The Roberts 10-254V Power-Lok Carpet Stretcher is the most advanced power stretcher available. The built in handle switch allows the user to lock the head in 17 different stretch/pattern holding positions. The low profile head with side kicking platform makes it compatible with knee kickers. The 18 in. tail block includes a foam wall protector and wheels for easy repositioning. A must when installing carpet in rooms larger than 10 ft. x 10 ft.
