Standard Threshold with Deep Bottom Rail (No Cill)

All of the above have the option of putting a cill underneath. This would add another 25mm to the threshold height. The cill is available in various widths with 150mm being the most popular choice.

If you require a trickle vent then a 42mm add-on is placed on top of the head profile. This provides adequate space for any plasterline.
