Sometimes a shelf is so high that you hardly use the upper storage room because it is not convenient to reach. While a normal ladder might be a little bit too heavy for a teenager or a lady, these easy gliding rollers designed for ladders help you glide the ladder left or right with minimal effort.
The clearance between the base of the shelf and the tip of the bottom of the ladder depends on the length of the ladder, which becomes the hypotenuse of the right triangle formed by the wall of shelves, the ladder itself and the floor between the base of the ladder and the wall of shelves. Using the Pythagorean Theorem you can solve for the distance you seek.
We have also given a simple formula L =H-1 9/10'' (with L means Ladder Length and H means the point that the roller’s strap starts to bend, this point is also where the top tip of your ladder should be). Made with high quality steel and with black powder coating finish, this hardware set matches many colors of your shelf and ladder.
Some customers do not like bottom rollers because they thought it is dangerous to have roller on both top and bottom sides, therefore, we removed the rollers from the kit. If you still need the rollers, you can buy the rollers separately. *BOTTOM roller not included. *Ladder not included. *Assembly required.
