The Crain Mini Carpet Stretcher is great for pattern matching, fast restretching without tubes, and seam repair. Features include a stretch-lock button, two fully pivotable gripper heads, an open-top wall blade for fast tucking, and a carrying case. Gripper heads and wall a blade are quickly connected onto either end using the push-button lock pins. Tall seam repair legs that create a 9" high by 10" wide work area to run an iron beneath are sold separately (No. 519).
