A ramp with a pie platform can be adjusted at a 45-degree angle. This allows its lower elevation to face a different direction than the higher elevation. A pie section is useful for navigating a sharp turn.
Depending on your household, the type of ramp you get might be required to have an adjustable pie section if the amount of space is too small for a different option. The pie section makes it easier for someone to travel around a turn in a wheelchair or other accessibility device.
It is a specialized platform that can save someone with a disability more time than another type of ramp when navigating from one space into another.
