The corner braces (keys) are very brittle and some broke (they are probably about 20 years old) If we can match fit I will probably buy a quantity and replace all of them.
The pictured part has no numbers on it.
It fits into a channel 1/4 inch x 1/2 inch and the part that goes into the channel is 1 and 1/2 inches long.
The square part that does not go into the channel is 1 inch x 1 inch square.
Thank you! (and this is a nice feature to provide customers!)
