the dumbell rack be very easy to assemble use a rachet wrench & a cresent wrench . it be very sturdy and of very good quality . I recommend this rack if you only use dumbell set up to maybe about 50 lb . there be not enough room for heavier set of dumbell . I will soon buy a second rack for my 60-100 lb . dumbell and it will be the same Apex Deluxe Rack that I be describe here . sincerely , E. Flynt of Cleveland , Ohio
