This study analyzed the effects of L-profiled corner joint design on maximum load-carrying capacity of case furniture. For massive panels material (Red Pine), two test groups were formed using Polyvinyl Acetate (PVAc), Desmodur-VTKA (Polymarine) and Purocal (polyurethane-based) adhesive types. First group test samples were prepared using L-profiled corner joint and second group test samples were prepared without using these. Both test samples were prepared using dowel joints. Maximum load-carrying capacity values obtained after diagonal compression and tension tests on test samples were analyzed. The evaluations indicated that the load carrying capacity of the test samples prepared by using L-profiled corner joints was four times greater than that of other group.
