• The Hornet U-4064 Smart Phone Mount comes complete with a SOLID Crab Clamp that can attach to any square, round, or oval tube up to 1 1/4" diameter. (tool less installation)
• The Crab Clamp base attaches to the Hornet Quick-Adjust arm.
• Unlike the friction adjustments used on most camera mounts, this unique arm has a unique mechanical design where a simple twist of the elbow knob loosens the entire arms AND both ball sockets on the ends so you just loosen, adjust to the desired position, and lock it in place with a simple half turn of the knob.
• The phone holder attaches via standard SAE 1/4" thread so you can also use it to hold your Go Pro or other action camera.
