The cheapest outdoor boxes I find that are quick opening are the ones sold
as "60 amp AC Disconnects". These are the boxes that go on the wall out
at your AC or heatpump.
Get the one without fuses and you get the box and 60 amp pullout switch
for only $7 or so.
I use lots of them (on my solar and other high power stuff) where I use
them for the required Solar Disconnect, for series parallel switching of
the arrays from 500v to 250v so I can use the DC power directly during
grid outages, or for A/B switching to my backup generator, etc. They are
Dual pole switches and 60 amps! For $7 with box.
For the generator switching I pull the guts out of one and add it inside
another one so that it becomes a DPDT transfer switch by moving the
pullout from one slot to the other.
Removing one screw and all the disconnect swtich stuff falls out and
leaves a clean box.
Not bad for outdoor WX enclosure for $7.
But MAYBE NOT FOR A MAST where rain can be blowing up from any direction
besides DOWN. Then maybe some rain can blow in the cracks?

I'm using a 8x8x4 outdoor electrical box with the two preamps stacked on
top of each other.

Looking to move my two mast mounted preamps into an enclosure. Who knows
of a good mast mounted waterproof enclosure that will handle 2 Advanced
160 Watt Mast Mounted Amateur Preamp's inside? The preamps are 5" wide and
2-1/2 deep. I could stack them on top of each other or side by side. Let
me know if the suggested enclosure will have the hardware to mount to the
Provide me with links to the items.
