Effective Clear Width

Please enter the door width size for the required clear effective opening and follow the below steps.

1) Enter the overall tolerance for your doorset (i.e., a fire rated single door would have a gap of 3mm between the door & frame each side, so 6mm overall all).

2) Enter the door thickness

3) Enter the stop/ rebate size on the frame (i.e., if you’ve got a 32mm x 12mm stop, enter 12).

4) Enter the hinge knuckle size required.  Please note:  All hinges used on our doorsets have a 14mm knuckle.

5) Enter the handle projection size from the face of the door.  Please note:  If the door opens past 90 degrees or the door is for a dwelling, then handle size is not relevant.
