Planks, Guardrails, and Toeboards

Create catwalks, bridges, gangways, and mezzanines by combining these planks, guardrails, and toeboards. They also work well between trestles, ladder jacks, and ladder scaffolding supports. Rungs on the underside are for use as hand grips.

Planks have a slip-resistant surface for sure footing. The vinyl end caps protect against sharp edges and act as hand grips.

Note: Planks, guardrails, and toeboards meet OSHA dimensional standards. Users are responsible for checking local, state, and federal codes, including OSHA, for safe installation and operating practices.

Extension Planks

Shown Partially Extended

For use with ladder jacks, trestle ladders, and walkways, adjust the length of these planks in 12" increments. They have a ribbed surface for slip resistance. Planks have a spring-set lock to secure the extended position. Automatic stops prevent overextending, and end flanges maintain rigidity.

Note: Planks meet OSHA dimensional standards. Users are responsible for checking local, state, and federal codes, including OSHA, for safe installation and operating practices.

Scaffold Planks for Harsh Environments

Aluminum is a good choice for damp areas and outdoor use. Hooks with a 2" opening at each end secure planks to end frames. Rungs on the underside are for use as hand grips. Planks have a perforated surface for slip resistance and to reduce debris buildup. End hooks are offset to allow for continuous planking of large scaffolds.

Note: Length is measured from center-to-center of end hooks.

Note: Planks meet OSHA dimensional standards. Users are responsible for checking local, state, and federal codes, including OSHA, for safe installation and operating practices.
