Gibraltar 40104G Steel Step Block 2.5 to 6 Inch

Product Description

The GIBRALTAR 40104G is a two-piece steel step block designed to provide adjustable height support during machining, fixturing, and workholding operations. The block adjusts from 2.5 inches to 6 inches in height, giving technicians and machinists a range of positioning options without swapping out multiple fixed-height blocks. Built from steel, the 40104G offers the rigidity and durability required for production and maintenance environments. Key dimensions include a 1-inch width, 3.75-inch base depth, and step increments of 0.0625-inch depth with 0.125-inch elevation per step. The unit weighs 2 pounds.

Step blocks are commonly used in machine shops, maintenance facilities, and fabrication environments. They are typically paired with T-bolts and step clamps to secure workpieces to milling machine tables, drill press tables, or surface plates. The adjustable two-piece design allows a single block to replace several fixed-height blocks, reducing the number of accessories required for varied workpiece thicknesses. This block is suited for general metalworking and light industrial fixturing applications.

Key Features

• Adjustable height range from 2.5 inches to 6 inches accommodates a wide range of workpiece thicknesses
• Two-piece steel construction provides rigid, stable support under clamping loads
• Step depth of 0.0625 inches and step elevation of 0.125 inches allow precise height positioning
• 1-inch width and 3.75-inch base depth suit standard step clamp and T-bolt setups
• Weighs 2 pounds for easy handling and repositioning during setup

Compatibility

Designed for use with standard step clamp and T-bolt workholding systems on milling machines, drill presses, and similar machine tool tables.

Installation Notes

Step blocks are positioned and adjusted by machinists or maintenance technicians during workholding setup. Always ensure the machine table and T-slots are free of chips and debris before seating the block. Power down and lock out the machine before adjusting or repositioning any clamping components. Verify the block height and clamp alignment are secure before beginning any machining operation.
