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.

  • I ordered a custom size hatch to replace an existing drop in lid when I fitted a loft ladder. When the new hatch arrived I was impressed by the quality, well made and finished complete with insulated lid and a breeze to fit. All in all a great looking hatch. My order was dealt with promptly, customer service was both friendly and helpful. Would recommend this product as the best our there.

  • Hi, I was very pleased with the loft hatch you suppplied. Your suggestion on the website to reduce the sizing by 5mm, due to the hole not possibly being square was spot on. The finish was to a very good quality and the measurements were exactly what I ordered. It fitted like a glove. I would definitely recommend you to other people 10 out of 10 Regards Steve Mannering

  • Loft hatch arrived this afternoon exactly 7 working days from date order was placed. Thanks to Bob who was extremely helpful with the measurements over the phone because the old hatch wasn't entirely square.The new hatch fits like a glove not bad for doing measurements over the phone.Well done.
