A:  I haven't measured the total length, but they fit in standard 5x7 staging/scaffolding and work great. Hope this kind of helps.

A:  Good day, the platform is 7ft from the middle of the hook to the middle of the other hook.

A:  It's only about a 20 degree up slope so they would not have a problem

A:  We have had no problem with slippage,they work fine

A:  They do not slip at all. I mostly use mine on scaffolding but I am using one as a ramp going up approximately 30 inches and it works great. 

A:  Good day, please send us your question via email at cs@metaltechna.com we will transfer it over to our engineering departement to get the answer for you. Thank you

A:  Very lightweight, around 20 lbs. each

A:  20 lbs +

A:  Hi, width is 19 inches, length is 7 feet. Thanks!

A:  like 20 lbs.each ,it has ben some time since I have used all 6 of my platforms. Remember, the weight limits are important for safety.

A:  75 pounds per square foot means each square foot can support75 pounds. If you multiply by the square footage of the plank, then you get what the plank can hold, so long as you don't exceed 75 pounds per any given square foot of plank. If the three planks are side by side, then their total square footage times 75 pounds per square foot would give you the total load three planks side by side can support, again, if you don't exceed 75 pounds on any square foot of surface.

A:  So you've done the math and arrived at the answer. That's an evenly distributed weight by the way not a point load and not unbalanced. They will hold the weight but they are fairly flimsy compared to a standard scaffolding plank.

A:  load is 250 per plank

A:  I weigh 250 + approx 30 lbs of tools. One person would stand on approx four square feet at any giving time, so I personally would not use these if I weighed over 300 lbs, and would not double are triple stack under no circumstances. This is an excellent product within its range. I work by myself, they are great for the ease of moving them.
