Gibraltar 40103G Steel Step Block 2 Piece Height Adjustment

Product Description

The GIBRALTAR 40103G is a 2-piece steel step block designed to provide adjustable height support in a range of trade and industrial applications. The block adjusts from 1-1/8 inches to 2-1/2 inches in height, allowing the installer to dial in the correct elevation for the workpiece or component being supported. Each step increments by 1/8 inch in elevation, with a step depth of 1/16 inch. The base depth measures 1-39/64 inches, the overall width is 1 inch, and the collapsed height is 1-1/16 inches. Constructed from steel throughout, the 40103G provides reliable load support without flexing or compressing under typical service loads.

Step blocks of this type are used in machine shops, fabrication environments, and mechanical service settings where work must be elevated and held steady during cutting, drilling, pressing, or assembly. The 2-piece stacking design allows the technician to build up height in controlled increments. This makes the 40103G suitable wherever a fixed-height support would either fall short or create interference. The compact 1-inch width fits into confined staging areas where larger blocks would not seat properly.

Key Features

• Height adjusts from 1-1/8 inches to 2-1/2 inches in a 2-piece stacking configuration
• Step elevation of 1/8 inch per increment for controlled height buildup
• Step depth of 1/16 inch provides consistent seating between stacked pieces
• Full steel construction resists deformation under load
• 1 inch overall width fits in tight workspaces
• Base depth of 1-39/64 inches offers stable footing on flat surfaces

Compatibility

Designed as a general-purpose steel step block for use in machining, fabrication, and mechanical service applications requiring adjustable workpiece elevation support.

Installation Notes

Step blocks are typically positioned and set by machinists or mechanical technicians working with mills, drill presses, or press fixtures. Ensure the mating surfaces of each stacked piece are clean and free of chips or debris before assembling to prevent uneven seating. Do not exceed the rated load capacity of the block set and confirm the work surface is flat and stable before applying clamping force. No special tools are required for assembly.
