The adjustment handle allows the adapter to glide smoothly and can be locked down securely. The clamp is wide enough to attach to tree stands, in box blind windows and on security bars up to 1 inch thick. The rotating head has the BOG Switcheroo System incorporated so it can easily be installed to any BOG Tripod. The two way rotating camera head allows you to tilt up and down and pan left and right. The adjustment handle allows the SSA to glide smoothly and can be locked down securely. The accessory plate is 1 5/8 inches x 2 inches in size and comes with a standard 1/4 in-20 camera screw and a 3/8 in-16 adapter screw.
