I have 16 of these with screws. 2 1/2" X 1 1/2" They are like new, installed and removed the same day. They look just like your typical heavy duty stacking corner protectors but THEY DO NOT INTERLOCK. Fine for 2 different cabs. I suspect these are from another dimension, there can be no other explanation. $5.95 for postage. Please specify #6X1/4" flathead or #6X3/4" panhead screws.
