R7s Lamp Holder K523 For Big Rad and similar heaters that use push-fit high temperature connections.
This pair of lamp holders are replacements to the lamp holders fitted to the Big Rad Heater by Prem-I-Air.
These sometimes burn out when there is a bad connection between the lamp and the holder.
They are relatively easy to replace but the old holders may be riveted so you need to drill the rivets out of the old holders before replacing with these spare parts.
