FREESTANDING AND PORTABLE - Standard Partitions stand up completely free of the wall with their end support frames and locking casters. The self-leveling casters adjust to minor imperfections in the floor surface, making the panels easy to use and operate. SOUND ABSORBING AND TACKABLE PANELS - Each panel of a Screenflex Standard Room Divider contains a closed cell honeycomb core that traps pockets of sound. They also have two layers of sound-absorbing fiberglass on top of that for additional acoustical properties. These temporary walls help facilities be more acoustically balanced while creating new private spaces. DURABLE AND LONG-LASTING - These portable office walls are proven to last for decades and are easy to maintain. The end frame design keeps the center of gravity low to the ground for enhanced stability. ACCORDION-STYLE FOLDING & COMPACT STORAGE - All Screenflex room dividers fold accordion-style, which allows them to create a variety of shapes to customize your space. This freestanding room divider design also enables the screen to close into a tight space for compact storage. SHIPS FULLY ASSEMBLED - Ships fully assembled and ready-to-use.
