The SBH-180DS is a compact ball head with an Acra-Swiss compatible quick release system.  The ball head is currently available with the LITE series CF-422 and CF-522 tripod kits as well as being available separately.  To mount on a tripod the head has a U3/8 tripod mount with a U1/4-20 reducer for either sized tripod mount threads.  

This durable, simple-to-use ball head has a single lever to lock and release the ball for repositioning of the camera and a small, low-profile quick release plate that can be left on the camera at all times so it’s always ready.  With a maximum capacity of 6.6 lbs the SBH-180 was designed for light-weight DSLRs and mirrorless cameras.
