Bespoke Sizing & Installation Guidance:
• Custom Sizing: The hatch is made to your exact measurements, requiring the length and width of the loft opening (joist to joist) in mm, with a 5mm deduction for fitting tolerance.• Frame & Protrusion: The hatch frame depth is 63mm (up into the loft), and the finished panel has a minimal protrusion of 7mm from the ceiling, ensuring a subtle, clean aesthetic.
• 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.

The best loft hatch that you can buy. Highly recommend.

Fantastic loft hatch, highly recommend.
-
Nicely made and finished. You really need help from an assistant to install. That's because the frame and hatch are not intended to be separated. End result looks very good and big improvement on the original 1970s hatch.
