This product is intended to make installation of crown moulding and
other types of moulding (chair rail, etc.) easier. You install
brackets in key locations and attached the moulding to it. Corners
are pre-cut so the theory is you only need to miter straight pieces.
Material is a wood composite.

It is available at Lowe's and manufactured by EverTrue.

It is more expensive than wood moulding but if it doesn't look good
(gaps, etc.) or is harder to work work than advertised, etc. I would
rather use the traditional approach.

Anyone have experience with this product or something similar?

Thanks much!
