• Dual Lock Recommendation: For widths exceeding 750mm on the hinge side, two locks are recommended to ensure a secure, tight draught seal.
Construction & Locking:
• Construction: Fabricated from corrosion-resistant 1mm Zintec Steel. All hinges and fixings are concealed.• Standard Lock: Tri-drive lock featuring an O-ring seal on the shaft for ultimate airtightness. Optional Key lockable version also available.

Superb loft hatch made to measure to suit. Needs a second pair of hands just to get the initial fitment in place. Fits like a glove, looks great and operates as intended.

Fast service, perfect loft hatch, exactly as described - could not fault anything with our purchase. Also a nice (and refreshing) touch that they donate to some of the proceeds to charity but don't use it in their marketing. Would absolutely buy from them again.

Needed a custom size loft hatch due to our loft opening and ordered this from Jupiter Blue. Previous hatch was very draughty but this did the job. Builders fitted it with no issue and no it looks so much better. Highly recommended!
