Made of solid brass, our Long Brass Radiator Wall Stay is 250mm long and perfectly compliments our deeper radiators i.e. those over 160mm deep. We also have shorter radiator wall stays available, at 165mm, in both galvanised steel and solid brass. The standard steel and brass wall stays are both   suitable for radiators under 160mm deep. We recommend one wall stay for up to 15 sections of radiator and two thereafter.
