Brilliant product. Made to measure loft hatch. Excellent fit, after following measurement guide on website. Looks great. Clean lines. Very well packaged for delivery. Arrived within given time frame.

This 'made-to-measure' loft hatch was produced and delivered quicker than the advertised timescale. This is my 5th such hatch bought from Jupiter Blue and I have been very pleased with all of them. This one was no different - well-made to the measurements given, and easy to fit. I would highly recommend them.

these are accurately made ... to the nearest 1mm ... so check diagonals of the loft access are equal..

Well made and fitted perfectly. Yes you pay a bit more for made to measure but the time it saved me was well worth it. The loft hatch is of great quality and so easy to fit assuming you measured correctly. The hatch frame fitted great based upon my measurements. Thank you

Very pleased with the loft hatch, I was struggling to find a loft hatch to fit the dimensions of the opening, any traditonal pre fabricated loft hatch would of meant time wasted adjusting the opening and making good the finish, the ability to buy to fit the size of opening saved time and money, the loft hatch was of good quality too, overall very pleased with this and will be using again for future jobs with obscure size loft openings.
