Gibraltar 40106G Steel Step Block 2.5 to 6 Inch

Product Description

The GIBRALTAR 40106G is a two-piece steel step block designed to provide adjustable height support for workholding and fixturing applications in machine shops and industrial settings. The block adjusts from 2.5 inches to 6 inches in height, allowing it to accommodate a range of workpiece thicknesses and clamping setups. Each step increment is defined by a 1/16-inch step depth and 1/8-inch step elevation, enabling precise, repeatable positioning. The 40106G is constructed from steel for durability under clamping loads. It is typically installed by machinists, toolroom technicians, and maintenance professionals.

This step block is suited for use on milling machines, drill presses, and surface grinders where T-slot clamping systems are used. The 1.5-inch width and 3.75-inch base depth provide a stable footprint on the machine table. The 2-piece design allows the upper and lower sections to be separated and repositioned to match the required support height for the workpiece being secured. The base height measures 2-15/32 inches. The block weighs 3.08 pounds.

Key Features

• Height adjusts from 2.5 inches to 6 inches to suit varied workpiece thicknesses
• 1/16-inch step depth and 1/8-inch step elevation for precise positioning increments
• Two-piece steel construction withstands clamping and machining loads
• 1.5-inch width and 3.75-inch base depth for stable table contact
• Base height of 2-15/32 inches provides a consistent starting reference

Compatibility

Designed as an OEM-style replacement and standard-duty step block for use with conventional T-slot clamping setups on milling machines, drill presses, and similar machine tools.

Installation Notes

Step blocks are installed by machinists and toolroom technicians as part of a T-slot clamping assembly. Always ensure the machine table is clean and free of chips before seating the block. Confirm that the step block height matches the clamping strap angle before tightening fasteners. Do not exceed the rated clamping load for the block size in use.
