These brackets are welded steel to provide a very strong and sturdy wall mounted system. Typical installations use a four foot spacing for schools and studios and up to eight foot for ballet use where the barres will not be abused. When using your own wood please remember we use hardwood ash and if a softer or smaller barre is used the spacing should be adjusted accordingly.(click on picture to enlarge) Single Wall Bracket Regular price: $26.00 Sale price: $24.00 Double Wall Bracket Regular price: $30.00 Sale price: $28.00
