There is a choice of cills (A-J). Specials can be made to suit structural requirements, wheel chair access etc.

These are fitted at no extra cost if specified at the time of order.

This type of cill is used when perhaps the floor outside is raised. Using this cill will allow the door to swing freely open without being obstructed by the outside floor.

This cill is only ever used on an inward opening door. The cill is fitted in the rebate of the frame, with the slope running down towards the outside. Thus if any rain runs down the door onto the cill it will then run down the slope of the cill and onto the outside floor.

Type C cill is commonly used on doors where perhaps wheelchairs, trolleys, etc. are common traffic through the doors.

Type D cill is used in the same situations as type C cill.

This is a 6mm flat bar cill which fits directly under the frame. This cill is particularly good when the floor isn't finished or is uneven or crumbly etc. Please note that this is not a standard cill and is chargeable.

This cill fits at the back of the frame. A good cill to choose if a flat low level cill is required, also if a panic bolt is being used on the door.

Type G is an aluminium latchtrack cill. This is not a standard cill and is therefore chargeable.

The most popular cill is the H type. It is similar to type F but it has a leading face which fits under the door. Good for every kind of purpose, particularly panic bolts.

Another cill with a sloping face, again used for the purpose of trolleys and wheelchairs etc. This has a deeper back of 25mm compared to cills C and D.
