Pacific Clay 076502000 3-5/8" x 1-1/4" x 12-1/2" Red Flashed Retrofit Bullnose Coping 400 per Pallet. Retrofit Bullnose offers the charm of real fired clay brick as well as the low cost installation time of standard concrete pool copings. Because it has been designed with direct input from contractors and distributors, it's easier to install and more flexible in design consideration than ordinary bullnose. Retrofit is longer (12-1/2") and thinner (1-1/4") than traditional bullnose, so it easily replaces concrete coping without having to cut the bullnose or grind the bond beam. Retrofit Bullnose offers a flat, round end (as in traditional bullnose) for more linear aesthetics.
