Is old Montgomery (KONE) elevator Mac door equipment still available for sale ? Does GAL have conversions for these tracks ?

You can get boards, but not the equipment per say. Converting to GAL is fairly simple

Yes, KONE Spares sells MAC door operators and equipment.

They only have spare parts now. The best conversion pkg is the Wittur SGV or AMD. You will need to replace tracks on the cab side, but not the hall side. The nice thing about this product is that it's spare parts are available from Wittur, KONE and TKE (Vertical Express). You could also try Columbia Elevator. They sell knock off versions of the MAC. It's possible they may have stopped though.

Thanks everyone
