Crank Handles

No Control Drop

If you don’t specify the size of the crank handle, it will be made to the size of the blind drop minus 230mm.

image

Control Drop

If you provide a control drop, this will dictate the total length of the crank handle itself.

image

Separate Crank Handle

When a separate crank handle is ordered the total height will be exactly equal to the length specified in the order.

Deductions

Deductions dictate how much you need to take off your recess size* to get to the blind size* of any given product.

Recess Size: The side-to-side and top-to-bottom measurements of the reveal the blind is going in.

Blind Size: The finished size of the blind you’re installing.

‣

Orientation

This dictates which way the headbox of your blind points when installed.

Standard Orientation

image

Headbox protrudes outwards, putting the fabric nearer the window.

Reverse Orientation

image

Headbox protrudes inwards, making for a smooth finish and leaving more space between the fabric and the window.

*Only available for motorised blinds

Sloping KuroLok

Max Width: 2m

KuroLok can be installed anywhere up to 30° off vertical. For any blind at a higher angle, you can use KuroLok RL.

Slanted KuroLok is not a standard product, so can’t be quoted on Blindmatrix, email sales@umbrashading.co.uk for a price.

The fabric will not be completely flat on non-vertical blinds; we recommend having one sample blind fitted first to make sure that the client is happy with the result. (You can use KuroLok RL for a better result if necessary).
