For use with a PM5, PM4 or PM3, the Smartphone Cradle slides onto the top of the PM to provide a place to set your mobile device while using the indoor rower, SkiErg or BikeErg.
The cradle will accommodate smartphones of various lengths. The adjustable arm can hold phones as narrow as 2.25 inches (5.7 cm) in width and can stretch open to 3.5 inches (8.9 cm) in width (for reference, this is large enough to accommodate an iPhone 7+ with or without a case).
