The Stileline Monterrey series offers a routed solid core MDF door with an applied inlayed moulding. The wide moulding lips over the routed area, to create a clean distinguished look. The Monterrey doors are offered in 15 square panel designs. Currently the Monterrey doors are only available in the 1 ¾” thickness, or for 1 3/8” thick doors with a flush back (i.e. bi-fold doors).
