We also stock an Extruded Ladder Rung Plank option with the DIAMONDBACK® tradename. This line of Hole Products requires minimal maintenance and ensures solid footing for years. Ladder Rungs come in several primary material types and can be cut-to-length.


The following selections are important considerations to help you choose the right McNICHOLS® Ladder Rung product for your project or application. Please specify:



Product applications/uses include Rungs for rooftop access ladders, truck or emergency vehicle steps, covers over existing solid Ladder Rungs, and more. Please consider loading, span, support, and attachment needs for your project. We invite you to browse Ladder Rung applications in our Product and Application Gallery.


Construction Type

Choose from our broad selection of Ladder Rung Plank, Extruded Ladder Rung Plank, and Ladder Rung Cover Plank construction types for your project.


Series Type & Name

Determine the series type and name (GRIP STRUT® Ladder Rung Plank, GRIP TIGHT® Ladder Rung Cover Plank, etc.) of the Ladder Rung product for your project.


Primary Material / Product Finish

Select the primary material type including Aluminum, Carbon Steel, Galvanized Steel, or Stainless Steel. Inventory is typically "mill finish" unless otherwise specified. We provide more information on Primary Material Types and Product Finishes in the links provided in the Overview section on the Ladder Rung Resources landing page.


Material Guage / Thickness
