Abstract
A mountable roller device for ladders. It is capable of integrating and attaching to step ladders, extension ladders, or most other standard ladders. The mountable roller device has a pair of side latches for connecting to the legs of the ladder, and also includes a plug for inserting into the void within the ladder steps of a typical ladder. Once affixed to the ladder, the ladder can be tipped and rolled along the roller wheel of the device. The roller wheel includes a groove to allow the device to be used as a pulley system with the ladder.
