The grip feet are designed to be wrapped by your hands, similar to the handlebars on a bicycle.
Designed for Sliding
Once gripped, use them for sliding the XOOT system around the desktop.
Push, pull, or turn; put the base where ever you need it.
The bottom of the grip feet are covered by a slippery pad.
They work best on hard surfaces like laminate desks.
Warning Softer materials like wooden desks can be damaged by the XOOT system sliding on top.
