Little Giant 10813 250-Pound Duty Rating Extendable Plank, 13-Foot
Review by D. Golden : Just OK

This is great when collapsed to 10', but expanded to full length it doesn't "feel" as stable. I works fine, but the beams seem to flex, to and from each other, not up and down making your footing feel less than sturdy. It does hold well, but just doesn't feel like it will. In my opinion, a little pricy; of course, so are the ladders that go with it!

Review by C. Westergard : Better than expected

I own the Little Giant 17' and the Gorilla 22' ladders. (The Gorilla, of course is a knock-off of the Little Giant and is identical in every aspect.) Although each of the ladders is capable separately of using this plank as a scaffold, I didn't like how flimsy the Little Giant was when it was set up. The Gorilla comes with a nice heavy bracket that makes it very sturdy.
I purchased this plank in hopes that it would be compatible with both ladders and give me a little more height by using each laddder as one side of the scaffolding. In this respect, it exceeded my expectations and works perfectly. It's fairly light weight and easy to use. I weigh about 220 and feel safe while I am on it.
This plank costs $289 at a local dealer. I picked it up from "Little Giant Demos" for $144. No tax. No shipping.
In my opinion, money well spent.

Review by Steve Curtis "Woodsmith" : Solid work plank

Feels good even at full extension. Very handy. A little heavy but stable. If you need a work plank, then this is a good one.
