The WILLIAMS WG-3 is a 3-inch set-up wedge used to level, align, and position machinery, equipment bases, and structural components during installation and maintenance work. Weighing 0.133 pounds, this compact wedge delivers dependable holding force without adding bulk to a tool kit. It is manufactured in the United States and sold individually. Millwrights, pipefitters, plumbers, and general maintenance technicians reach for wedges like this when shimming equipment to precise alignment before final fastening or grouting.
The WG-3 fits common trade scenarios where temporary or permanent positioning is required beneath machinery bases, pump skids, pipe supports, or HVAC equipment feet. Its 3-inch size suits tight spaces and smaller equipment frames where a larger wedge would be impractical. It is suitable for both residential and light commercial installation work across mechanical, plumbing, and general construction trades.
Designed as a general-purpose set-up wedge suitable for leveling and aligning machinery bases, equipment skids, and structural supports across mechanical and construction trades.
De-energize and lock out all equipment before positioning wedges beneath machinery or equipment bases. Drive or place the wedge by hand or with a mallet to achieve the desired alignment. Verify final position with a precision level before completing permanent fastening or grouting. A licensed tradesperson should confirm that final installation meets applicable local and national code requirements.
