The Ultrajax I is the string silencer that put Bowjax on the map as an industry leader in vibration dampening technology. This silencer does not require a bow press for installation, simply slide it over the string and cinch it down with the included zip ties. Since they fit over the string, they will not affect peep sight rotation or point of impact, making them the choice for last minute bow silencing.
Vibration reduction without loss in arrow velocity
Weigh only 21 grains
No bow press required for installation
