Expect exciting new colors to complement any décor with ClosetMaid’s new MasterSuite collection – 27^th Avenue. The collection will be showcased at IBS and available to the market in late Spring 2018. Premium finishes include a white woodgrain, blonde woodgrain, gray woodgrain, solid taupe, and slate finishes for a modern, clean painted look. Three upgraded front styles, two new island top finishes, and three new cabinet pulls add to the wide array of personalized choices for the system. 27^th Avenue offers the design updates desired by consumers, architects, and builders alike.

MasterSuite is a high-end closet and storage system made from industrial grade engineered wood with a highly durable melamine finish, and solid wood drawers. The system provides near limitless configurations of shelving, cabinets, drawers, hang rods and other accessories to accommodate any space in the home.

ClosetMaid will also have enhancements to ExpressShelf on display – including new hardware options enabling full walk-in and wall-to-open shelving configurations, continuous slide corner solutions, and extended shelf applications. Plus, ClosetMaid will offer a sneak peek at the system’s new premium ventilated wood shelving options.

ExpressShelf is a design and build, pre-finished shelf and rod system which debuted in 2017, and is now one of ClosetMaid’s most in-demand products. With its attractive and intelligent patent-pending hardware, ExpressShelf installs quickly and easily with basic tools and eliminates the need for ladders, caulking and painting. These features allow increased time efficiency while maintaining consistent quality, fit and design.

Finally, ClosetMaid will showcase its customizable SpaceCreations system. This stylish wardrobe-like system can be completely personalized and customized even further with two new Premier finish options, Cool Gray and Bright White. SpaceCreations is a DIY-friendly tower-based system that can be configured in a variety of designs and outfitted with a wide range of accessories to match every consumer’s style and storage needs. Previously available in two different styles, Classic White and Premier Dark Java, SpaceCreations' new finish options, Cool Gray and Bright White, work to create a custom feel with a designer look in any room of the home.
