The thread does not match that of my cat tree, so the product is unusable! The product description is insufficient from the site! In addition, the screws being tightened screws which themselves simply by screwing the screw head is a star shape and a bit special, but there is no key to maintain and improve the tightening ! This is a package that will stay on my hands because I do not have a printer for the label and do not want to pay the return shipping cost!
