These are manufactured by hand with either 25mm aluminium or wood slatting in 25mm or 50mm. The slats tilt open from flat level and close downwards only, with the slats drawing up to where the headrail starts when possible. The headrail is aluminium and we colour co-ordinate this as far as possible with the slat colour, or if the customer requests, contrasting with the same options on cord and ladderstring.
