Description
Fit-Up Pro 400 Series Pipe Spider Clamps
Internal Pipe Fit-Up Clamps, Suitable for use with Stainless Steel
This model has two independent expanding clamps, allowing independent alignment of two hollow cylindrical components of different diameters. The bottom expanding clamp is inserted and clamped in the pipe by means of the knob, then the other part (e.g. a flange) is placed over the top expanding clamp and clamped by means of the hand-bar. This model is specially suited for heavy parts. All locating rails are made of stainless steel.
NOTE: Internal fit up clamps are alignment tools. A separate lifting device to support flange weight is recommended.
