Applied Finished Ends. If you choose to use Integral Finished Ends, you will need to use a PUR glue (i.e., Gorilla or Titebond PUR) in each female Lamello clip. PUR glue is the best choice, and the glue joints it produces far exceed all KCMA specifications.

Your objective is to glue the fastener (I like to glue the vertical part, letting glue run down into the female Lamello fastener), so that once the glue dries, the glue fills all the space behind the tines, keeping the fastener from being able to come back apart.

If you want to run a small bead the entire length of the joint for good measure, keep the bead as thin and tight as you can as PUR glues foam, and tend to ooze out if you use too much.

If you choose to use Applied Finished Ends, the you will find all of your unfinished ends will have 3mm pilot holes so you can screw your cabinets together. If you choose this route, you do not need to glue your cabinets together. Even if you do choose to use Integral Finished Ends, you can skip gluing all of your unfinished ends as you can screw them together.
