Hafele sells these 4” x 4” polyethylene corner braces for cabinets.  Everything I have used so far from Hafele has been “professional” grade.

When I need a corner bracket currently, I cut a piece of plywood to size and add either two or four pocket screws. 

The Hafele brackets cost $0.25 each and use less expensive 1/2” truss head screws.  From both efficiency and cost perspectives the resin corner brackets make sense.  But are they any good?

I buy some Hafele hardware on occasion.  If this is a good product, I will add it to my next order. 

Does anyone have experience with these?

From an appearance point of view, I agree with you.  They look cheap. 

But I am of the generation whose bicycle’s metal parts stood up and the plastic parts failed. 

Years later, that was no longer the case.  Engineered plastics cane stand up better than metal parts in some instances. 

These are not made from engineered resin, but also not from polystyrene. 

If these do not compromise the strength of the cabinets, they are going to be much faster and easier to install—and less expensive too. 

I would like to hear from people who have used these.  I’ve used stamped steel braces.  But those cost $2.50 per corner, so an entirely different animal.

I’ve used these, and I see that they are $3.20 each.  Very compact and I needed that to allow the sink to fit a small cabinet.

Most of the time, those are used as corner supports/ countertop connection points in sink-base cabinets.
That leaves the most available open space for the sink to fit, without having to cut into the typical stretchers of a normal base cabinet.
