It’s a fairly heavy duty guitar amp stand.
Can hold the amplifier level or at an angle and at a few different height settings.
I couldn’t find any specifications as to the maximum weight of amplifier that it will take but it will certainly take the Fender Hot Rod / Blues Deluxe. I don’t think I would put a Vox AC30 on it or a Fender Twin Reverb. Let’s say ‘most’ 1×12″ combo’s should be fine. I have seen these used a lot by people with the Marshall AS50 acoustic amp too.

Kinsman GAS5 amp stand info:
Heavy duty with non-slip protective support rails and feet. Seven height positions.
