The innovative 448SW Series is the only pullout on the market featuring two swiveling shelves for easier access. The shelves feature a built-in self-centering system and chrome railing that not only keeps items in place & looks great but doubles as a handle when rotating the shelves. The self-centering system also features soft-closing, which gently returns the shelves to their closed position. Another exciting feature of this pullout is an "extension lock" that locks the entire unit in the extended position to prevent it from sliding back into the cabinet while it is being accessed. Designed for full-height cabinets, they are constructed from natural maple with a semi-gloss finish and glide on BLUM slides w/ soft-close. Just add an existing cabinet door to provide seamless integration into any design.
