The SUMNER 4100 is a Hi V-Head style jack stand designed to support pipe, conduit, and similar round stock during layout, assembly, and installation work. Standing 24 inches in height, this jack stand holds workpieces securely in the V-head cradle, keeping material stable and at a consistent working elevation. It is a standard tool in the inventory of plumbers, pipefitters, electricians, and mechanical contractors who need reliable hands-free support during field fabrication or rough-in work.
The 4100 is suited for use on commercial and residential job sites where pipe or conduit runs require staging before final installation. Typical applications include supporting sections of pipe during threading, cutting, or joining operations. The Hi V-Head configuration accepts a range of round stock diameters, making it a practical stand for multi-trade use in mechanical rooms, utility corridors, and open framing environments.
Designed as an OEM-style jack stand compatible with standard pipe and conduit support applications across plumbing, pipefitting, and electrical trades.
Set the stand on a flat, stable surface before loading pipe or conduit into the V-head cradle. Confirm the workpiece is fully seated in the cradle before beginning any cutting, threading, or joining operation. Do not exceed the rated load capacity of the stand. Inspect the stand for damage or deformation before each use.
