Catch for "cupboard" door for exterior use

[Nelly111s]

I'm making a small enclosure to house a "sign-on" sheet and clipboard, as per photo / render. It's roughly 600x450mm in size and will be outside, fastened to a wall. The door will not be locked, but I need a catch to stop the door blowing open in the wind. The catch doesn't need to have much mechanical strength, but does need to still function after a few years outside. I've even thought of just inserting a couple of neodymium magnets into the door and frame. A simple bolt could work, but I'm looking for alternatives
Any recommendations of types of catch / material that I should use?

Thanks

A simple 'Roller' or 'Ball' Catch would be my suggestion.

Do you not think that the ball will rust or stick from being outside (with no maintenance)

Use a Brass version with Stainless ball/roller. There are many versions available.

Thanks. I'll look at my local builders merchant.

Lee valley tools, but I'm sure upscale cabinet places will have solid brass and stainless. This one is $12 Canadian.

You'll probably get a much wider choice if to look n eBay and/or Amazon.

You may even find a catch which is all brass without a ball or roller which relies upon spring tension.

Something like this if the door is face mounted

For outside hardware look at chandlery suppliers, they often have nifty ideas for use on boats.

Turnbutton? as the saying goes, Kiss! Screwfix has a brass one.

Yes turn button. A scrap of wood and a brass screw.

Don't forget a holder for the pen which of course you'll put on a sink plug chain!
