Products assembled with NYLON CORD generally ROLL OUT (or ROLL UP) for easy installation & removal, so we call this "ROLL OUT" Construction.
| Products assembled with STAINLESS STEEL RODS are shipped in semi-rigid sections that flex in all directions, contouring to almost any surface, even turning slightly to the left or right for curves. The sections quickly & easily bolt together. We call this "Flex" Construction. |
