The T7412 Fiberglass 12 ft. Twin Step Ladder features a duty rating of 375 lb. per side of the ladder. Designed for one or two-person jobs, the T7400 ladders have heavy gauge aluminum tops and feature heavy duty internal spreaders to resist damage around the worksite or in transit. The glas mark violator stripes on the rails make the ladder more visible and the edge bracing system and external rail shields add to the long lasting durability of these ladders. Fiberglass rails are non-conductive for working near electricity.

  • Heavy gauge aluminum extruded top with thick side plates
  • Back-up aluminum plates reinforce all top connectors
  • Shoulder bolts and lock nut on top hinge, 4-solid aluminum rivets attach top to each rail
  • Slip-resistant traction-tred steps are doubling riveted and knee-braced

Rated 4.8 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by Heavy duty ladder but... The ladder's overall strength and versatility is good in that you can climb or stand on either side but I was disappointed with the single stabilizing brace it has. Would feel a lot better 12 feet off the ground if it was constructed with some kind of additional bracing. June 17, 2014
Rated 5.0 out of 5.0 by Great Ladder This Werner ladder is well-built and tall enough to let me reach the eves of my roof safely. Having steps on both sides allows me to have a helper with those tall jobs. A very pleasant discovery was that this ladder is rated for 375 pounds for EACH side! June 17, 2014
Rated 5.0 out of 5.0 by Sturdy & heavy-duty quality. Very sturdy & ideal for just about anything you might need around your home; really a professional grade item. It is heavy & awkward to move (due to it's large size), so be sure you can handle it alone or have a helper for moving it. April 29, 2014
Rated 5.0 out of 5.0 by So glad I made this choice! This was a great experience all around. I had wanted this ladder but kept putting it off. Finally decided to do it but the only source was out of town. I ordered the ladder, it arrived quickly for in store pick up. The transaction was quick, ladder loaded and I was off! This is a very tough, durable ladder yet easily manuervered into place, carried, and feels steadier than any of my other ladders. The twin sides are great! It has been home a week, tall hedge is trimmed! Next will tackle the windows. April 21, 2015
Rated 5.0 out of 5.0 by Nice ladder Nice sturdy ladder. Does not wobble, use from either side is nice. June 16, 2015
Rated 5.0 out of 5.0 by Glad with this purchase The ladder isn't cheap, but I can use it together with my 16-years-old son to work at home. June 2, 2015
Rated 5.0 out of 5.0 by step ladder super ladder, a little on the heavy side, but it holds my fat butt !! March 10, 2015
Rated 4.0 out of 5.0 by Great Ladder! Great ladder, nice that you can either straddle the ladder using the rungs on both sides or two people can stand on it in case you need an extra pair of hands. April 29, 2014
