ClosetMaid designed this bracket exclusively for the ShelfTrack hang track and bracket system, which allows wire shelves to be adjusted to any height. The system creates a versatile storage solution, great for both your large and small spaces. Durable metal construction and double-slotted design provide strength and durability. Standard brackets need to be placed no more than 24 in. apart and 4 in. from the end of a shelf for the utmost stability.
