Questions & Answers


How wide does this open? I need very occasional access to clear gutters, check roof felt etc


Approx 6-8 inches as It opens on a chain system - I will send you a quote for the correct sized one. 


Can this window be fully opened for escape


No, you would need an escape hatch


What are the internal dimensions of the box frame of 80cm square dome that is hinged with manual lift mechanism?


The structural opening size would be the same as the  size of the window


Does the opening spindle detach?


Good Morning Julia

No, It doesn't detach - if you need something that will then have a look at Mardome Trade Double Skin Access Hatch in Clear - 1050mm x 1050mm | Roofing Superstore®
