You can tell these are solid as can be! They aren't hollow molded they are solid! You can feel the quality when you pick it up. Other reviews commented that they did not send you the mounting hardware mine came with everything needed! You can't go wrong with this product.Look below for the package contents. Only thing I would be weary of using is the included carabiners my porch swing at times has at times 600 Lbs on it that's why I needed something heavy duty.Package contents:4- Washers4- 4 Hex Head Lag screws 3/8 x 3”2- Heavy Duty swing brackets2- CarabinersWill update the review, after prolonged use.Installation update: I have these now installed on my porch swing new picture included. The nylon bushing's are super quiet! We have tested the swing with around 615Lbs sitting on it and it has held up well! Make sure when installing to pre-drill all 4 of your holes with w 5/16 drill bit. This is for ease of installation and to prevent any cracking or splitting of the beam you are drilling in to.
