Loft Hatch Catch Manthorpe Attic Trap Door

thingiverse

This is a replacement catch for a Manthorpe Building Products Drop Down Loft Access Door. This catch is designed for UK attic trap door products, which are also available in other parts of the world. My original catch broke (see photo) and I was unable to find a replacement part. However, this new catch has some differences compared to the original Manthorpe part. The back of the new catch is solid instead of recessed, but this doesn't affect its functionality. In fact, it makes the part stronger. I also skipped adding curved corners (to speed up design) and it didn't impact usage. Update - July 25th, 2020 I've updated the file to include chamfered corners on the catch end now. The original design is shown in purple through the part images.
