The idea is simple, an adjustable buzzer bar, with removable fittings, for maximum flexibility and ease of use. Each pair of bars is manufactured from high-grade 316 stainless steel and are supplied with 4 thread caps, which enable you to protect the threads whilst not in use. Also available in black anodised aluminium. The switch between bars and single sticks has never been simpler, the fixings are FULLY-adjustable, removable and also enable you to use this system as a T-Bar or Goal-Post arrangement, front and back.
