Werner 20 Ft. Type IAA Fiberglass D-Rung Extension Ladder with Cable Hook, V-Rung, and Werner LevelSafe Pro Leveler

Description

Climb live utility poles and strand wire with confidence using this Werner 20 Ft. Fiberglass Extension Ladder. Non-conductive fiberglass side rails insulate line technicians near energized primary drops. Integrated cable hooks and V-rungs grip guy wires without slipping. Factory-installed LevelSafe leg levelers add four pounds of base iron, making single-worker carries bottom-heavy over rough ditch turf.

The rails utilize seven-layer pultruded non-conductive polyester fiberglass with seven-eighths-inch web thickness to prevent electrical arcing. Slip-resistant 1-1/2-inch aluminum D-rungs swage direct to the side rails with cold-formed rivets. Dual aluminum gravity rung locks feature spring-loaded steel cams. The ladder supports an ANSI Type IAA 375-pound duty rating. Unboxed equipment weight totals 54 lbs, holding closed transport dimensions of 120 inches long by 19 inches wide.

Rail Deflection Torsion Bench Tests

Proof-load testing on a horizontal test rack subjects the twenty-foot ladder to three hundred seventy-five pounds at mid-span. Vertical rail deflection measures 1.4 inches, springing back to zero camber without fiberglass resin fracture. Cantilever rung tests withstand one thousand pounds without joint loosening. Torsional twist under off-center loading holds within 1.8 degrees along the twenty-foot extension. The LevelSafe leg locks sustain eight hundred pounds of downward axial force without pawl slippage or ratchet tooth shear.

Lineman Pole Rigging Maintenance Tips

The bottom-mounted leveler shifts the balance point toward the feet, requiring a firm shoulder grip during carry. Smooth rope and pulley hardware hoists the fly section without snagging. Do not use this heavy pole-climbing ladder for light interior ceiling maintenance where short stepladders suffice.

• Wipe fiberglass rails with silicone paste to protect the gel coat from UV breakdown.
• Inspect cable hook weld joints and spring returns for cracks before each ascent.
• Clear mud from LevelSafe ratchet teeth using stiff bristle brushes.
