Adjustable Deck Railing Planter Box Bracket is a 4 pack metal hanger set that holds flower boxes and planters on balcony deck and fence railings without using any floor space. The bottom tray slides on a slotted track and locks with bolts so it fits a wide range of planter box widths while the front lip angles upward to keep the box from sliding off. The top hook mounts two ways. Standard mounting suits thinner railing sections and reversed mounting suits thicker ones so one bracket set covers most deck balcony and fence railings. Two included accessories let you fine tune the fit. A bottom support bolt levels the planter and a rear locking plate holds the bracket tight against the railing to prevent forward leaning. Made of black finished metal. Weighs 3.97 lb. Sold as a set of 4 brackets color Black.
