The RIDGID® 915 Roller Groove is a manually operated roller groove for applications in existing workshops. The 915 requires only 3 1/2" (9cm) clearance to move around the pipe and a minimum of 2 3/4" (7cm ) of exposed pipe to groove. With the right roller sets, you can use the 915 to perform grooving operations on pipe from 1 1/4" to 12", the largest range in its class! The 915's moulded handle facilitates transport or can be used to chain the roller groove set to prevent theft. The 915 is indispensable for service work.
