New to the Pro-Stretch Carpet Installation System is the powerful, yet versatile, Air Mini Stretcher. The MS-2000 is a replacement for the Mini Stretcher (aka. Crab) and can be used to stretch carpet to CRI specifications in small to mid-sized rooms. More powerful than an Air Stretcher and more versatile than a Power Stretcher, the MS-2000 is an excellent production tool on mid-sized to large crews.
