Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.

Don't hesitate - Great product!
Size: 12 Inch, Color: Black
Superior quality at an unbelievable savings over local retailers. Hardware for hanging included the cheaper plastic lags yet they also included the heavy duty lags, so no tapping in to our supply. Thank you for a great product
