The Werner T7418 Fiberglass 18 ft. Twin Step Ladder features a duty rating of 300 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.

California residents: see  Proposition 65 information

Rated 4.8 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Large and heavy. But very stable. Didn't have the rating sticker on it but it's very stable. All two people want to carry and setup. October 28, 2014
Rated 5.0 out of 5.0 by Nice Tall Ladder I purchased this to replace a sixteen foot ladder that was stolen, I always wanted a couple more feet so this was the time to do it. It's a very well built ladder, lots of bracing so very little flex. Two big guys can work on it at once with no issues. It is on the heavy side, you're definitely going to need two people to move around. January 26, 2014
Rated 5.0 out of 5.0 by Quality Ladder This thing is big. It is not really suitable for one man to use, but it can be muscled around. Otherwise, it is very stable and sturdy. I have always been happy with the double sided ladders once I get past the weight. Also, be aware that the fully open footprint is quite large. The feet have a 43" width, and the locked open legs have a whopping 10' spread. So to use this ladder to get to something on a wall would require a large, clear space underneath to stand it beside the wall. April 28, 2015
Rated 1.0 out of 5.0 by OMG...not once did it cross my mind that I would not be able to handle a ladder. It's a ladder, who can't handle a ladder? Me. I own an antique mall. My building has 17 ft high ceilings. I thought it would be easier to change out lights and ballasts with a ladder instead of setting up scaffolding every time one burnt out. I never realized that the weight of the ladder would be a factor. I'm 5' 3" and weight 160 and this ladder is too much for me to handle by myself or with help. All you ladies out there with your own businesses...don't get this ladder unless you have a lot of help. My next step is to rent a 14 ft. ladder and see if I can handle it before I purchase it.

Rated 5.0 out of 5.0 by Good ladder I thought $700 was a bit much, but it was the only 16 foot ladder I could find. However, I am very happy with it and would buy it again. It is heavy & bulky for one person, but it can be done. It does have a large span, as you would expect, but it is extremely stable, which I love since I hate heights. I paid to have it delivered to my home at it was well worth the money. They put it where they said they would and it was actually a couple of days early. December 9, 2014
Rated 5.0 out of 5.0 by Perfect solution! This ladder is really big and honestly needs two people to maneuver and set up; but it was the perfect solution for being able to work with fruit trees. My husband can get up above the top branches when spraying them and the spray goes down on other branches also instead of back on him. Also, we can now reach the amazing fruit that always seems to be on the tip top of the tree on smaller branches. This ladder is very sturdy. Both my husband and son felt very secure climbing very high on it. We added hooks in the garden shed to hang it on and it's out of the way when we don't need it. Perfect fruit tree solution!

Rated 5.0 out of 5.0 by the best ladder Ladder is very easy to move with only one person handling it January 27, 2015
Rated 5.0 out of 5.0 by Great Ladder We use this ladder all the time to work on ceilings of homes. I would suggest it for everyone April 22, 2014
