Below you can see a new re-enamelled pre-74 Aga range cooker'Deluxe' 4 oven 'one piece' hob and lids. The hob is the single flat section that fits around the hotplates and flue. It must be lifted in above the hotplate and dropped down onto the front, back and sides of the Aga range cooker on which it sits. It is secured onto 'tie' rods that go right down to the bottom of the cooker by hob screws. The hob caps screw into these to finish the look. The hinge blocks are always re-enamelled along with the towel rail brackets and towel rail itself if it's looking shabby!
