Haven't posted here in a while!
But I had a look at an Apple Juice carton closer and had an idea!
Always looking for doors to separate corridor or rooms from the complex. I have started taking these off of certain juice cartons.
Add a wheel to the handy little pin locator that they have and presto! Bulkhead door!
Just stick to base of your own choosing!
Painted very roughly as I did about two dozen of these.
Locking side with added sealing wheel!
Outer side nice and smooth!
Very useful and recycling is the key!
