Adam Hall 4013 Cabinet Corner

I used these for the corners of a home made speaker cabinet . They finish it off nicely. Take into account that they are made of plastic so they will only take a certain amount of punishment but they do the job. Also note that the edges of the cabinet have to be rounded for these to fit snugly. Good price.

I saw those corners used by GK and when I built my own cabinets, my first idea was to use those, too. But I found them to be unhandy to use.
first of all you have to route the edges, which I did not want to do. OK, you cannot blame the corners to be designed that way, but I wish they would make a version for un-routed edges, too.
Secondly, they just don't seem stable enough to me. Cannot help it.

Made from durable plastic, this is a best solution i found so far for saving my cabinet edges from accidental hits. 2 holes on each side provide you best fitting on your gear. They look great! Make sure you measure external radius on your gear for best inner radius fitting!

It is made of plastic so ofcourse not the most sturdy ones out there. The plastic itself however feels quite nice and doesn't seem like it is going to break anytime soon!

I do sometimes rip these corners off my bigger speaker, or amp boxes, I sometimes lazily push my cabs hard at spring back doors, only to find a broken corner. So here they are guys, big ones, or small ones, keeping our music gear looking good for a long time.

Commoner garden corner protectors , not amazing quality, I'm not sure about how much abuse they would take before cracking and breaking off.

Good stackable plastic corner for speaker cabs. Great as a retro fit to smarten up tatty and worn cabs. Have used when refurbishing old SWR bass cabs. Look like new. Good value do the job well.
