NOTE 1 : IT IS NOT POSSIBLE TO COMPLETE THE ORDER WITHOUT SELECTING THE RAIL LENGTH. AN EXTRA PRICE IS APPLIED TO RAILS 220 CM AND ABOVE. FOR THOSE WHO DON'T KNOW HOW TO SELECT THE RAIL LENGTH; THERE MUST BE A SPACE AS MUCH AS THE WIDTH OF THE DOOR WHERE THE DOOR WILL OPEN. FOR EXAMPLE, IF YOUR DOOR IS 80 CM, 160 CM RAIL WILL BE ENOUGH; IF YOUR DOOR IS 85 CM, 180 CM RAIL WILL BE ENOUGH. NOTE 2 : You should consider the following when purchasing slow-down stoppers: To give an example for a single door mechanism, when 1 piece is selected, you can complete your order depending on which direction of your door you want to use the slow-down system - either while opening or closing - when 2 pieces are selected, you can create your order depending on whether you want to use it in both directions of your door - both for opening and closing.
