Solid Aluminum Rivet Construction

Solid aluminum rivet construction at critical stress points is stronger than tubular steel rivets and results in a longer service life for your ladder.

Two-Way Suction Cup/Spike Shoe

The shoe attachments on the 315 series are reinforced with heavy gauge aluminum reinforcement sleeves to provide a stronger connection point for our suction cup/spike shoes.

Center-Point Bull’s-Eye Label

Allows for easy determination of the center-point for the weight of the ladder for safe lifting and transportation.

Safety Red Rungs

Highest standing level is clearly defined and has never been easier to determine. It’s easy… don’t stand on red!

Upgraded Rope Is Standard

³/₈” diameter poly-plus rope. Same rope the repair companies use. Save $30–40 by having it factory installed.
