I'm very pleased with this purchase.  The quality of the material is sold w/ ample weight and not some cheap plastic composite that will crumble after a season.  I was a little worried about whether or not it would fit into my existing secured downspout because the  product description did not provide the rear side measurement - the rise is 2.5" from the base; 4" across and at a height ceiling of 5".  I am extremely pleased with the purchase - the quality is sold, the price was the best around and the shipping was lighting fast!!!
