Very easy to fit. Size was accurate. This was a bespoke loft hatch and it was so useful to have it hinged on the most appropriate edge.
-
Great loft hatch. Makes a big difference to the temperature of the house. Very easy to install, just a bunch of screws. Due to the size, I would recommend 3x people to install - two to hold in position, one to mark up & drill.
-
Great looking product & easy to fit. It arrived ahead of the scheduled time. Highly recommended & we’d certainly use Jupiter Blue again.
